Abstract
Systems and methods may provide virtual and configurable touchscreens. The systems and methods may include a plurality of micro impulse radar (MIR) transceivers and logic to determine a location of an input object such as a finger or pointer based on signals from the plurality of MIR transceivers. The MIR transceivers may also create a virtual touchscreen in a plane coincident (adjacent) to or spaced apart from (offset) with respect to a display screen. The MIR transceivers may also map the location of the input object to a position on the display screen. In one example, the system uses triangulation to determine the location of the input object in a virtual plane that creates the virtual touchscreen.
Claims22
A system comprising:
- a display screen;
- a plurality of micro impulse radar (MIR) transceivers, wherein the MIR transceivers are disposed in a fixed position to transmit and receive MIR signals;
- and
- logic, implemented at least partly in fixed-functionality hardware, to,
- use triangulation to determine a location of an object based on signals from the plurality of MIR transceivers, and
- map the location of the object to a position on the display screen,
- wherein the logic is to determine one or more of a composition or a size of the object based on one or more of a timing of return signals associated with the MIR transceivers, a strength of return signals associated with the MIR transceivers or a frequency of transmitted signals associated with the MIR transceivers.
A method comprising:
- using triangulation to determine a location of an object based on signals from a plurality of micro impulse radar (MIR) transceivers, wherein the MIR transceivers are disposed in a fixed position to transmit and receive MIR signals;
- mapping the location of the object to a position on a display screen;
- and
- determining one or more of a composition or a size of the object based on one or more of a timing of return signals associated with the MIR transceivers, a strength of return signals associated with the MIR transceivers or a frequency of transmitted signals associated with the MIR transceivers.
An apparatus comprising:
- logic, implemented at least partly in one or more of configurable logic or fixed-functionality hardware, to,
- use triangulation to determine a location of an object based on signals from a plurality of micro impulse radar (MIR) transceivers, wherein the MIR transceivers are disposed in a fixed position to transmit and receive MIR signals,
- map the location of the object to a position on a display screen, and
- determine one or more of a composition or a size of the object based on one or more of a timing of return signals associated with the MIR transceivers, a strength of return signals associated with the MIR transceivers or a frequency of transmitted signals associated with the MIR transceivers.
At least one non-transitory computer readable storage medium comprising a set of instructions which, if executed by a computing device, cause the computing device to:
- use triangulation to determine a location of an object based on signals from a plurality of micro impulse radar (MIR) transceivers, wherein the MIR transceivers are disposed in a fixed position to transmit and receive MIR signals,
- map the location of the object to a position on a display screen, and
- determine one or more of a composition or a size of the object based on one or more of a timing of return signals associated with the MIR transceivers, a strength of return signals associated with the MIR transceivers or a frequency of transmitted signals associated with the MIR transceivers.
