Abstract

A flexible pointing device. The device consists of an elastic gel, a sensor, and a communication module, is used for pointing a cursor on a computer display, and has the following features: the elastic gel has a volume sufficient to hold the palm and wrist of a user, and the sensor is distributed at a position close to the center of the palm when the user uses the pointing device; the sensor detects the direction, velocity and distance of movement of the top of the elastic gel with respect to the base; the communication module is used for sending events of the direction, velocity and distance of movement to a computer. Therefore, the occurrence of carpal tunnel syndrome can be reduced.

Description

Flexible positioning device

Field of invention

The present invention relates to a flexible positioning device, and in particular to a positioning device made of an elastic gel.

Background technique

The most common and commonly used pointing device, of course, is the mouse. However, long-term high-intensity use of the mouse may result in a "mouse hand", the "Carpal Tunnel Syndrome" (CTS), which refers to the median nerve of the human body and the blood vessels entering the hand, which are oppressed at the carpal tunnel. The symptoms that are produced.

The carpal tunnel, as its name suggests, is a pipe in the wrist. It is like a subway tunnel that runs through our wrists. Eight carpal bones form the foundation and rails. The transverse ligament of the wrist forms a subway canopy with 10 tracks in the middle. 9 tendons and 1 median nerve. The space of the carpal tunnel is small, the tissue is tough, and it is difficult to release when the pressure inside the tube increases. We know that tendons have good "resistance" and nerves are the most vulnerable.

When the pressure in the carpal tunnel rises and the median nerve is damaged, the first thing that appears is sensory dysfunction. For example, the "three and a half fingers" of the median nerve are numb, painful, inflexible, etc. Some people sleep at night. Will be awakened, awakened, occasionally forearm, elbows, shoulders will also be dull pain; wrist pain, weakness, repeated pains in the wrist after bending inward, need to pick up hands to ease. If left unchecked at this time, the situation will continue to increase until the feeling of the big fish muscles diminishes and shrinks, and the finger strength weakens.

Summary of invention

Use the wrist pad when using the mouse to relieve wrist fatigue. However, a better way is to use a positioning device made of elastic gel. The invention provides a flexible positioning device:

·The main material is made of elastic gel with sensor and communication module

·The elastic gel is enough to hold the palm and wrist of the user

· The sensor is distributed close to the palm of the user when using the positioning device

Sensor detects the direction, velocity and distance of the top of the elastic gel relative to the base

· The communication module sends the top of the elastic gel relative to the base movement direction, speed and distance to the computer

However, it is to be understood that the invention is not intended to be limited or limited by the scope of the invention, and the invention disclosed herein The skilled artisan includes significant improvements and modifications thereto.

Detailed ways

The invention will now be described more fully hereinafter. However, the invention may be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. The present invention is intended to be thorough and complete, and the scope of the invention will be fully conveyed by those skilled in the art.

It will be appreciated that various changes can be made in the function and arrangement of the elements without departing from the spirit and scope of the invention. Thus, embodiments are examples or implementations of the invention, not the only implementation. The appearances of "one embodiment", "an embodiment" or "an embodiment" are not necessarily referring to the same embodiment. Although various features of the invention may be described in the context of a single embodiment, the features may be provided separately or in any suitable combination. Conversely, although the invention may be described herein in the context of a separate embodiment, the invention may be practiced in a single embodiment or any combination of the embodiments.

All terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, unless otherwise defined. It will be further understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the related art and the present disclosure, and will not be construed as idealized or excessive. Formal meaning, unless explicitly defined in this article.

Reference Terms such as "Left", "Right", "Top", "Bottom", "Front" and "After" are intended to be used in the practice of the present invention in relation to the particular features, structures or elements in the depicted embodiments. example. Obviously, this directional term for the actual use of the device has no specific meaning, as the device can be used by the user or multiple users in multiple directions.

We can design an algorithm based on the direction and speed of the top of the elastic gel relative to the base, just like the mouse detects its moving direction relative to the desktop, and then calculates the moving distance of the cursor. However, when the mouse is over or near the edge of the mouse pad, we will raise the mouse and put it back to the starting position. The same is true for touchpads, or gestures on touchscreens, with a similar "reset" requirement. Obviously you can't lift the elastic gel and put it back to the starting position. That is just a large soft mouse that does not solve the problem of carpal tunnel syndrome (CTS).

In contrast, the embodiment of the present invention allows the elastic gel to naturally return to the starting position by lifting the palm. At this time, the cursor movement algorithm ignores the movement direction and speed of the top of the elastic gel relative to the base, and realizes the function of "reset".

The elastic gel of the embodiment of the present invention is fixed to the table top based on its own weight or an auxiliary means such as a bottom suction cup. The positioning of the cursor is achieved by the movement of different parts of the body, rather than detecting the movement of the cursor relative to the desktop.

Various changes and modifications of the claims and the description of the present invention are still within the scope of the claimed invention. Moreover, each of the embodiments and claims does not necessarily include all of the advantages or features disclosed.
