HTC has filed a patent for a head-mounted display device with two sensors. The sensors are placed on different areas of the main body, each with a central point on a horizontal axis. The connection lines between the central points and sensors form different angles with the horizontal axis.

Head-mounted display device with two sensors at different angles
A recently filed patent (Publication Number: US20230319425A1) describes a head-mounted display device with multiple sensors. The device includes a main body and two sensors, each located on a different area of the main body. These areas have central points that are positioned on a horizontal axis. The connection lines between the central points and the sensors form angles with the horizontal axis, and these angles are different for each sensor.
The patent claims that the absolute value of the difference between the angles of the two sensors must be greater than a preset threshold. This requirement ensures that the sensors are positioned in a way that allows for accurate and reliable data capture.
The first setting area of the device is divided into multiple partitions based on the angle with the horizontal axis, and the second setting area is also divided into corresponding partitions. The sensors are placed on selected partitions that do not correspond to each other. Additionally, each partition in both areas has the same central angle, ensuring consistency in the device's design.
The first setting area corresponds to the position of the user's first eye, while the second setting area corresponds to the position of the user's second eye. The first sensor captures image information of the first eye, and the second sensor captures image information of the second eye.
To enhance the reliability of the captured image information, the device includes an eye tracker that calculates weights based on the reliability of the image information from each sensor. These weights are then used to generate binocular image information.
The reliability of the image information is determined by factors such as occlusion of the eye image, deformation of the pupil image, influence of fog or reflection, and influence of external light. The eye tracker calculates the reliability at multiple time points to obtain the weights.
Furthermore, the patent claims that the first weight is complementary to the second weight, suggesting that the device balances the importance of the image information from each eye.
Overall, this patent describes a head-mounted display device with multiple sensors that are positioned in a specific way to ensure accurate data capture. The device includes an eye tracker to enhance the reliability of the captured image information.
