Virtual reality system having adaptive controlling function and controlling method thereof

Abstract

A virtual reality system having adaptive controlling function and a controlling method thereof. The controlling method of a virtual reality system includes the following steps: A sensing signal is obtained by a head-mounted display device. A procedure of transmitting a virtual reality content to the head-mounted display device is adaptively controlled by a host according to the sensing signal.

What is claimed is: 
     
         1 . A controlling method of a virtual reality system, comprising:
 obtaining a sensing signal by a head-mounted display device; and   adaptively controlling a procedure of transmitting a virtual reality content to the head-mounted display device by a host or a portable device according to the sensing signal;   wherein when the sensing signal indicates the user is behind a beat, a play speed of the virtual reality content is reduced; and   when the sensing signal indicates a blood pressure of the user goes up, a soft music is transmitted.   
     
     
         2 . The controlling method of the virtual reality system according to  claim 1 , wherein in the step of adaptively controlling the procedure of transmitting the virtual reality content, a compression ratio, a resolution, a vector complexity, a frame rate, a brightness or a saturation of the virtual reality content is controlled. 
     
     
         3 . The controlling method of the virtual reality system according to  claim 1 , in the step of adaptively controlling the procedure of transmitting the virtual reality content, the procedure of transmitting of the virtual reality content is stopped. 
     
     
         4 . The controlling method of the virtual reality system according to  claim 1 , wherein the sensing signal is a rotating signal, a movement signal, or a vibration signal of the head-mounted display device. 
     
     
         5 . The controlling method of the virtual reality system according to  claim 1 , wherein the sensing signal is a physiological signal of a user. 
     
     
         6 . A virtual reality system, comprising:
 a head-mounted display device for obtaining a sensing signal; and   a host for adaptively controlling a procedure of transmitting a virtual reality content to the head-mounted display device according to the sensing signal;   wherein when the sensing signal indicates the user is behind a beat, a play speed of the virtual reality content is reduced; and   when the sensing signal indicates a blood pressure of the user goes up, a soft music is transmitted.   
     
     
         7 . The virtual reality system according to  claim 6 , wherein the host controls a compression ratio, a resolution, a vector complexity, a frame rate, a brightness or a saturation of the virtual reality content according to the sensing signal. 
     
     
         8 . The virtual reality system according to  claim 6 , wherein the host stops the procedure of transmitting of the virtual reality content according to the sensing signal. 
     
     
         9 . The virtual reality system according to  claim 6 , wherein the sensing signal is a rotating signal, a movement signal, or a vibration signal of the head-mounted display device. 
     
     
         10 . The virtual reality system according to  claim 6 , wherein the sensing signal is a physiological signal of a user. 
     
     
         11 . A head-mounted display device, comprising:
 a sensing unit for obtaining a sensing signal; and   a transmitting unit for transmitting the sensing signal to a host, such that the host adaptively controls a procedure of transmitting a virtual reality content to the head-mounted display device according to the sensing signal;   wherein when the sensing signal indicates the user is behind a beat, a play speed of the virtual reality content is reduced; and   when the sensing signal indicates a blood pressure of the user goes up, a soft music is transmitted.   
     
     
         12 . The head-mounted display device according to  claim 11 , wherein the sensing signal is a rotating signal, a movement signal, or a vibration signal of the head-mounted display device.
