A user interface for receiving input commands in a mobile terminal includes a display device (D) for presenting visual information. Arrays of light sources (131, 132) and arrays of light detectors (141, 142) are arranged along respective first and second sides of the display device (D). Each array of light sources (131, 132) is configured to transmit light pulses (ΛemX, ΛemY) over the display device (D), and each array of light detectors (141, 142) is configured to receive a part (Λin, ΛinY) of the energy in the transmitted light pulses (ΛemX, ΛemY). A processing unit (110) controls the light sources (131, 132) such that a respective light pulse (ΛemX, ΛemY) is repeatedly transmitted from each source (LX1, . . . , LXn; LY1, . . . , LYm) in the arrays according to a predefined sequence. However, prior to transmitting the light pulse (ΛemX, ΛsrriY). an initial measurement value (V1) registered by at least one detector (Dph) in the at least one array of light detectors (141, 142) is recorded. Thus, the initial measurement value (V1) represents an ambience light intensity. Based on the initial measurement value (V1) and a secondary measurement value (V2) registered by at least one light detector (Dph) during emission of light from the light source (Dem), the processing unit (110) determines whether or not a light-obstructive object is present on the display device (D) between a given light source (Dem) in the arrays of light sources (131, 132) and at least one light detector (Dph) in the at least one array of light detectors (141, 142).
