A simple, accurate and inexpensive device pointing system using head tilt gesturing

Tech ID: 28877 / UC Case 2017-891-0

Brief Description

Current device pointing systems, which control the movement of cursors on screens, suffer from several drawbacks which often preclude their use by individuals with special needs or medical conditions. This UCI invention describes a simple, inexpensive “head mouse” that, in combination with proprietary software, tracks the position of the head relative to the body, allowing for full control of a pointing device.

Full Description

A pointing device, such as a computer mouse or laptop trackpad, is used to control the 2D movement of cursors on computer screens. Due to the fact that many such devices are controlled via hand gestures, they are not easily operated by those suffering from afflictions such as decreased motor control. UCI inventors, by simply tracking head gestures, have made available a prototype of a wireless pointing device that is simple, inexpensive, and comfortable to wear. Furthermore, this wearable device can also be implemented in medical rehabilitation applications, such as posture control.

Suggested uses

  • Motion tracking for device pointing, for use by computer operators
  • For use by individuals with medical conditions, who are unable to use other pointing devices
  • For the purpose of medical rehabilitation, e.g. posture control

Advantages

  • Current device pointing systems suffer from drawbacks, e.g. high costs, high processer requirement, immobility, calibration requirement, error accumulation, high overshoot, degradation adjacent to magnetic fields, etc.
  • This invention is a wearable setup that tracks movements of the head, i.e. head tilting gestures, and processes these gestures to suitably control a pointing device
  • Such an invention serves the unmet needs of individuals who cannot operate regular pointing devices such as mice or track pads

State Of Development

A functional prototype has already been built and tested with satisfactory results. Future plans include the improvement of mechanical design and the use of the Bluetooth Low Energy protocol for better mouse connectivity to computers. A prototype is being built for a competition in Taiwan, end-July 2017.
