Abstract
Disclosed are a system and a method for rehabilitation exercise of hands. The system and the method help a device sense movements of the hands more accurately. The device for rehabilitation exercise of the hands comprising multiple sense parts that are located on each part of a user's hand, and configured to sense movements of the each part; and communication part configured to send movement data sensed by the multiple sense parts to an output device.
Core Innovation
The invention relates to a device for rehabilitation exercises of a user's hands. The device includes multiple sense parts configured to be located on parts of a hand and to sense movements of those parts, and the multiple sense parts send multiple pieces of movement data to an output device.
The multiple sense parts include at least one finger sense part on fingers, a back sense part on a back of the hand, and a wrist sense part on a wrist. Each sense part includes a movement sensing sensor and is configured to measure and generate first movement data, second movement data, and third movement data, respectively, and fixing tools fix the finger sense part, the back sense part, and the wrist sense part to corresponding portions of the parts.
The device further includes a communication part configured to send the multiple pieces of movement data to the output device. The output device includes a screen that displays a graphic object corresponding to the multiple pieces of movement data by using a correlation between the first movement data and the second movement data and a correlation between the second movement data and the third movement data.
Claims Coverage
The independent claim includes 4 inventive features: finger, back, and wrist sensing on a hand; fixing tools for those sense parts; communication of multiple movement data to an output device; and screen-based display of a graphic object derived from correlations among the movement data.
Finger, back, and wrist multiple sense parts for hand rehabilitation
A device for rehabilitation exercises of user's hands, including multiple sense parts configured to be located on parts of a hand and to sense movements of the parts, wherein the multiple sense parts include at least one finger sense part, a back sense part, and a wrist sense part, each including a movement sensing sensor configured to measure and generate first movement data, second movement data, and third movement data.
Fixing tools to fix sense parts on corresponding hand portions
The finger sense part, the back sense part, and the wrist sense part include fixing tools configured to fix the finger sense part, the back sense part, and the wrist sense part to corresponding portions of the parts.
Communication of multiple movement data to an output device
A communication part configured to send multiple pieces of movement data sensed by the multiple sense parts to an output device.
Screen display using correlations between finger-back and back-wrist movement data
The output device includes a screen and is configured to display, on the screen, a graphic object corresponding to the multiple pieces of movement data, wherein the graphic object is displayed by using a correlation between the first movement data and the second movement data and a correlation between the second movement data and the third movement data.
Correlating sensed movement with pre-stored reference movement data with an alarm signal
The device further outputs an alarm signal when movement data detected by multiple sensing parts does not match pre-stored reference movement data.
Specific movement sensor implementation using a 9-axis IMU
Each movement sensing sensor of the finger sense part, the back sense part, and the wrist sense part includes an IMU sensor configured as a 9-axis IMU sensor.
Overall, the claim coverage emphasizes a hand rehabilitation device with finger, back, and wrist sensing, communication of multiple movement data to a screen-based output, and a graphic object displayed based on correlations among finger-back and back-wrist movement data. Dependent claims further specify a 9-axis IMU implementation and an alarm signal based on comparison to pre-stored reference movement data.
Stated Advantages
Displays a graphic object on a screen corresponding to multiple pieces of movement data including first, second, and third movement data.
Displays the graphic object using correlations between finger movement data and back movement data and between back movement data and wrist movement data.
Outputs an alarm signal when sensed movement data does not match pre-stored reference movement data.
Documented Applications
Rehabilitation exercises of a user's hands using a hand-worn device with sense parts on fingers, the back of the hand, and the wrist.
