Abstract
A head mounted display apparatus and a display method for an eye-tracking cursor are provided. The display method for an eye-tracking cursor includes: projecting a display image, and starting a cursor tracking function; detecting a first staring point of eyes on the display image; setting a first cursor on the first staring point; and detecting a first visual distance between the first staring point and the eyes, and adjusting a dimension of the first cursor according to the first visual distance so that a value of a view angle of the eyes with respect to the first cursor is equal to a preset value.

A display method for an eye-tracking cursor, comprising:
- projecting a display image by a display, and starting a cursor tracking function;
- detecting a first staring point of eyes by an eye-tracking action performed by a controller on the display image;
- setting a first cursor on the first staring point;
- detecting a first visual distance by the controller between the first staring point and the eyes, and adjusting a dimension of the first cursor according to the first visual distance so that a value of a view angle of the eyes with respect to the first cursor is equal to a preset value;
- detecting a second staring point of the eyes, and setting a second cursor on the second staring point;
- detecting a second visual distance between the second staring point and the eyes, wherein the first visual distance and the second visual distance are different;
- and
- adjusting a dimension of the second cursor according to the second visual distance so that a value of a view angle of the eyes with respect to the second cursor is equal to the preset value as the value of a view angle of the eyes with respect to the first cursor.
A head mounted display apparatus, comprising:
- a display, configured to project a display image;
- and
- a controller, coupled with the display, and configured to:
- start a cursor tracking function;
- detect a first staring point of eyes on the display image;
- enable the display to set a first cursor on the first staring point;
- detect a first visual distance between the first staring point and the eyes, enable the display to adjust a dimension of the first cursor according to the first visual distance so that a value of a view angle of the eyes with respect to the first cursor is equal to a preset value;
- detect a second staring point of the eyes, and enable the display to set a second cursor on the second staring point;
- detect a second visual distance between the second staring point and the eyes, wherein the first visual distance and the second visual distance are different;
- and
- adjust a dimension of the second cursor according to the second visual distance so that a value of a view angle of the eyes with respect to the second cursor are same value as the preset value as the value of a view angle of the eyes with respect to the first cursor.
