[0025] Persons skilled in the art should be noted that the display unit 23 of the intelligent wearable device 2 is a display screen having single screen (light-emitted diode, LED) or multiple screen LEDs, or different display devices. In other words, the input statuses are displayed on single screen LED or the text messages are inputted to the different multiple screen LEDs by a switching mode between the multiple screen LEDs.

[0026] FIG. 1 is an illustrative block diagram of a wireless input system based on an intra-body communication according to one preferred embodiment of the present invention. Persons skilled in the art should be noted that the units within the wireless keyboard 1 and the intelligent wearable device 2 can be modified based on different application fields.

[0027] The wireless keyboard 1 is a wireless keyboard which is clicked by the hands of the user. The wireless keyboard 1 serves as an input function. When the wireless keyboard 1 detects that the user hits the keys of the keyboard by the hands, the wireless keyboard 1 records and stores the keying code information corresponding to the keystrokes, and the intra-body communication unit is installed in the wireless keyboard 1 to transmit the keying code information and the keyboard type information of the wireless keyboard 1 via the intra-body communication technology.

[0028] In one preferred embodiment, the wireless keyboard 1 further includes the following units.

[0029] A click-detecting unit 121 is configured to detect whether the user clicks the wireless keyboard 1 by the hand. If the click-detecting unit 121 does not successfully detect that the user clicks the wireless keyboard 1 by the hand, the click-detecting unit 121 continuously detect the click operations of the user. If the click-detecting unit 121 successfully detects that the user clicks the wireless keyboard 1 by the hand, the wireless keyboard 1 transmits the received instructions, which correspond to the keying code information and the keyboard type information of the wireless keyboard 1, to the intelligent wearable device 2 via the human body, and the intra-body communication unit of the transmitting terminal 11 and the intra-body communication unit of the receiving terminal 21.

The receiving and determining unit 221 of the intelligent watch analyzes the received information and determines whether the keyboard type information, which is received from the intra-body communication unit of the receiving terminal 21, corresponds to the wireless board 1 clicked by the user.

[0036] A determination unit 222 is configured to determine whether the intelligent wearable device 2 is in an input status when the keyboard type information corresponds to the wireless board 1 clicked by the user.

[0037] When the receiving and determining unit 221 of the intelligent wearable device 2 (e.g., an intelligent watch) determines that the received the keyboard type information corresponds to the wireless board 1 clicked by the user, the determination unit 222 determines whether the intelligent wearable device 2 is in the input status. In other words, it is determined whether the intelligent wearable device 2, such as an intelligent watch, starts the application and control functions to input text messages, such as a scene-chatting function, a scene-searching function and a text-recording scene.

[0038] An input method unit 223 is configured to acquire the keying code information and maps the acquired keying code information to the simulated keying code information when the intelligent wearable device 2 is in the input status.

[0039] When the intelligent wearable device 2, such as an intelligent watch, is in the input status, the input method unit 223 acquires the keying code information and maps the acquired keying code information to the simulated keyboard keying code information within the intelligent watch.

[0040] A searching and input unit 224 is configured to start an input method mode of the intelligent wearable device 2 based on the simulated keyboard keying code information to search the corresponding text messages for input.

[0041] Based on the simulated keyboard keying code information which are mapped to the keying code information by the wireless keyboard 1, the input method mode of the intelligent wearable device 2 starts to search the corresponding text messages for input.

[0042] It should be noted that the functions of the units in the present disclosure are not absolute. One or more functions or a portion of a function within the units in the claims can be implemented by one unit or more units. Furthermore, two or more units can be combined together, or one function can be implemented by two units or more units.
