  • Publication number: 20230377222
    Abstract: A remote computer sequentially detects positions of an indicator on a sensor surface at a predetermined sampling rate using an input sensor, and sequentially transmits pieces of report data including the positions to a host computer. A host computer detects a gesture based on a series of the pieces of report data received from the remote computer, generates one or more deformed images by imparting a deformation corresponding to contents and an amount that are indicated by the gesture, to one or more images, transmits the one or more deformed images to the remote computer, and performs cancelation processing that cancels generation of the one or more deformed images when one of the pieces of report data received from the remote computer includes an end report indicating that the indicator has been moved away from the sensor surface.
