Field
[0001] The present invention relates generally to the field of data analysis. More particularly,
it relates to a prayer rug configured to determine a progression in prayer of a user
by means of a sensor. The present invention also relates to a system comprising the
prayer rug configured to determine the progression in prayer of a user, and to a method
and a computer program product therefor.
Background
[0002] Praying is an important tenet of most religions. As such, it forms an important part
of people's lives around the world. Praying may involve following a specific, defined
sequence of movements. For example, in some forms, praying may involve a person repeatedly
standing upright, followed by prostration allowing the forehead to touch the surface
underneath. It may be of advantage to use a prayer rug or mat when praying in this
case. A prayer rug may be of further advantage in protecting a user from cold, moisture,
and/or mechanical wear, especially on the knee joints, while praying on the ground,
for example.
[0003] Further, a defined number of repetitions of the specific movements may be needed
to be performed for each prayer session. The number of repetitions performed may define,
at least in part, a progression in prayer of the user. A relevant consideration may
then be to keep track of the progression in prayer. Different methods may be used
to keep track of the progression in prayer. For example, a smartphone application
may be used. Alternatively, an interface may be provided directly in the prayer rug
that may allow the user to update their progression in the display. However, either
of these solutions may involve breaking the prayer and updating the data in the application
that may not be ideal.
[0004] Automatically recording the progression in prayer is also known and may be more advantageous.
US 11,432,671 B2 discloses a smart prayer rug including a display screen, one or more pressure sensors,
and one or more proximity sensors. The prayer rug may also include one or more speakers.
The pressure sensors are configured to sense a change in pressure applied at a number
of pressure points and output pressure information. The proximity sensors are configured
to sense a distance an object is away from the one or more proximity sensors. The
prayer rug is part of a system comprising a processor that may determine a prayer
posture from the received pressure and proximity information and that may generate
an alert if the determined prayer posture is detected as being incorrect.
[0005] While the solution presented in the prior art is useful, it may also have some disadvantages.
A particularly relevant disadvantage may be the complexity and difficulty of use of
the system.

Brief Figure Description
[0240]
Figure 1 depicts a schematic view of a prayer rug comprising sensors; and
Figure 2 depicts typical data that may be recorded by the sensor of the prayer rug.
Detailed Figure Description
[0241] Figure 1 depicts a system 1 configured for determining a progression in prayer of
a user. The system 1 may comprise an external device 2 and a prayer rug 3. The external
device 2 may comprise a smartphone, a laptop, a desktop computer, a tablet, or any
other suitable data processing system. The external device 2 may also comprise a remote
computer and/or a remote server.
[0242] Communication between the external device 2 and the prayer rug 3 may preferably be
carried out wirelessly. However, in embodiments, the communication may also be carried
out over a wire. The external device 2 may comprise, for example, a communication
unit that may interface with a communication unit of the prayer rug 3, via an intermediate
router, for example. Thus, generally, it may be understood that the prayer rug 3 may
communicate with the external device 2.
[0243] The prayer rug 3 may generally comprise a significantly planar rug, such that an
extension, that may be called a thickness, of the prayer rug 3 in one dimension may
be significantly smaller than an extension, that may be called a width and a length,
of the prayer rug 3 in any of the 2 other dimensions. Generally, the length of the
prayer rug 3 may correspond to the longest side of the prayer rug 3, while the width
may correspond to the second longest side of the prayer rug 3. The prayer rug 3 may
be configured for determining and/or measuring a progression in prayer of a user.
[0244] A progression in prayer may be understood to comprise data indicating how far along
in a prayer is the user. For example, a prayer may require the user to bow and stand
up and repeat the steps of bowing and standing up 5 times. The prayer rug 3 may then
be of advantage in determining, for example, how many times the user has already bowed.
[0245] The prayer rug 3 may comprise one or more sensors 421, 4421, 4441, that may be used
to determine the progression in prayer. Each of the one or more sensors 421, 4421,
4441, may be configured to detect a change in a physical property. For example, any
of the one or more sensors 421, 4421, 4441, may comprise a pressure sensor that may
be configured to detect a change in pressure. Alternatively, or additionally, any
of the one or more sensors 421, 4421, 4441, may, for example, comprise a proximity
sensor that may detect reflected radiation corresponding to emitted electromagnetic
radiation and that may be configured to detect a change in the reflected radiation.
Further exemplarily, any of the one or more sensors 421, 4421, 4441, may comprise
a temperature sensor configured to detect a change in temperature. Any other suitable
sensor may be used.
[0246] Preferably, the prayer rug 3 comprises a plurality of sensors 421, 4421, 4441. As
depicted in Figure 1, the plurality of sensors 421, 4421, 4441, may comprise a plurality
of groups of sensors. The plurality of groups may comprise a first group of sensors
42, comprising at least one sensor 421, and a second group of sensors 44, comprising
at least one sensor 4421/4441. The second group 44 may preferably comprise a plurality
of sensors 4421, 4441. The plurality of sensors 4421, 4441 may comprise a plurality
of sub-groups of sensors, such as two sub-groups. As depicted in Figure 1, the second
group 44 may comprise a first sub-group 442 and a second sub-groups 444 of one or
more sensors.
[0247] As further depicted in Figure 1, the first group 42 of sensors and the second group
44 of sensors may be displaced with respect to each other along a dimension significantly
parallel to a length of the prayer rug 3. In this regard, the displacement of the
groups/sub-groups may be defined as the displacement of centroids of each of the groups/sub-groups.
[0248] Further, in some embodiments, a third group 46 of sensors may also be used. The third
group 46 of sensors may also be displaced with respect to the first group 42 and the
second group 44 of sensors. The third group 46 of sensors may be of particular advantage
in detecting a change in physical property caused by the feet of a user. The third
group 46 may also comprise a plurality of, particularly two, sub-groups of sensors,
displaced with respect to each other along a dimension significantly parallel to the
width of the prayer rug 3.
[0249] The first sub-group 442 and the second sub-group 444 may be displaced with respect
to each other along a dimension significantly parallel to a width of the prayer rug
3. In this regard, the displacement of the sub-groups may be defined as the displacement
of centroids of each of the sub-groups.
[0250] The first group 42 of sensors may comprise a plurality of sensors 421. Each of the
plurality of sensors 421 may, preferably, be significantly identical to any other
of the plurality of sensors 421. However, any of the plurality of sensors 421 may
also be different from any of the plurality of sensors 421. For example, a minimum
change in physical property detectable by a sensor 421 that lies closer to a centroid
of the first group 42 may be larger than a minimum change in physical property detectable
by a sensor 421 that lies farther away from a centroid of the first group 42. This
may be of advantage, for example, if the sensors 421 are expected to detect a higher
change in the physical property compared to sensors 421 further away.
[0251] The first sub-group 442 of sensors may comprise a plurality of sensors 4421. Each
of the plurality of sensors 4421 may, preferably, be significantly identical to any
other of the plurality of sensors 4421. However, any of the plurality of sensors 4421
may also be different from any of the plurality of sensors 4421. For example, the
sensors 4421 may be distributed based on an expected change in the physical property
to be detected by the sensors 4421 as described above for the sensors 421.
[0252] The second sub-group 444 of sensors may comprise a plurality of sensors 4441. Each
of the plurality of sensors 4441 may, preferably, be significantly identical to any
other of the plurality of sensors 4441. However, any of the plurality of sensors 4441
may also be different from any of the plurality of sensors 4421. For example, the
sensors 4441 may be distributed based on an expected change in the physical property
to be detected by the sensors 4441 as described above for the sensors 421.
[0253] Any of the plurality of sensors 4421, or 4441, may, preferably, be different from
any of the plurality of sensors 421. In other words, any of the plurality of sensors
in the first group 42 may, preferably, be different from any of the plurality of sensors
in the second group 44. In particular, a ratio of a minimum change in the physical
property detectable by a sensor 421 in the first group 42 to a minimum change in the
physical property detectable by a sensor 4421/4441 in the second group 44 may be between
0.001 and 1, preferably between 0.002 and 0.75, further preferably between 0.004 and
0.5. That is, generally, the sensors 421 in the first group 42 may be configured to
detect smaller changes in the physical property than the sensors 4421/4441 in the
second group 44. However, in some embodiments, any of the plurality of sensors in
the first group 42 may be significantly identical to any of the plurality of sensors
in the second group 44.
[0254] The prayer rug 3 may comprise a plurality of sections, such as 3 sections as depicted
in Figure 1. A first section may correspond to a section that may receive a forehead
of a user while praying. The first group of sensors 42 may be located in the first
section. A second section may correspond to a section that may receive a lower half
of the body of a user while praying. The second group of sensors 44 may be located
in the second section.
[0255] Within a section, the distribution of the sensors may be uniform, or, preferably,
nonuniform as depicted in Figure 1. For example, as depicted in Figure 1, along a
dimension significantly parallel to the width, an areal density of sensors may be
high in the center in the first section, and may be decreasing away from the center.
The center may correspond significantly to a location that may receive a forehead
of a user when praying.
[0256] For the second section, the areal density may be high at two locations displaced
with respect to each other along a dimension significantly parallel to the width,
with the areal density decreasing radially outward from the two locations, for example,
as depicted in Figure 2. The two locations may correspond significantly to locations
that may receive the feet and/or knees of a user when praying.
[0257] The prayer rug 3 may further comprise a display 10. The display 10 may be configured
to display data relating to the progression in prayer of a user. Exemplary data that
may be displayed will be described further below.
[0258] The prayer rug 3 may further comprise an electronics housing 20 that may comprise
one or more electronic components. For example, the prayer rug 3 may comprise a data
processing unit housed in the electronics housing 20. The data processing unit may
be configured to receive data related to the detected change in physical property
from any of the plurality of sensors 421, 4421, 4441.
[0259] The data processing unit may be further configured to process the data received from
any of the plurality of sensors 421, 4421, 4441. Exemplary analyses are described
below.
[0260] The data processing unit may be configured to send data to the display 10.
[0261] The prayer rug 3 may comprise a communication unit housed within the electronics
housing 20. The communication unit may be configured to communicate with the external
device 2. Further, the communication unit may be configured to communicate with the
data processing unit.
[0262] The prayer rug 3 may comprise a speaker housed within the electronics housing 20.
The speaker may be used to play audio that may correspond, for example, to a prayer
or other religious recitations. Alternatively, or additionally, the speaker may play
audio relating to the progression in prayer of a user. The speaker may be configured
to receive playable and/or control data from the data processing unit.
[0263] The prayer rug 3 may comprise a memory unit housed within the electronics housing
20. The memory unit may be configured to communicate with the data processing unit.
The memory unit may be configured to store, for example, a prayer that may be played
by means of the speaker. In particular, the communication unit, the data processing
unit, and the memory unit may be used together to download prayers and/or a prayer
schedule (as described further below) from the external device 2 on to the prayer
rug 3.
[0264] The prayer rug 3 may comprise a slot to receive a memory card, a USB stick, a data
cable, or, generally, data from any suitable data storage device housed within the
electronics housing 20. Exemplary data that may be received comprise a prayer, a sermon,
an audio track, or any other suitable audio.
[0265] The prayer rug 3 may comprise a microphone housed within the electronics housing
20. The microphone may be configured to communicate with the data processing unit.
The microphone may be of advantage for any of voice recognition, voice commands, and
assessment of user recitations. The data processing unit may be configured appropriately
for processing data captured by the microphone.
[0266] The prayer rug 3 may comprise a source of energy such as a battery housed within
the electronics housing 20. The battery may comprise a rechargeable battery. The electronics
housing 20 may be configured to allow connecting the battery to a power grid for recharging
the battery. Alternatively, or additionally, the battery may be configured to be recharged
by the movements of a user during prayer. This may be achieved, for example, by using
piezoelectric sensors 421, 4421, 4441, and using the electrical energy generated by
the change in pressure on the sensors 421, 4421, 4441 to charge a capacitor of the
battery.
[0267] Figure 1 further depicts elements 32 and 34 that may be of advantage in folding the
prayer rug 3. For example, any of the elements 32 and 34 may comprise compressed foam.
Alternatively, or additionally, any of the elements 32 and 34 may comprise zipping
sections allowing the different parts of the prayer rug 3 to be zipped together, when
in use. Generally, it may be understood that any of the elements 32 and 34 may comprise
significantly complementary sections that may be used to separate and join different
parts of the prayer rug 3.
[0268] Figure 2a depicts typical data 100 recorded by any sensor 421 in the first group
42 when the prayer rug 3 is in operation. Figure 2b depicts typical data 110 recorded
by any sensor 4421, 4441 in the second group 44 when the prayer rug 3 is in operation.
The y-axis depicts the detected change in physical property, while the x-axis depicts
time. In the following, the configuration of any one of the sensors 421 and any one
of the sensors 4421, 4441 will be described. Thus, whenever reference is made to "the
sensor" any one of the sensors 421, 4421, or 4441 is meant.
[0269] The sensor 421 may be configured to determine if the detected change in the physical
property exceeds a first threshold 102. The sensor 4421, 4441 may be configured to
determine if the detected change in the physical property exceeds a second threshold
112. Note that the first threshold 102, and the second threshold 112, may be greater
than or at least equal to the minimum change in property detectable by the sensor
421, 4421, or 4441. Further, the first threshold 102 may, preferably, be lower than
the second threshold 112. For example, a ratio of the first threshold 102 and the
second threshold 112 may be between 0.001 and 1, preferably between 0.002 and 0.75,
further preferably between 0.004 and 0.5.
[0270] The data processing unit may be configured to determine a number of times the detected
change in the physical property detected by the sensor 421 exceeds the first threshold
102. For example, the data processing unit may increment a counter up from a default
value, every time an up-crossing of the detected change, as depicted by the dashed
line 101, is detected to carry out this determination.
[0271] An up-crossing 101/111, or a down-crossing 103/113, may be determined by comparing
a current detected change in the physical property to a previous detected change in
the physical property. If the current detected change is greater than the threshold
102/112, and the previous detected change was lesser than the threshold 102/112, an
up-crossing may be detected. If the current detected change is lesser than the threshold
102/112, and the previous detected change was greater than the threshold 102/112,
an up-crossing may be detected. The data processing unit may be appropriately configured
to carry out these determinations. In particular, the data processing unit may be
configured to at least store the value of the previous detected change in the physical
property.
[0272] The data processing unit may be configured to send the value of the counter to the
display 10. Alternatively, or additionally, the data processing unit may be configured
to send the value of the counter to the speaker.
[0273] Further, the data processing unit may be configured to determine if the change in
the physical property detected by the sensor 4421, 4441, or, generally, a sensor in
the second group 44, exceeds the second threshold 112. This may be determined by comparing
the detected value of the change in the physical property to the second threshold
112.
[0274] The data processing unit may be further configured to determine a number of times
the detected change in the physical property detected by the sensor 421 exceeds the
first threshold 102 at significantly the same time as the change in the physical property
detected by the sensor 4421, 4441, or, generally, a sensor in the second group 44,
exceeds the second threshold 112. This number may correspond to the forehead being
placed on the prayer rug 3 at significantly the same time as the feet/knees are being
placed on the prayer rug 3, allowing a prostrate position of a user to be detected.
The progression in prayer may be indicated by the number of times the prostrate position
is detected.
[0275] For example, the data processing unit may increment a counter up from a default value,
every time an up-crossing of the detected change, as depicted by the dashed line 101,
is detected at significantly the same time as the change in the physical property
detected by the sensor 4421, 4441, or, generally, a sensor in the second group 44,
exceeds the second threshold 112 to carry out this determination. The data processing
unit may be configured to send the value of the counter to the display 10. Alternatively,
or additionally, the data processing unit may be configured to send the value of the
counter to the speaker.
[0276] The data processing unit may be further configured to determine a time elapsed since
the detected change in the physical property last exceeded the first threshold 102
and the second threshold 112 respectively. Note that this may generally comprise determining
a time elapsed since the last up-crossing of the detected change in physical property,
as depicted by the lines 101 and 111, or determining a time elapsed since the last
down-crossing of the detected change in physical property, as depicted by the lines
103 and 113. Preferably, however, only the time elapsed since the last down-crossing
103, 113 may be determined.
[0277] For example, a timer may be reset every time an up-crossing (101, 111) or a down-crossing
(103, 113) is encountered and its value stored before the reset.
[0278] The data processing unit may be configured to set the counter to the default value
when the time elapsed since the detected change in the physical property last exceeded
the first threshold 102 exceeds a first temporal threshold.
[0279] Alternatively, or additionally, the data processing unit may be configured to set
the counter to the default value when the time elapsed since the detected change in
the physical property last exceeded the second threshold 112 exceeds a second temporal
threshold.
[0280] The first temporal threshold may be greater than 40 minutes, preferably greater than
70 minutes, further preferably greater than 100 minutes. The second temporal threshold
may be greater than 30 minutes, preferably greater than 60 minutes, further preferably
greater than 90 minutes.
[0281] The data processing unit may be further configured to send to the external device
data relating, at least in part, to the number of times the detected change in the
physical property detected by the sensor 421 exceeded the first threshold 102 at significantly
the same time as the change in the physical property detected by the sensor 4421,
4441, or, generally, a sensor in the second group 44, exceeded the second threshold
112. The data may be of advantage in tracking prayer sessions of a user, for example.
[0282] The external device may be further configured to determine a time elapsed since data
was last received from the prayer rug 3. This may be of advantage in alerting a user
about an upcoming prayer session based on a pre-defined schedule.
[0283] The external device may comprise a user interface that may allow a user to upload
data relating, for example, to prayers and/or to the pre-defined prayer schedule,
to the external device, that may then be transferred to the memory unit of the prayer
rug 3. For example, the external device may comprise an app that may allow the user
to upload the data.
[0284] Overall, embodiments of the present technology aim to provide a prayer rug, an external
device, a system comprising the prayer rug and the external device, and a method for
determining the progression in prayer of a user that may be more efficient and robust,
and that may provide insights into the praying behavior of the user.
[0285] While in the above, a preferred embodiment has been described with reference to the
accompanying drawings, the skilled person will understand that this embodiment was
provided for illustrative purpose only and should by no means be construed to limit
the scope of the present invention, which is defined by the claims.
[0286] Whenever a relative term, such as "about", "substantially" or "approximately" is
used in this specification, such a term should also be construed to also include the
exact term. That is, e.g., "substantially straight" should be construed to also include
"(exactly) straight".
[0287] Whenever steps were recited in the above or also in the appended claims, it should
be noted that the order in which the steps are recited in this text may be accidental.
That is, unless otherwise specified or unless clear to the skilled person, the order
in which steps are recited may be accidental. That is, when the present document states,
e.g., that a method comprises steps (A) and (B), this does not necessarily mean that
step (A) precedes step (B), but it is also possible that step (A) is performed (at
least partly) simultaneously with step (B) or that step (B) precedes step (A). Furthermore,
when a step (X) is said to precede another step (Z), this does not imply that there
is no step between steps (X) and (Z). That is, step (X) preceding step (Z) encompasses
the situation that step (X) is performed directly before step (Z), but also the situation
that (X) is performed before one or more steps (Y1), ..., followed by step (Z). Corresponding
considerations apply when terms like "after" or "before" are used.
