1. Control operation of the plurality of proximity sensing points by adjusting one or more of resolution and sensitivity of gesture detection in the interaction area, wherein a number of operational proximity sensing points increases from a first number to a second number after motion is detected in the interaction area based on an application being executed on the device; a processor; and a memory arranged to store executable instructions, which when executed by the processor, cause the processor to: control operation of the plurality of proximity sensing points by adjusting one or more of resolution and sensitivity of gesture detection in the interaction area based on an application being executed on the device, wherein a number of operational proximity sensing points increases from a first number to a second number after motion is detected in the interaction area; create a sequence of proximity sensor images from data received from the second number of operational proximity sensing points; and analyze the sequence of proximity sensor images to identify a user gesture in the interaction area.
