Abstract
A system and method for providing a touch control system are disclosed. In one aspect a touch screen interface on a mechanical keyboard is disclosed. A touch sensing area on a keyboard having mechanical key mechanisms also provides a touch sensing surface. Touch position on the keyboard is detected and used to control a user interface. Unique touch sensing systems are also disclosed.
Claims15
A position sensing system, comprising:
- one or more IR LEDs configured about at least a portion of a position sensing region;
- a plurality of IR detectors configured along at least one edge of the position sensing region, wherein at least some of the IR detectors are configured to be illuminated by plural LED beams when active;
- and
- a control system which sequentially pulses the one or more IR LEDs, wherein at least some of the IR detectors are sequentially illuminated by plural LED beams, wherein the control system determines the detector signal strength at said detectors for a timing window for an LED pulse, correlates the time of the detector window signal to a specific LED beam, and stores a series of time correlated detected signal strengths.

An interactive touch sensing system and portable computer system, comprising:
- a touch sensing system configured to detect finger touch position in a generally planar virtual touch sensing area adjacent to a movable physical surface;
- a reference feature configured on or attached to the physical surface such that it moves with the physical surface;
- and
- a portable computer system including a display, the computer system receiving the finger touch position information and providing control of a graphical user interface displayed on the display in response to the touch position information;
- the interactive system further comprising a camera configured on or attached to the display and movable relative to the virtual touch sensing area, the camera configured to image the reference feature and virtual touch sensing area, and a processor which implements an algorithm using image data from the camera to detect movement of the feature relative to the camera and adjust virtual touch control using the detected relative movement.
2 more elements
A method for providing touch control of a portable computer system from a virtual finger position sensing area, comprising:
- sensing finger position corresponding to a virtual touch in a movable generally planar virtual touch sensing area;
- providing a physical reference feature fixed relative to the virtual touch sensing area;
- imaging the reference feature and some or all of the virtual touch sensing area using one or more cameras movable relative to the reference feature and sensing area;
- controlling a graphical user interface displayed in a portable computer system in response to the detected virtual touch;
- and
- adjusting the touch control in response to movement of the detected reference feature position relative to the one or more cameras.
