Zusammenfassung:The invention provides an object detection method and device using an electronic device. The object detection method includes, in turn, enabling a first light source, a second light source and a third light source to transmit a first light wave signal, a second light wave signal and a third light wave signal; in turn, receiving the first light wave signal, the second light wave signal and the third light wave signal reflected by an object to determine strengths of the first light wave signal, the second light wave signal and the third light wave signal, respectively; and determining a first displacement of the object along a first direction according to strength variances of the first light wave signal and the second light wave signal, and determining a second displacement of the object along a second direction according to strength variances of the first light wave signal and the third light wave signal, wherein the first direction is substantially perpendicular to the second direction. The invention can achieve non-contact control through postures.
