Abstract
A method of estimating a position of an image display device, the method including determining position information of a neck of a user based on position information of an image display device worn by the user, filtering the position information of the neck, and estimating a position of the image display device based on the filtered position information of the neck.
Claims26
A method of estimating a position of an image display device, the method comprising:
- determining position information of a neck of a user based on position information of an image display device worn by the user;
- filtering the position information of the neck;
- and
- estimating a position of the image display device based on the filtered position information of the neck.
An image display device, comprising:
- a processor configured to
- determine position information of a neck of a user based on position information of the image display device worn by the user,
- filter the position information of the neck, and
- estimate a position of the image display device based on the filtered position information of the neck.
An image display device, comprising:
- a processor configured to
- determine position information of a neck of a user based on position information of the image display device worn by the user,
- filter position change information in the position information of the neck by setting a cut-off frequency of a low-pass filter to be higher than a threshold, in response to the position change information being greater than a reference value,
- filter the position change information by setting the cut-off frequency of the low-pass filter to be lower than the threshold, in response to the position change information being lesser than or equal to the reference value, and
- estimate a position of the image display device based on the filtered position information of the neck;
- and
- a display configured to display an image rendered based on the estimated position of the image display device.
A method of estimating a position of an image display device, the method comprising:
- determining position information of a part of a body of a user based on position information of an image display device worn by the user;
- filtering the position information of the part of the body using an adaptive low pass filter;
- and
- estimating a position of the image display device based on applying relational position information between the image display device and the part of the body to the filtered position information of the part of the body.
