A method comprising: utilizing touch sensors of a touch-sensitive display of an electronic device, performing touch detection; when a touch is detected, continuing performing touch detection; when no touch is detected: performing three-dimensional gesture detection to detect gestures spaced from the electronic device utilizing transmitters and receivers, wherein the transmitters and receivers are separate from the touch sensors and wherein the transmitters extend near opposing sides of the touch-sensitive display and the receivers extend near opposing sides of the touch-sensitive display such that a first one of the transmitters extends near and along a length of a first side of the touch-sensitive display, a second one of the transmitters extends near and along a length of a second side of the touch-sensitive display, a first one of the receivers extends near and along a length of a third side of the touch-sensitive display and a second one of the receivers extends near and along a length of a fourth side of the touch-sensitive display, wherein the touch-sensitive display includes a display area in which information is displayable and a non-display area in which information is not displayable, wherein the touch sensors extend across a display area of the touch-sensitive display and wherein the touch sensors perform touch detection to detect touches on the display area and wherein the transmitters and receivers are disposed in the non-display area of the touch-sensitive display; and discontinuing performing three-dimensional gesture detection in response to detecting a touch. utilizing touch sensors of a touch-sensitive display of an electronic device, performing touch detection; when a touch is detected, continuing performing touch detection; when no touch is detected: performing three-dimensional gesture detection to detect gestures spaced from the electronic device utilizing transmitters and receivers, wherein the transmitters and receivers are separate from the touch sensors and wherein the transmitters extend near opposing sides of the touch-sensitive display and the receivers extend near opposing sides of the touch-sensitive display such that a first one of the transmitters extends near and along a length of a first side of the touch-sensitive display, a second one of the transmitters extends near and along a length of a second side of the touch-sensitive display, a first one of the receivers extends near and along a length of a third side of the touch-sensitive display and a second one of the receivers extends near and along a length of a fourth side of the touch-sensitive display, wherein the touch-sensitive display includes a display area in which information is displayable and a non-display area in which information is not displayable, wherein the touch sensors extend across a display area of the touch-sensitive display and wherein the touch sensors perform touch detection to detect touches on the display area and wherein the transmitters and receivers are disposed in the non-display area of the touch-sensitive display; and discontinuing performing three-dimensional gesture detection in response to detecting a touch. performing three-dimensional gesture detection to detect gestures spaced from the electronic device utilizing transmitters and receivers, wherein the transmitters and receivers are separate from the touch sensors and wherein the transmitters extend near opposing sides of the touch-sensitive display and the receivers extend near opposing sides of the touch-sensitive display such that a first one of the transmitters extends near and along a length of a first side of the touch-sensitive display, a second one of the transmitters extends near and along a length of a second side of the touch-sensitive display, a first one of the receivers extends near and along a length of a third side of the touch-sensitive display and a second one of the receivers extends near and along a length of a fourth side of the touch-sensitive display, wherein the touch-sensitive display includes a display area in which information is displayable and a non-display area in which information is not displayable, wherein the touch sensors extend across a display area of the touch-sensitive display and wherein the touch sensors perform touch detection to detect touches on the display area and wherein the transmitters and receivers are disposed in the non-display area of the touch-sensitive display; and discontinuing performing three-dimensional gesture detection in response to detecting a touch.
