Abstract
Provided are an electronic device and an operation method thereof according to embodiments. The electronic device according to an embodiment includes an optical module configured to radiate light to an object and to detect a distance to the object from the electronic device by using light reflected from the object. The electronic device further includes a processor configured to determine touch information and/or gesture information of the object based on information about the detected distance to the object.
Claims18
An electronic device comprising:
- an optical module configured to radiate light to an object and detect a distance between the object and the electronic device by using light reflected from the object, the optical module comprising one or more light sources, a light path change element configured to change a path of light from the one or more light sources and to deliver the light to the object, a distance detection sensor configured to receive light reflected from the object and to detect the distance based on the reflected light, and a rotation element configured to rotate the light path change element;
- and
- a processor configured to:
- control the optical module to detect the distance, and
- determine touch information and/or gesture information of the object based on the detected distance,
- receive, via a communication interface, a signal indicating that an application is executed in an external device, from the external device, and
- adjust a control factor for controlling the optical module based on a type of the application being executed in the external device, the control factor comprising at least one of a strength of the one or more light sources, and a rotation speed of the rotation element, the application being a computer program which is executed in the external device connected through the communication interface, to perform a function, a task, or an activity for helping a user's motion,
- wherein the processor is further configured to adjust a strength of the one or more light sources or the rotation speed of the rotation element differently according to the type of the application.
