Finger worn and operated input device and method of use
First Claim
1. A method for providing finger movement and tap gesture input to a computer or instrument which allows a user to control the cursor movement on a display connected to computer or instrument, said method comprising:
- touching thumb tip with index fingertip or any of the other three fingertips of the same hand by curling index finger or any of the other finger and thumb together and asserting pressure between the contacted said fingertips;
Twiddling said fingertip and thumb tip each other or just gliding said fingertip on said thumb tip;
sensing the relative movement and pressure between said fingertip and thumb tip with a two dimension position sensor in conjunction with another pressure sensor or a three dimension position sensor worn on said thumb tip;
mapping the said relative movement to said cursor movement based on said pressure or the third dimension variable from said three dimension sensor;
tapping said fingertip with said thumb tip to interactive with said display such as selection and executive command. sensing the tapping gestures between said fingertip and thumb tip by said sensor.

Abstract
The present invention provides a finger worn and finger operated input device for personal computer, workstation or computer based instrumentation. The finger operated method in the present invention eliminated the necessary of a stationary support table or pad. The special operation method of the device also eliminated the affect from tremor and movement of user'"'"'s hand. Therefore user can operate the device at any comfortable posture. A method for dynamically adjusting the mapping sensitivity from the device to cursor movement based on the touch pressure between the fingertips ensures that user can achieve large and small cursor movement on the same small sensor area. user can friendly operates the said device with natural finger movement and gestures to help minimize strain on neck, shoulder, hand and wrist muscles, thereby alleviating the possibility of Repetitive Strain Injury (RSI) and Carpal Tunnel Syndrome (CTS) which normally associated with desktop mouse devices. The present invention further provide ergonomic peripheral input system for computer by in conjunction use with a virtual keyboard on computer screen. The present invention also has advantage in other special applications such as for projection presentations.

4. A method to wear point device sensor on finger and operated by finger to eliminate the need of the stationary support or handheld and to eliminate the tremor of hand of user, comprising:
-
a three dimension position sensor or two dimension sensor in conjunction with another pressure sensor, worn securely on said thumb with sensing area coincident to thumb tip and sensing area face out so as to permit said fingertip moving and taping on said sensor just like on said thumb fingerprint area;
said sensor to sense said relative movement in two orthogonal directions which determined by the sensor alignment and pressure between touched finger tips;
operating said sensor with index fingertip or middle fingertip by curling index finger or middle finger and thumb together. sensor signals considered as valid signals only when the said finger touched said sensor worn on said thumb so mistake signals or tremor can be eliminated.
