Head mounted display and method for controlling the same

摘要

A head mounted display (HMD) configured to provide a surrounding image is disclosed. The HMD includes a display unit configured to display a section of the surrounding image corresponding to a front direction of the HMD, a first sensor group including at least one sensor configured to sense motion of the HMD, a second sensor group including at least one sensor provided to the HMD to capture a circumjacent image, and a processor configured to control the display unit, the first sensor group and the second sensor group to acquire first sensing information from the first sensor group and second sensing information from the second sensor group, wherein the processor detects a state of the HMD using at least one of the first sensing information and the second sensing information, the state of the HMD including a static state in which an absolute position of the HMD does not change and a moving state in which the absolute position changes, detects, when the state of the HMD is detected as the static state, a direction in which a front of the HMD faces based on the first sensing information or on the first sensing information and the second sensing information, detects, when the state of the HMD is detected as the moving state, the direction in which the front of the HMD faces based on the second sensing information or based on the second sensing information and the corrected first sensing information, and displays an image of a section of the surrounding image corresponding to the detected direction.

1. A head mounted display (HMD) configured to provide a surrounding image, the HMD comprising:
a display unit configured to display a section of the surrounding image corresponding to a front direction of the HMD; a first sensor group comprising at least one sensor configured to sense a motion of the HMD; a second sensor group comprising at least one sensor providing the HMD to capture a circumjacent image; and a processor configured to control the display unit, the first sensor group and the second sensor group to acquire first sensing information from the first sensor group and second sensing information from the second sensor group, wherein the processor is further configured to: detect a state of the HMD using at least one of the first sensing information and the second sensing information, the state of the HMD comprising a static state in which an absolute position of the HMD does not change and a moving state in which the absolute position changes; detect, when the state of the HMD is detected as the static state, a direction in which a front of the HMD faces based on the first sensing information or based on the first sensing information and the second sensing information; detect, when the state of the HMD is detected as the moving state, the direction in which the front of the HMD faces based on the second sensing information or based on the second sensing information and corrected first sensing information; and display an image of a section of the surrounding image corresponding to the detected direction, wherein, in detecting the direction in which the front of the HMD faces based on the second sensing information and the corrected first sensing information, the processor is further configured to: correct the acquired first sensing information; and detect the direction in which the front of the HMD faces using the corrected first sensing information and the second sensing information.
