Abstract

Mobile devices are decreasing in size and increasing in features. Hardware feature on the devices are increasingly competing for real estate. Features such as antennas may drive the position of buttons. Sometimes these hardware features force buttons to be located in non-ideal positions. These non-ideal positions can cause issues with inadvertent button actuation which may cause usability problems with the device. As an example, in one common scenario a lock/power button may need to be located opposite a PTT (push to talk) button, causing the user to unlock or power down a device when pressing the PTT button. Conversely, a user attempting to power down the device may accidentally press the PTT key and initiate a PTT session. This invention provides a method to eliminate issues of accidental actuation by intelligently filtering/deactivating keys when the user is touching/pressing certain keys.

Method of Filtering Button presses on a Mobile Device

Mobile devices are decreasing in size and increasing in features. Hardware feature on the devices are increasingly competing for real estate. Features such as antennas may drive the position of buttons. Sometimes these hardware features force buttons to be located in non-ideal positions. These non-ideal positions can cause issues with inadvertent button actuation which may cause usability problems with the device. As an example, in one common scenario a lock/power button may need to be located opposite a PTT (push to talk) button, causing the user to unlock or power down a device when pressing the PTT button. Conversely, a user attempting to power down the device may accidentally press the PTT key and initiate a PTT session. This invention provides a method to eliminate issues of accidental actuation by intelligently filtering/deactivating keys when the user is touching/pressing certain keys.

Our invention uses sensing technology embedded in the devices keys to understand where the user's fingers are placed and intelligently activate or de-activate keys to avoid accidental key actuation. By using a simple capacitive or pressure sensor embedded in each key the device would be able to de- activate specific keys when a user's finger is located on another key. For example, a capacitive sensor located within a PTT key would sense that a user's finger is on the PTT key and therefore deactivate the power/lock combin...
