More Information
Summary:The structure and devices described herein provide an improved digital eraser for a stylus. A stylus may have an eraser end that transmits an erase signal from an eraser antenna. A cover houses the eraser antenna and can be configured with varying geometry to selectively position the eraser antenna closer to, or further away from, a digitizer screen of a computing device when the cover is in contact with the digitizer screen. The computing device can detect the signal strength of the erase signal and/or the contact area between the cover and the digitizer screen and vary one or more of the width, area, or opacity of the erase function. The computing device can further, based upon the strength of the signal and/or the contact area between the cover and the digitizer screen, determine the tilt and/or the rotation of the stylus.
