Abstract: Sensors capable of detection of user objects within different detection zones can be used to reduce power consumption of a touch screen interface of an electronic device, even while the device is in a suspended or sleep state. At least one object sensor, such as a capacitive sensor, has a detection zone or range exceeding the range of a touch screen sensor, so the touch screen sensor can be placed into a low power state until the object sensor detects a user object in a position approaching the touch screen. The object sensor(s) are positioned around or within the perimeter of the interaction area of the touch screen. The object sensor(s) can have less power consumption than the touch screen sensors, so the electronic device can have extended standby battery life or other more energy efficient operation. Object sensors are also used to detect gestures or user object positioning.
