Abstract
Description
[Technical Field]
[0001] This case relates to a split virtual reality (VR) device with selectable wireless communication power. [Previous Technology]
[0002] Specific Absorption Rating (SAR) is an indicator used to measure the absorption rate of electromagnetic radiation exposed to the human body. To avoid adverse effects of electromagnetic radiation on the human body, relevant government agencies have established legally mandated SAR safety standards to clearly define the maximum safe values permissible in different parts of the human body. Taking virtual reality (VR) devices as an example, VR devices primarily create a virtual 3D space using a computer. They typically include a VR headset with a display to play various 3D simulated scenes and a VR host to transmit and receive radio frequency signals. Since the VR headset and VR host in a VR device are integrated into a single unit, only one power meter is needed; no other power meters are required. [Summary of the Invention]
[0003] This application provides a detachable virtual reality device for a user to wear, with a first position on the user's body. The detachable virtual reality device includes a detachable helmet and a detachable host. The detachable helmet is worn on the user's head, and a second position is provided on the detachable helmet. The detachable host is electrically connected to the detachable helmet, and the detachable host selects a corresponding first power meter or a second power meter based on whether the detachable host is in the first or second position, so as to transmit and receive a radio frequency signal according to the first or second power meter.
[0004] In summary, under a split virtual reality architecture, specific absorption rates require different legally prescribed values. This application proposes a split virtual reality device that can detect the location of the split host within the user's environment under different conditions, and select different power meters based on the host's location. Therefore, the split virtual reality device of this application can adaptively select an appropriate power meter to automatically adjust communication power to comply with SAR specifications, thereby improving product security.
Implementation Method
[0005] The embodiments of this case will be described below with reference to the relevant drawings. Furthermore, some components or structures are omitted in the drawings of the embodiments to clearly show the technical features of this case. In these drawings, the same reference numerals denote the same or similar components or circuits. It must be understood that although the terms "first," "second," etc., can be used herein to describe various components, parts, areas, or functions, these components, parts, areas, and / or functions should not be limited by these terms. These terms are only used to distinguish one component, part, area, or function from another component, part, area, or function.
[0006] Referring to Figure 1, a detachable virtual reality device 20 is provided for a user 10 to wear, and the user 10 has a first position 12 on their body, which is usually located on the user 10's limbs or body. The detachable virtual reality device 20 includes a detachable helmet 22 and a detachable host 24. The detachable helmet 22 is worn on the user 10's head and is a helmet with a display. A second position 26 is provided on the detachable helmet 22, which is close to the user 10's head. The detachable host 24 is electrically connected to the detachable helmet 22. The detachable host 24 performs a detection mechanism to select a corresponding first power meter or a second power meter based on whether the detachable host 24 is located at the first position 12 or the second position 26, and transmits and receives radio frequency signals based on the first power meter or the second power meter.
[0007] In one embodiment, the first power meter includes a preset communication power value at a first position 12. This predicted communication power value is typically the legally prescribed value (maximum power value) corresponding to the first position 12 as specified in SAR regulations. The second power meter includes a preset communication power value at a second position 26. This predicted communication power value is typically the legally prescribed value (maximum power value) corresponding to the second position 26 as specified in SAR regulations. The first and second power meters are stored in a storage device (not shown) within the separate host 24, allowing the separate host 24 to select the corresponding first or second power meter from the storage device based on its location. In one embodiment, the storage device is a non-volatile memory.
[0008] Please refer to Figures 1 and 2. The detachable main unit 24 is worn on the user 10 via a strap 28 and is located at the first position 12. For example, it can be worn on the user 10's arm 14 or waist via the strap 28. In this embodiment, the detachable main unit 24 is installed on the user 10's arm 14, but this is not a limitation. When the detachable main unit 24 is worn on the user 10's arm 14 via the strap 28 and is located at the first position 12, the first position 12 is a position that is relatively far away from the detachable helmet 22. Therefore, the position of the detachable main unit 24 can be determined through the detection mechanism. At this time, it is determined that the detachable main unit 24 is located at the first position 12, so a first power meter suitable for the first position 12 can be selected.
[0009] Please refer to Figures 1 and 3. A support 30, such as a locking seat, is provided at the second position 26 of the split helmet 22, so that the split main unit 24 is mounted on the support 30. When the split main unit 24 is mounted on the split helmet 22 through the support 30 and is located at the second position 26, this second position 26 is a position close to the split helmet 22. Therefore, the position of the split main unit 24 can be determined through the detection mechanism. At this time, it is determined that the split main unit 24 is located at the second position 26, so a second power meter suitable for the second position 26 can be selected.
[0010] Please refer to Figures 1, 2 and 3 at the same time. In the split virtual reality device 20, the split host 24 is further equipped with a processing device 241 to perform a detection mechanism to determine whether the split host 24 itself is located at the first position 12 or the second position 26. The various detection mechanisms are explained below.
[0011] In one embodiment, the split host 24 further includes a Hall sensor 242. There may be one or more Hall sensors 242. In this embodiment, one Hall sensor 242 is used as an example, but the number of Hall sensors 242 can be determined according to actual needs, and this invention is not limited thereto. This Hall sensor 242 is electrically connected to the processing device 241 to detect whether the split host 24 is located at the first position 12 or the second position 26, thereby selecting a suitable first power meter or second power meter.
[0012] In one embodiment, referring to Figures 1, 2, and 3 simultaneously, the split virtual reality device 20 further includes a transmission cable 32. The split helmet 22 is connected to the split host 24 via this transmission cable 32. The transmission cable 32 can be selected from a first transmission cable 321 or a second transmission cable 322. The first transmission cable 321 has a first identification code, and the second transmission cable 322 has a second identification code. When the split host 24 is in the first position 12, the split host 24... The 4-series is connected to the detachable helmet 22 via the first transmission cable 321. When the detachable main unit 24 is in the second position 26, the detachable main unit 24 is connected to the detachable helmet 22 via the second transmission cable 322. Therefore, the processing device 241 can identify whether the detachable main unit 24 is connected to the detachable helmet 22 via the first transmission cable 321 or the second transmission cable 322 based on the first identification code and the second identification code, so as to determine whether the detachable main unit 24 is in the first position 12 or the second position 26 via different transmission cables 32. When the processing device 241 detects the first identification code, it indicates that the separate helmet 22 is connected to the separate host 24 via the longer first transmission cable 321. Therefore, the separate host 24 is located at the first position 12, as shown in Figure 2, to select a suitable first power meter. When the processing device 241 detects the second identification code, it indicates that the separate helmet 22 is connected to the separate host 24 via the shorter second transmission cable 322. Therefore, the separate host 24 is located at the second position 26, as shown in Figure 3, to select a suitable second power meter.
[0013] In one embodiment, the detachable helmet 22 further includes a plurality of image capturing elements 221. The detachable helmet 22 can capture surrounding images through the image capturing elements 221 and transmit them to the processing device 241 in the detachable host 24 via the transmission cable 32, so that the processing device 241 can determine whether the detachable host 24 is located at the first position 12 or the second position 26 based on the images, so as to select a suitable first power meter or second power meter.
[0014] In one embodiment, the detachable helmet 22 further includes a first radio frequency module 222, and the detachable host 24 further includes a second radio frequency module 243, and the second radio frequency module 243 is electrically connected to the processing device 241. The detachable host 24 can further determine whether it is located in a first position or a second position based on the radio frequency strength between the second radio frequency module 243 and the first radio frequency module 222. When the detachable host 24 reads the first radio frequency module 222 of the detachable helmet 22 through the second radio frequency module 243, if the radio frequency signal strength is weaker, it indicates that the distance between the detachable host 24 and the detachable helmet 22 is farther, so the detachable host 24 is located in the first position 12, as shown in FIG2, to select a suitable first power meter; if the radio frequency signal strength is stronger, it indicates that the distance between the detachable host 24 and the detachable helmet 22 is closer, so the detachable host 24 is located in the second position 26, as shown in FIG3, to select a suitable second power meter.
[0015] In one embodiment, the processing device 241 is a central processing unit (CPU), or other general-purpose or special-purpose microprocessor, microcontroller, micro control unit (MCU), digital signal processor (DSP), programmable controller, application-specific integrated circuit (ASIC), or other similar elements or combinations thereof, and this invention is not limited thereto.
[0016] In one embodiment, as shown in FIG4, the detachable main unit 24 can be worn on the user 10 and located at a first position 12 via a clamp 34. This clamp 34 can be a clip or a buckle. For example, the detachable main unit 24 can be worn on the user 10's pocket 16 via the clamp 34. In this embodiment, the detachable main unit 24 is installed on the user 10's upper garment pocket 16, but this is not limited to this. The detachable main unit 24 can be worn on the user 10 at any position via the clamp 34. When the detachable main unit 24 is worn on the user 10's pocket 16 and located at the first position 12 via the clamp 34, the first position 12 is a position farther away from the detachable helmet 22. Therefore, the position of the detachable main unit 24 can be determined through the detection mechanism. At this time, it is determined that the detachable main unit 24 is located at the first position 12, so a first power meter suitable for the first position 12 can be selected.
[0017] In summary, under a split virtual reality architecture, a specific absorption rate (SAR) requires different legally prescribed values. Based on this, this application proposes a split virtual reality device that can detect the location of the split host within the user's context under different conditions, and select different power meters according to the location of the split host. Therefore, the split virtual reality device of this application can adaptively select an appropriate power meter to automatically adjust communication power to comply with SAR specifications, thereby improving product security.
