Abstract
A head mounted display and a control method thereof are provided. The control method includes the following. An eye-tracking operation is activated to obtain a gazing direction of a user. At least one setting position is set on a display frame, and the at least one setting position serves to set at least one static object. Whether to display or hide the static object is determined according to the setting position and the gazing direction.
Claims12
A control method of a head mounted display, comprising:
- activating an eye-tracking operation to obtain a gazing direction of a user;
- setting at least one setting position in a display frame, wherein the at least one setting position serves to set at least one static object;
- determining to display the at least one static object when the at least one static object is outside the reference field-of-view, and determining to hide the at least one static object when the at least one static object is inside the reference field-of-view.
A head mounted display, comprising:
- an eye-tracking device performing an eye-tracking operation;
- a display device generating a display frame and at least one static object;
- and
- a controller, configured to:
- activate the eye-tracking operation of the eye-tracking device to obtain a gazing direction of a user;
- set at least one setting position on the display frame, wherein the at least one setting position serves to set at least one static object;
- control the display device to display the at least one static object when the at least one static object is outside the reference field-of-view, and to hide the at least one static object when the at least one static object is inside the reference field-of-view,
- wherein the eye-tracking operation is obtained by calculating a gazing direction of the other eye measured by the eye-tracking device, a pupil distance between two eyes, and a spatiotemporal positioning state of the head mounted display.

A calibration method for a head mounted display, comprising:
- measuring a field-of-view of a user, obtaining a current maximum field-of-view of the user through one of a plurality of methods performed by the user, and thereby setting a position of a static object, comprising determining to display the static object when the static object is outside the field-of-view, and determining to hide the static object when the static object is inside the field-of-view;
- and
- playing a plurality of frames with different positions, sizes, shapes, and colors of static objects, wherein after a start, the user is asked to look straight at a central reference point, and the user is asked to answer whether an existence of the static object is visually perceived.
