Abstract

Detecting which hand is interacting with a device can enhance the experience of a user. As illustrated in Figure 1, the button area containing the touch interface of a device can be placed in a region of the display that the user is better able to reach. In response to detecting handedness, the GUI of the device can be adjusted so that interactive regions of the display are within easy (i.e. without physical readjustment) reach of the user.. As illustrated in the exemplary Figure 1, if the thumb of a left hand is being used, the button area is placed on the left side of the display, and if a right hand is being used, the button area is placed on the right side of the display. Handedness is determined using existing 2D imaging data gathered through capacitive touch screen interaction. No additional sensors, such as on the side of the device, are needed to detect handedness – thus avoiding problematic baseline issues associated with a hand gripping the device at power-up. By detecting handedness through sensors already included in capacitive touchscreens, there is no increase in materials cost.

4. Some Problems Solved

Examples of some of the problems addressed by the invention include:

For large form-factor devices (e.g. phones and tablets), when operated using only one hand, a users thumb can't traverse the entire screen resulting in some areas being out of reach.

Analyzing screen interaction to determine which hand of a user is interacting with the device, allows the user interface to be adapted so that all buttons are within reach of the thumb being used - improving usability..


5. General Description

When using a smartphone or similar device, the opening screen, or lock screen, does not typically benefit significantly from adaptation for handedness. The device displays the lock screen without consideration of handedness and may detect handedness based on interaction with the lock screen when the user unlocks the device. After unlocking the devi...
