Abstract
A computing device has a digitizer control module configured to monitor signals received by receive electrodes and to detect in the monitored signals a signal from a second touch display of a second computing device in physical proximity to the computing device. The digitizer control module is configured to determine one or more locations on the first touch display at which the signals from the second touch display are received. A processor in the computing device is configured to compute a relative position of the second touch display with respect to the first touch display on the basis of the determined locations, and to use the computed relative position to treat the first touch display and the second touch display as a combined touch display.
Claims20
A computing device comprising:
- a first touch display having a digitizer panel comprising at least a plurality of receive electrodes;
- a digitizer control module configured to monitor signals received by the receive electrodes and to detect in the monitored signals a signal from a second touch display of a second computing device in physical proximity to the computing device;
- the digitizer control module configured to determine one or more locations on the first touch display at which the signal from the second touch display are received, and to measure a strength of the signal from the second touch display;
- a processor configured to compute a relative position of the second touch display with respect to the first touch display based on the determined locations and the strength of the signal received from the second touch display, the processor configured to provide, to a user, feedback that indicates a presence of a misalignment between the first and second touch displays.
A method performed by a computing device comprising:
- monitoring signals received by receive electrodes in a digitizer panel of a first touch display of the computing device;
- detecting in the monitored signals a signal from a second touch display of a second computing device in physical proximity to the computing device;
- determining one or more locations on the first touch display at which the signals from the second touch display are received and measuring a strength of the signals from the second touch display;
- computing a relative position of the second touch display with respect to the first touch display based on the determined locations and the strength of the signals received from the second touch display;
- and
- providing, to a user, feedback that indicates a presence of a misalignment between the first and second touch displays.
A computing device comprising:
- a first touch display having a digitizer comprising at least a plurality of receive electrodes;
- a digitizer control module configured to monitor signals received by the receive electrodes and to detect a signal from a second touch display of a second computing device;
- the digitizer control module configured to determine one or more locations on the first touch display at which the signals from the second touch display are received, and to measure a strength of the signals;
- a processor configured to compute a relative position of the second touch display with respect to the first touch display based on the determined locations and the strength of the signals, the processor configured to compare the computed relative position with a target relative position and to provide feedback to a user upon a difference between the computed relative position and the target relative position being above a threshold, wherein the feedback indicates a presence or magnitude, or both, of the difference.
