Abstract

Current computer mice use a multitude of movement-detection methods, but all require precise movements of the fingers or hands, as well as a restrictive posture of the hand. The suggested invention is a new computer mouse that uses a high-definition pressure sensitive surface for the detection of movement.

Minimal movement input device using a high definition pressure sensitive surface

Current computer mice use a multitude of movement-detection methods, but all require precise movements of the fingers or hands, as well as a restrictive posture of the hand. These are both uncomfortable and are known to cause medical problems such as Repetitive Strain Injury (RSI). Furthermore, most (if not all) computer mice, being planar devices, allow for two-dimentional movements.

  A better solution to the computer mouse would not be as restrictive in movement types and postures and would allow for a whole spectrum of additional movements, both in two dimensions and in three dimensions.

  The suggested solution is a new computer mouse that uses a high-definition pressure sensitive surface for the detection of movement. From a user's perspective, the mouse is a pad similar to a simple mouse pad. Unlike with other mice, the user is not restricted to place the hand in any particular position or posture. The movements required by the mouse are minimal, typically less than 5mm. Additional functionality is offered by additional movement types and additional uses possible by such hardware (see below).

  Thus, the proposed solution solves three of the problems of current mice and offers additional functionality compared to current models.

Possible competitors are:

1. Fingerworks (http://www.fingerworks.com): Their product is pressure pad which identifies gestures for generating mouse movements. However, their product only identifies large movements and functionally only basic mouse movements are allowed.
2. Tactex (http://www.tactex.com) : This company has a patent on biometric identification by measuring the physical properties of a hand placed on a pressure sensor.
3. Compac spring-type mouse: http://www.dealtime.com/xPF-Compaq_Magellan_Space_3D_299390_B21

  From a user's point of view, the mouse is similar to current mouse pads. A users can place a hand on the pad in any position or posture desired. Movements needed to perform mouse functions are typically less than 5mm. Possible movement types are:

1. Simple planar movements.
2. Click and double click, by pressing any of the fingers on the pad. Up to five mouse buttons can be emulated in this way.
3. Click and drag: The hand is moved while one of the fingers is slightly depressed to the pad.
4. Three dimensional movements, by pressing or releasing the whole hand from the surface of the mouse.
5. Rotation, through a rotation of the pal...
