Abstract

An electronic system includes a hand-held controller and a computing application. The hand-held controller includes a proximity sensing circuit and a physical information sensing circuit. The proximity sensing circuit includes proximity sensors. The proximity sensors are configured to sense instant proximity values. The physical information sensing circuit is configured to sense a physical parameter. The computing application is executed by a processor. The computing application is configured to retrieve the instant proximity values and the physical parameter, to calculate maximum proximity values or minimum proximity values according to the instant proximity values and the physical parameter. The maximum proximity values or the minimum proximity values are utilized to update threshold proximity values of the proximity sensors in determining near status or far status.

BACKGROUND 

Field of Invention

Present disclosure relates to a system and a method for proximity detection. More particularly, the present disclosure relates to a system and a method for calibrating or updating a threshold value of proximity detection.

Description of Related Art

Proximity detection is a technology to detect a distance from a proximity sensor to a target object. The proximity sensor may generate a proximity value which reflects the distance. When the proximity value exceeds a threshold, the proximity sensor detects that the target object is near. On the other hand, when the proximity value is below a threshold, the proximity sensor detects that the target object is far. Proximity detection is useful in various applications. For example, the proximity sensor can be disposed on a mobile phone to detect whether the user is adjacent to the phone.

SUMMARY 

The disclosure provides an electronic system, which includes a hand-held controller and a computing application. The hand-held controller includes a proximity sensing circuit and a physical information sensing circuit. The proximity sensing circuit includes proximity sensors. The proximity sensors are configured to sense instant proximity values. The physical information sensing circuit is configured to sense a physical parameter. The computing application is executed by a processor. The computing application is configured to retrieve the instant proximity values and the physical parameter, to calculate maximum proximity values or minimum proximity values according to the instant proximity values and the physical parameter. The maximum proximity values or the minimum proximity values are utilized to update threshold proximity values of the proximity sensors in determining near status or far status.

Another aspect of present disclosure is to provide a proximity sensing method, which include following steps. Instant proximity values are sensed by proximity sensors disposed on a hand-held controller. A physical parameter is sensed by a physical information sensing circuit disposed on the hand-held controller. Maximum proximity values or minimum proximity values are calculated according to the instant proximity values and the physical parameter. The maximum proximity values or the minimum proximity values are utilized to update threshold proximity values of the proximity sensors in determining near status or far status.

It is to be understood that both the foregoing general description and the following detailed description are by examples, and are intended to provide further explanation of the disclosure as claimed.
