DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS OF THE INVENTION
[0013] The Figures schematically illustrate apparatus 100 comprising: means 101 for detecting
a force applied to the apparatus; and means 102 for sliding the apparatus along another
surface 103 separate of the apparatus 100.
[0014] Various non-limiting embodiments of the present invention as defined in the appended
claims, seek to provide an apparatus, system and computer program for performing and
monitoring leg exercises.
[0015] The means for detecting a weight applied to the apparatus comprises a force or pressure
sensor. The means is configured to detect and measure a force applied to the apparatus,
for example such as a user placing his/her heel on top of the apparatus.
[0016] The means for sliding the apparatus comprises a sliding surface which, when in use,
is in contact with the another surface separate of the apparatus. The means for sliding
may be configured, such as via its shape and material, so as to enable and or facilitate
the apparatus sliding along the another surface. For example a user resting his/her
heel on the apparatus and moving his/her leg, e.g. bending his/her knee, so as to
cause the apparatus to the slide along the another surface.
[0017] Certain embodiments of the invention provide an improved apparatus that can facilitate
the performance of various limb exercises as well as monitor the same, thereby aiding
rehabilitation and training/prehabilitation of a user's limb. Limb exercises may include,
for example, 'straight leg lifts', 'knee bends' and 'leg swings'.
[0018] The apparatus comprises means for outputting a signal from the means for detecting
a force. The output means may be audio, visual or haptic output means to provide user
feedback relating to the exercises being performed and monitored. Alternatively the
output means may comprise means for transmitting signals from the apparatus to a remote
device, i.e. so that audio, visual or haptic output means of the remote device might
be employed to provide user feedback, tracking of progress and recording use of the
apparatus.
DESCRIPTION
[0019] An example of embodiments of the invention will now be described with reference to
the Figures. Similar reference numerals are used in the Figures to designate similar
features. For clarity, all reference numerals are not necessarily displayed in all
figures.
[0020] In Figure 1, only the functional components that are necessary for describing the
operation of the device are discussed. Although embodiments of the apparatus are described
in terms of comprising various components, it should be understood that the components
may be embodied as or otherwise controlled by a corresponding processing element or
processor of the apparatus. In this regard, each of the components described below
may be one or more device, means or circuitry embodied in hardware, software or a
combination of hardware and software that is configured to perform the corresponding
functions of the respective components as described in greater detail below.
[0021] Figure 1 schematically illustrates an apparatus 100 according to an embodiment of
the invention. The apparatus comprises means 101 for detecting a force or load 101a
applied to the apparatus. The force may correspond to a weight of at least a portion
of a user's limb, such as a user's heel being placed upon / resting on an upper surface
of the apparatus. The means 101 for detecting the force is a force sensor.
[0022] In one embodiment the means comprises a capacitive sensor comprising two capacitive
plates configured such that a separation between the plates is proportional to a force
applied to the apparatus. I.e. such that a minimum plate separation distance is provided
when there is no force applied to the device. Accordingly, a detection that the load
has been removed from the apparatus is determined when the capacitive sensor indicates
a minimum plate separation.
[0023] The apparatus 100 also comprises, on its lower surface, a sliding surface 102 for
sliding the apparatus along another surface 103, wherein the another separate surface
is a surface separate of the apparatus. The sliding surface 102 is configured so as
to facilitate the apparatus to slide along, skid across or glide over the other surface,
thereby enabling translational movement of the apparatus along the surface 103 by
sliding/skidding/gliding of the apparatus 100 across the surface 103. The sliding
surface 102 may comprise a sliding surface, i.e. an external surface which, in use,
is in contact with the surface 103. The sliding surface comprises a part of an external
housing 104 of the device.
[0024] The sliding surface 102 may comprise a rim or edge portion 106 which, when in use,
is curved upwardly away from the surface 103. Furthermore, the sliding surface may
be substantially devoid of protrusions or recessions so as to avoid the apparatus
from snagging or catching on the surface 103 and to facilitate the apparatus's sliding
across the surface.
[0025] The sliding means 102 may be configured so as to have, for example, at least one
of: a streamline shape, a substantially convex cross-sectional shape, and a substantially
smooth surface. The sliding means may be substantially free from deformations and
perturbations and have a low surface roughness. The sliding means may be made of a
material that has a static and/or dynamic coefficient of friction with respect to
the separate surface of: less than 0.5, or preferably less than 0.2, or more preferably
less than 0.1 or yet more preferably less than 0.05.
[0026] The apparatus, on its upper surface, further comprises means 107 for coupling the
apparatus to at least a portion of a limb of a user (not shown) or for engaging the
apparatus with the limb portion. The limb portion may correspond to a leg or a heel
of a user (when with or without clothing/footwear). The coupling means 107 may comprise
an exterior surface having a substantially concave shape. Its cross-sectional shape
is substantially concave so as to form a depressed/recessed area with respect to the
circumferential rim portion 106 of the apparatus 100. The depressed area may be configured
in a shape complementary to the limb portion that is to be received, such as a heel
of a user, so that the limb portion can abut against or mate within the concave surface.
[0027] The depressed area may further comprise cushioning or a deformable material that
can mould/form around the shape of the limb portion to provide a secure and comfortable
nest for the limb portion. Furthermore, the depressed area may comprise a grip/non-slip
surface by which to engage with the limb portion and provide a form of frictional
coupling of the limb portion to the apparatus, such that the frictional force between
the limb portion and the coupling means 107 is greater than the frictional force between
the sliding means 102 and the surface 103. Advantageously, this means that when a
horizontal translational force is applied by the limb portion to the apparatus, the
limb portion stays attached to the apparatus and does not slide off, but instead the
apparatus slides across the surface, i.e. the apparatus is dragged across the surface
by the limb portion.
[0028] The apparatus may take on a substantially "saucer-like" shape with its concave surface
106 on the upper side of the apparatus opposite to the convex sliding surface 102
on the lower side.
[0029] Figures 2a and 2b schematically illustrate a use of embodiments of the invention,
in particular in facilitating the performance of 'knee bend' exercises.
[0030] As shown in Figure 2a, a user 201 is lying down on the surface 103. For example,
the user may be lying on the ground or on a bed, such that the surface may comprise,
for example, a carpet or other flooring material or bed sheets or other bedding material.
Initially, the user's upper leg 202, knee 203 and lower leg 204 are straight and the
apparatus 100 is placed beneath the user's heel 205 such that the apparatus' sliding
means 106 is in contact with the surface 103.
[0031] As shown in Figure 2b, when a user bends his/her knee 203 whilst keeping his/her
heel 205 within the coupling means 106, this act applies a translational horizontal
force to the apparatus via the user's heel. This causes the apparatus 100 to be dragged
towards the user, i.e. from initial position 206a to 206b. The apparatus slides/skids/glides
across the surface 103 via its sliding means 106 when dragged along by the user's
heel.
[0032] Figure 3 schematically illustrates an apparatus 100 according to a further embodiment
of the invention. This apparatus is similar to the one shown in Figure 1. However,
the apparatus further comprises output means 301. The output means receives signals
from the means for detecting a force 101 as well as one or more further sensors 302,
303 and 304. These additional sensors may measure movement, acceleration or orientation
and provide signals relating to the same to the output means 301. The sensors may
comprise, for example: accelerometers or gyroscopes.
[0033] The output means 301 provides one of more of: audio, visual or haptic output based
on the measurement signals from the sensors, for example via a speaker, display or
vibrator. For example, an output may be provided which is triggered in dependence
on a sensor signal to provide feedback to a user related to the exercises being performed,
such as horizontal movement of the apparatus during a knee bend or detection of a
straight leg lift as discussed below with respect to Figures 4a and 4b.
[0034] Alternatively, instead of providing: audio, visual or haptic output means within
the apparatus to provide feedback to a user, the output means may comprise a communication
interface for outputting sensor signals to a remote device (not shown), such as via
wired or wireless communication. The remote device may be any suitable device capable
of receiving sensor signals and providing an output related to the same, for example:
a portable hand held electronic device, a mobile phone, a tablet, a PDA, a laptop,
a PC, user programmable consumer electronic device or a server. The remote device
may have additional functions besides receiving and outputting information from the
apparatus. Advantageously, this leverages use of audio, visual or haptic output means
provided on such (ubiquitous) remote devices, which a user may well already be in
possession of. Also, off loading user feedback output functionality to a remote device
saves on the costs of components, complexity of manufacturing and space/size of the
apparatus which would otherwise be required to providing such features and functionality
within the apparatus itself.
[0035] The output means 301 may comprise a communication interface and a transmitter, e.g.
configured for short range wireless communication, such as: Bluetooth ™ or infrared
IRDA. The output means could be configured for WLAN, Wi-Fi or any other suitable wireless
data transfer protocol.
[0036] The coupling means 106 for coupling the apparatus to a portion of a limb of a user
may further comprises securing means 305 to attach the apparatus to the limb portion.
The securing means may comprise any suitable means for releasably attaching the limb
portion to the apparatus, for example so as to enable the apparatus to remain coupled
to the user's limb portion even when the limb portion is raised off the ground. The
securing means may comprise a member such as a strap 305 which goes around the limb
portion and is secured to the apparatus at attachment points 306 and 307.
[0037] Figures 4a and 4b schematically illustrate a use of embodiments of the invention,
in particular in facilitating the detection and/or monitoring of 'straight leg lift'
exercises, wherein at least the entire lower leg is raised as a substantially straight
unit.
[0038] As shown in Figure 4a, the user 201 is lying down on the surface 103. Initially,
the user's upper leg 202, knee 203 and lower leg 204 are straight and the apparatus
100 is placed beneath the user's heel 205. The user's heel is resting on the apparatus
which itself is disposed on the surface. In this state, a downwards force 205' due
to the weight of the use's heel is applied to the apparatus. This is balanced by a
reaction force 103' in an upwards direction from the surface 103. The means 101 for
detecting a force applied to the apparatus detects the weight of the user's limb and
is thereby able to determine that the limb is resting on the apparatus.
[0039] As shown in Figure 4b, when the user raises his/her leg keeping it straight, a translational
vertical force is applied to his/her heel. This causes the weight of the heel 205'
to gradually be removed from the apparatus 100. When the forces 205' and 103' are
no longer detected the means for detecting a force applied to the apparatus determines
that the weight of the user's limb has been removed, the limb has been raised up and
is no longer resting on the apparatus.
[0040] A signal from the means for detecting a force can be wireless transmitted to a remote
device via output means 301. The remote device 401 is configured to receive the signal
from the apparatus 100 and generate an output based on the same so as to provide feedback
to a user that he has successfully performed a straight leg lift and raised his/her
leg up. Alternatively, where the apparatus comprises its own on board audio, visual
or haptic output means, this could be triggered, e.g. an aural, visual or haptic alert
could be emitted to provide feedback to the user informing the user that a straight
leg lift has been accomplished.
[0041] As shown in Figure 4b, if the user continues to raise his/her leg upwards, the apparatus,
which is attached to the user's limb portion via securing means 305, will be pulled
upwards along with the raised leg and heel, thereby lifting up the apparatus from
the surface 103 as shown with arrow 402. However, alternatively, where the apparatus
is provided with no such securing means (as per the embodiment of Figure 1) the user's
leg can be raised off the apparatus during a straight leg lift and the apparatus remains
on the surface 103. The means for detecting a force determines that the user's limb
portion has been lifted of the apparatus and transmits a signal to that effect to
the remote device to provide an output for user feedback.
[0042] Figures 5a and 5b schematically illustrate a use of embodiments of the invention,
in particular in detecting and/or monitoring of 'leg swing' exercises and the degree
of leg swing.
[0043] As shown in Figure 5a, the user 201 is standing upright with the user's upper leg
202, knee 203 and lower leg 204 all substantially straight and vertically aligned.
The apparatus 100 is placed beneath the user's heel 205. In addition to the apparatus
being secured to the user's heel, further additional sensors 501 and 502 separate
from and remote of the apparatus are attachable to the user's limb, such as at the
upper leg 202 and lower leg 204. These additional sensors measure and/or detect: at
least one of: movement, acceleration and orientation. The sensors may comprise: an
accelerometer, a gyroscope or a goniometers. Furthermore, the sensors are configured
to transmit signals related to their measurements to the remote device 401.
[0044] This system 500, comprising the apparatus 100 and the additional sensors 501 and
502, enables a determination and monitoring of a degree of swinging of the leg. Signals
relating to this are transmitted to the remote device which provides feedback, such
as visual feedback as shown in the figures, to the to the user.
[0045] In Figures 5a and 5b, additional sensors remote and external to the apparatus are
provided. However, it is to be appreciated that the sensors could instead be provided
internal of the apparatus as shown in Figure 3 with reference to sensors 302, 303
and 304, such that detecting and/or monitoring of leg swings can be effected with
the apparatus itself without the need of additional remote sensors.
[0046] Figure 6 schematically illustrates a block diagram of an embodiment of the apparatus
100. The apparatus 100 may take the form of a medical device or an exercise device.
The apparatus 100 comprises a controller such as a processor 601 and a memory 602
including computer program 603 comprising computer program instructions 604. The processor
may also comprise an output interface 605 via which data and/or commands are output
by the processor and an input interface 606 via which data and/or commands are input
to the processor.
[0047] Implementation of controller can be in hardware alone (a circuit), have certain aspects
in software including firmware alone or can be a combination of hardware and software
(including firmware). The computer program 603 may be stored on a computer readable
storage medium 607 (disk, memory etc).
[0048] The apparatus further comprises: one or more sensors 101, 302, 303 and 304, one or
more output means 301, 301 a-c. The output means 301 may comprise a transceiver configured
for wireless communication with a remote device (not shown). The output means 301
a-c may comprise audio, visual and haptic output means.
[0049] The computer program 603 comprises computer program instructions 604 that control
the operation of the apparatus 100 when loaded into the processor 601. The computer
program instructions provide the logic and routines that enables the apparatus to
cause the apparatus 100 at least to:
receive sensor measurements from the one of more sensors 101, 303, 304, 305; and
transmit signals related to the sensor measurements to a remote device.
[0050] Figure 7 schematically illustrates a flow chart 700 of a method according to at least
some examples of the disclosure. The blocks illustrated in Figure 7 may represent
steps in a method and/or sections of code in a computer program for the remote device,
i.e. so as to configure the remote device for use with the apparatus and control the
remote device to operate in a particular manner in response to receipt of information
from the apparatus.
[0051] In block 701, a signal is received by the remote device 401 from the apparatus 100.
In block 702, an output is generated at the remote device which is dependent upon
the received signal. The output may be an audio, visual or haptic output for providing
feedback to a user when performing leg exercises. Additionally, the received signals
relating to sensor measurements of the apparatus may be stored so as to track progress
of a user's rehabilitation/training. Furthermore, the sensor measurements may be sent
from the remote device to further devices/people, such a physiotherapists, doctors
or other medical practitioners.
[0052] The procedures described above may be embodied by computer program instructions.
In this regard, the computer program instructions which embody the procedures described
above may be stored by a memory storage of the remote device and performed by a processor
of the remote device.

by a combination of hardware and computer program instructions of a computer program.
These program instructions may be provided to one or more controllers or processors

program instructions for performing the specified functions. It will also be understood
that each block, and combinations of blocks, can be implemented by special purpose
hardware-based systems which perform the specified functions or steps, or combinations

[0055] In the description above, the wording 'couple' and 'communication' as well as their
derivatives mean operationally connected and in operational communication respectively.
It should be appreciated that any number or combination of intervening components
can exist (including no intervening components). For example, the user's heel being
coupled to the apparatus encompasses a coupling of the user's limb both with and without
socks and/or shoes on. The communication between the apparatus and the remote device
may be direct or indirect via other 3
rd party devices, such as a router.

or means that provide the functionality described above. The modules or means may
be implemented as hardware, or may be implemented as software or firmware to be performed
by a computer processor. In particular, in the case of firmware or software, embodiments
of the invention can be provided as a computer program product including a computer
readable storage structure embodying computer program code (i.e. the software or firmware)
thereon for performing by the computer processor.
[0057] Features described in the preceding description may be used in combinations other
than the combinations explicitly described. Although functions have been described
with reference to certain features, those functions may be performable by other features

that modifications to the examples given can be made without departing from the scope
of the invention as claimed. For example whilst embodiments have been described with
respect to a leg exercise/monitoring device, it will be appreciated that embodiments
