Abstract

A wearable control device for connecting with a head-mounted audio-visual device, includes: a housing including a top housing portion and a bottom housing portion arranged in parallel, wherein a gap is formed between two opposite surfaces of the top housing portion and the bottom housing portion, and tail portions of the top housing portion and the bottom housing portion are connected through a transition portion; at least one physical remote control unit disposed on a top surface of the top housing portion; and a processor disposed inside the housing and electrically connected with the physical remote control unit.

First claim

What is claimed is:

1 . A wearable control device for connecting with a head-mounted audio-visual device, the wearable control device comprising:
a housing; at least one physical remote control unit disposed on the housing; a processor disposed inside the housing and electrically connected with the physical remote control unit; wherein the processor is configured to: generate audio-visual information output by the head-mounted audio-visual device, the audio-visual information including at least one of virtual reality (VR) audio-visual information, augmented reality (AR) audio-visual information, or mixed reality (MR) audio-visual information; generate a control signal of the audio-visual information according to a user operation received by the physical remote control unit; and control output of the audio-visual information according to the control signal.

2 . The wearable control device according to claim 1 , wherein the housing comprises a top housing portion and a bottom housing portion arranged in parallel, tail portions of the top housing portion and the bottom housing portion are connected through a transition portion;
wherein the physical remote control unit is disposed on a top surface of the top housing portion.

3 . The wearable control device according to claim 1 , wherein a gap is formed between opposite surfaces of the top housing portion and the bottom housing portion.

4 . The wearable control device according to claim 2 , wherein the physical remote control unit comprises at least one of a physical key, a virtual key, a roller, a rocker and a track ball.

5 . The wearable control device according to claim 2 , wherein the physical remote control unit comprises a first pressing portion and a second pressing portion arranged in parallel on an edge area of the top surface of the top housing portion; and
wherein the edge region is a localized region of the top surface away from the transition portion.

6 . The wearable control device according to claim 5 , wherein the processor is configured to:
generate at least one of a confirmation signal, a drag control signal, or a multiple-choice control signal matched with the audio-visual information when the user operation is received by the first pressing portion; and generate an auxiliary menu control signal matched with the audio-visual information when the user operation is received by the second pressing portion.

7 . The wearable control device according to claim 5 , wherein the physical remote control unit further comprises:
a first key disposed between the first pressing portion and the second pressing portion.

8 . The wearable control device according to claim 7 , wherein the processor is configured to:
receive a voice signal when the user operation is received by the first key, and generate a voice control signal according to the voice signal, or convert the voice signal into text input.

9 . The wearable control device according to claim 5 , wherein the physical remote control unit further comprises:
a roller disposed between the first pressing portion and the second pressing portion.

10 . The wearable control device according to claim 9 , wherein the processor is configured to:
generate a numerical value adjustment instruction when the user operation is received by the roller; wherein the numerical value adjustment instruction comprises at least one of: a volume adjustment instruction, a brightness adjustment instruction, a visual field size adjustment instruction, a scenario size adjustment instruction, a visual angle rotation instruction, a visual angle distance adjustment instruction, or an Internet of things device adjustment instruction.

11 . The wearable control device according to claim 5 , wherein the physical remote control unit further comprises a second key disposed on a side surface of the bottom housing portion.

12 . The wearable control device according to claim 11 , wherein the processor is configured to generate at least one control signal of a return signal, a previous page signal, or a screen capture signal when the user operation is received by the second key.

13 . The wearable control device according to claim 12 , wherein the processor is configured to generate at least one control signal of a turn-on signal, a turn-off signal, a restart signal, or a power-off signal when the user operation is received by the second key.

14 . The wearable control device according to claim 2 , wherein the transition portion is provided with a connecting wire for connecting with the head-mounted audio-visual device.

15 . The wearable control device according to claim 2 , wherein a length of the top housing portion is shorter than a length of the bottom housing portion.

16 . A wearable control device for connecting with a head-mounted audio-visual device, the wearable control device comprising:
a housing including a top housing portion and a bottom housing portion arranged in parallel, wherein a gap is formed between two opposite surfaces of the top housing portion and the bottom housing portion, and tail portions of the top housing portion and the bottom housing portion are connected through a transition portion; at least one physical remote control unit disposed on a top surface of the top housing portion; and a processor disposed inside the housing and electrically connected with the physical remote control unit.

17 . The wearable control device according to claim 16 , wherein the physical remote control unit comprises at least one of a physical key, a virtual key, a roller, a rocker, or a track ball.

18 . The wearable control device according to claim 17 , wherein the physical remote control unit comprises:
a first pressing portion and a second pressing portion arranged in parallel on an edge region on the top surface of the top housing portion; wherein the edge region is a localized region of the top surface away from the transition portion.

19 . The wearable control device according to claim 16 , wherein the processor is configured to:
generate audio-visual information output by the head-mounted audio-visual device, wherein the audio-visual information includes at least one of virtual reality (VR) audio-visual information, augmented reality (AR) audio-visual information, or mixed reality (MR) audio-visual information; generate a control signal of the audio-visual information according to a user operation received by the physical remote control unit; and control output of the audio-visual information according to the control signal.

20 . A virtual/augmented reality system, comprising:
a head-mounted audio-visual device; and a wearable control device connected with the head-mounted audio-visual device; wherein the wearable control device is the wearable control device according to claim 16 .
