Description

Technical Field

[0001] This utility model belongs to the field of VR controller technology, specifically relating to an obstacle avoidance controller. Background Technology

[0002] Currently, VR headsets only allow users to see their surroundings in VST (Video See-Through) mode. In other modes, users can only see the content played by the VR headset. Therefore, when a user is in a fixed space in a room and not in VST mode, the human eye cannot see or perceive the distance between themselves and obstacles in the game scene. In sports games such as ping-pong, the user may move with the changing environment, potentially hitting walls or other obstacles while swinging their hands. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an obstacle avoidance handle that can effectively assist in setting the safe use area of ​​the handle, provide corresponding alarm prompts, and prevent people from being injured by hitting obstacles.

[0007] Furthermore, the controller also includes a clock chip.

[0008] Furthermore, the detection device is positioned in front of the handle body on the side furthest from the body.

[0009] Furthermore, the detection device is located at the edge of the top of the handle body.

[0010] Furthermore, the main body of the handle is provided with a communication unit for communicating with the VR host. The communication unit is electrically connected to the controller for transmitting warning signals or alarm signals issued by the controller.

[0011] Furthermore, an alarm unit is provided on the handle body, and the alarm unit is electrically connected to the controller to receive warning signals or alarm signals issued by the controller.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the textual part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0021] like Figure 1 and Figure 2 As shown, an obstacle avoidance handle includes a handle body 1 and a controller MCU. The controller can be a microcontroller. The handle body 1 is provided with a detection device 2 for detecting the distance between the handle body 1 and an obstacle 3 (such as a wall or furniture). The detection device 2 is electrically connected to the controller. When the distance between the handle body 1 and the obstacle 3 is lower than the safe distance, the controller issues a warning signal or an alarm signal.

[0022] The detection device 2 includes one of an ultrasonic sensor, an infrared sensor, or a ranging camera. The controller also includes a clock chip (RTC). When using an ultrasonic sensor or an infrared sensor for ranging, the clock chip is used for calculation. Taking an ultrasonic sensor as an example, the speed of sound in air is approximately 340 meters per second. After the ultrasonic wave is set to be emitted, the controller sets the clock chip to start timing T. The distance s between the ultrasonic wave and the obstacle 3 is calculated using the formula: s = 340 * T / 2.

[0023] like Figure 1 As shown, the detection device 2 is positioned in front of the handle body 1 on the side furthest from the body. That is, when the handle is a left handle, the detection device 2 is located on the left front side of the handle body 1, and when the handle is a right handle, the detection device 2 is located on the right front side of the handle body 1. Since the detection direction of the detection device 2 is fan-shaped, the position of the detection device 2 can detect the shortest distance between it and the obstacle 3.

[0024] To prevent the opening for transmitting detection signals from the detection device 2 from being blocked by the user's hand, the detection device 2 is located at the edge of the top of the handle body 1.

[0025] like Figure 2 As shown, the safety distance is set to two values. When the distance *s* between the handle and obstacle 3 is lower than the first safety distance *S1*, it is considered that the handle is too close to obstacle 3, and the controller issues a warning signal. When the distance *s* between the handle and obstacle 3 is lower than the second safety distance *S2*, it is considered that the handle or hand is about to touch obstacle 3, and the controller issues an alarm signal, where *S1* > *S2*. In the figure, handle position 1 is the critical position of the first safety distance *S1*, and handle position 2 is the critical position of the second safety distance *S2*.

[0026] The specific value of the second safety distance S2 needs to be investigated to ensure it is suitable for the general population. S2 should be greater than the longest arm length of the general population to ensure that no one using the product will touch the wall. Alternatively, the safety distance can be set manually by the VR host, which will then transmit the S1 or S2 setting to the controller.

[0027] Warning and alarm prompts can be indicated in different locations. In one embodiment of this application, the main body 1 of the controller is provided with a communication unit for communication with a VR host (generally a head-mounted display device). The communication unit is electrically connected to the controller and is used to transmit warning or alarm signals issued by the controller. The warning or alarm signals are sent to the VR host through the communication unit, and the VR host reminds the user through voice or text. Depending on whether the communication between the controller and the VR host is wired or wireless, the communication unit can be a corresponding data cable interface, USB interface, or wireless transmission chip, etc.

[0028] Another embodiment of this application involves an alarm unit mounted on the handle body 1. This alarm unit is electrically connected to the controller and is used to receive warning or alarm signals from the controller, thus alerting the user via the handle. The alarm unit can be a buzzer, alerting the user with a specific sound, or a vibration device, alerting the user with vibration. The vibration device can be a miniature vibration motor. It is important to note that warning and alarm prompts need to be distinguished, such as by the volume of the sound, the magnitude of the vibration, and its duration.

[0029] Preferably, in this application, the grip portion of the handle body 1 is equipped with a grip detection device for detecting whether a user is gripping the handle. The grip detection device is electrically connected to the controller. Specifically, the grip detection device is a touch chip or a pressure sensor. When the grip detection device detects that a hand is gripping the handle, it sends a signal to the controller, which then controls the detection device 2 to start detection, thereby reducing power consumption.

[0030] To further reduce power consumption, the detection device 2 performs scanning detection at a certain frequency. When the handle is far from the obstacle 3, the scanning frequency can be slower; when the handle is close to the obstacle 3, the scanning frequency should be increased, the scanning interval time shortened, the alarm response accelerated, and the possibility of collision with the obstacle 3 reduced.

[0031] Therefore, when the distance between the handle and obstacle 3 is lower than the first safe distance but higher than the second safe distance, i.e., S2 < s < S1, the detection device 2 scans once every t1 time interval. When the distance between the handle and obstacle 3 is lower than the second safe distance, i.e., s < S2, the detection device 2 scans once every t2 time interval. Where t2 < t1.

[0032] The obstacle avoidance handle of this utility model has a detection device on the handle body that can detect the distance between the handle body and the obstacle. When the distance is lower than the set safe distance, the controller issues a warning signal or alarm signal to remind the user, thereby effectively assisting in setting the safe use area of ​​the handle and preventing the hand from hitting the obstacle and causing injury.
