Abstract
An apparatus and a method for controlling an electronic device using head tracking technology are provided. The method includes detecting face motion from an image captured through a camera of the electronic device and executing a control service corresponding to the detected face motion information.
Claims20
A method in an electronic device, the method comprising:
- executing an application;
- extracting control information corresponding to a type of the executed application from a non-transitory memory of the electronic device;
- capturing at least one image from at least one camera of the electronic device, the at least one image including a partial image of at least one target object;
- estimating an entire image by comparing the partial image of the at least one target object with another image of the at least one target object stored in the non-transitory memory;
- determining one of the extracted control information based on the estimated entire image of the at least one target object;
- and
- controlling the application corresponding to the determined control information;
- determining whether the at least one target object moves out of a reference range, the determination based on a face motion angle of the at least one target object,
- wherein the controlling of the application comprises:
- pausing video play when the at least one target object moves out of a reference range, or
- maintaining video play when the at least one target object does not move out of a reference range,
- wherein, when the at least one target object moves out of the reference range, the extracted control information is a pause control information, and
- wherein, when the at least one target object does not move out of the reference range, the extracted control information is a control information for maintaining a screen state.

An electronic device comprising:
- at least one camera;
- a display;
- a non-transitory memory;
- and
- at least one processor,
- wherein the at least one processor is configured to:
- execute an application,
- extract control information corresponding to a type of the executed application from the memory,
- capture at least one image from the at least one camera, the at least one image including a partial image of at least one target object,
- estimate an entire image by comparing the partial image of the at least one target object with another image of the at least one target object stored in the non-transitory memory,
- determine one of the extracted control information based on the estimated entire image of the at least one target object, and
- control the application corresponding to the determined control information;
- determine whether the at least one target object moves out of a reference range, the determination based on a face motion angle of the at least one target object,
- pause video play when the at least one target object moves out of a reference range, or maintain video play when the at least one target object does not move out of a reference range,
- wherein, when the at least one target object moves out of the reference range, the extracted control information is a pause control information, and
- wherein, when the at least one target object does not move out of the reference range, the extracted control information is a control information for maintaining a screen state.
