DISPLAY ZOOM CONTROLLED BY PROXIMITY DETECTION

摘要

Various embodiments provide a user device comprising a touch screen display having a touch screen input; a proximity detector arrangement comprising a plurality of sensors for detecting a location of an input device; and a control unit comprising a processor. The control unit is configured to receive data from the proximity detector to determine the location of the input device, including a value related to the distance of the input device to the display; and control the display to perform a zoom function to enlarge or reduce the size of content on a portion of the display based on the value related to the distance of the input device to the display. The proximity detector arrangement and control unit are configured to detect the location of the input device within a detection volume and to provide a gradual variation in enlargement or reduction of the size of content as the distance of the input device to the display varies. Providing a gradual variation in zoom allows for a more precise and enjoyable user experience.

主权项

1. A user device comprising:
a touch screen display having a touch screen input; a proximity detector arrangement comprising a plurality of sensors for detecting a location of an input device by: detecting a capacitance change due to a change in the minimum distance between the input device and the touch screen display; and producing a voltage change based on the detected capacitance change, the voltage change being linearly related to the minimum distance; a control unit comprising a processor, the control unit being configured to: receive data from the proximity detector to determine the location of the input device, including a value related to the minimum distance of the input device to the display, the value comprising the voltage change; and control the display to perform a zoom function to enlarge or reduce the size of content on a portion of the display based on the value related to the distance from the input device to the display so that the size of content on the display is enlarged from an initial size as the input device moves closer to the display and maintained as the enlarged size as the input device subsequently moves further from the display, the control unit being further configured to resize the content to the initial size in response to a further input on the user device; wherein the proximity detector arrangement and control unit are configured to detect the change in the minimum distance between the input device and the display within a detection volume and to provide a gradual variation in enlargement or reduction of the size of content as the minimum distance from the input device to the display varies.
