Abstract
A computer device with a sensor subsystem for detecting off-surface objects, that carries out continued processing of the position and shape of objects detected in the vicinity of the device, associates these positions and shapes with predetermined gesture states, determines if the object is transitioning between gesture states and provides feedback based on the determined transition between the gesture states.
Claims18
A computing device, comprising:
- a display;
- a sensor subsystem for detecting off-surface objects;
- memory having instructions stored on it which when run on a processor, causes the processor to perform the steps of:
- detecting an off-surface object using the sensor subsystem;
- determining a position and a shape of said detected off-surface object;
- matching the determined position with a set of reference zones and the determined shape with a set of reference poses to thereby determine a gesture state;
- detecting changes in the determined position and shape using the sensor subsystem;
- matching said changes in the determined position with transitions between said reference zones and matching said changes in determined shapes with transitions between said reference poses to thereby determine a transition between gesture states;
- and,
- instructing a user interface to provide feedback based on the determined transition between gesture states.
The computing device of any preceding claim, wherein the feedback is a continuous feedback.
A computer-implemented method, for operating a computing device comprising a display, sensor sub system, processor and memory, comprising the steps of:
- detecting an off-surface object using the sensor subsystem;
- determining a position and a shape of said detected off-surface object;
- matching the determined position with a set of reference zones and the determined shape with a set of reference poses to thereby determine a gesture state;
- detecting changes in the determined position and shape using the sensor subsystem;
- matching said changes in the determined position with transitions between said reference zones and matching said changes in determined shapes with transitions between said reference poses to thereby determine a transition between gesture states;
- and,
- instructing a user interface to provide feedback based on the determined transition between gesture states.
A computing device, comprising:
- a display;
- a sensor subsystem for detecting off-surface objects;
- a means for detecting user input;
- memory having instructions stored on it which when run on a processor, causes the processor to perform the steps of:

- determining a position and a shape of said detected off-surface object;
- matching the determined position with a set of reference zones and the determined shape with a set of reference poses to thereby determine a gesture state;
- setting the sensor subsystem to a powered-on state when the means for detecting a user input has detected a predetermined user input.
