Abstract

Techniques for providing a unified computational platform for implementing virtual reality systems. In an aspect, a virtual reality (VR) client includes input and output modules for generating a VR user experience. The client may also incorporate an assistant interface that couples the input and output modules to an assistant server using a semantic information interchange language (SIIL). The assistant server may include a command inference block for converting user-input SIIL messages to command-input SIIL messages, thereby encoding user VR inputs into a general command set that may be recognized and processed by both VR and non-VR modules. Further aspects disclose techniques for seamless integration between virtual environments and joint VR sessions supporting multiple users.

Claims

1. An apparatus comprising:

a command inference block configured to receive from a client a user-input message according to a first protocol specifying an input to a virtual reality system, and to convert the user-input message into a command-input message according to the first protocol; and

at least one plugin module configured to;

transmit a command input specified by the command-input message to an application module;

translate a custom service message received from the application module into a first service message according to the first protocol; and

transmit the first service message to the client.

2. The apparatus of claim 1, the user-input message specifying at least one of a gesture performed by the user and a voice input.

3. The apparatus of claim 1, the command inference block configured to convert the user-input message into the command-input language by being configured to:

receive a context of the user-input message;

retrieve a proposed command from a library based on the received context and the user-input message; and

encapsulate the proposed command in the command-input SIIL message.

4. The apparatus of claim 1, the context comprising at least one of co-presence of other individuals in a joint VR environment when one user generates an input, the user'"'"'s geographic location when generating the input, a time of day when the user input is made, and a direction in which a physical input such as a gesture is made.

5. The apparatus of claim 1, the command inference block configured to convert the user-input message into the command-input language by being configured to:

receive a context of the user-input message;

retrieve a proposed command from a library based on the received context and the user-input message;

if a rejection of the proposed command is received from the user, encapsulate another command suggested by the user in the command-input SIIL message; and

update the library based on the another command suggested by the user.

6. The apparatus of claim 1, the command inference block configured to convert the user-input message into the command-input language by being configured to:

receive a context of the user-input message;

retrieve a proposed command from a library based on the received context and the user-input message;

if the library does not contain a proposed command based on the received context and the user-input message, encapsulate another command suggested by a second user in the command-input SIIL message; and

update the library based on the another command suggested by the second user.

7. The apparatus of claim 1, the command inference block configured to convert the user-input message into the command-input language by being configured to:

receive a plurality of user-input messages from a plurality of users;

receive a context of each user-input message;

retrieve a proposed command from a library based on the plurality of received contexts and the plurality of user-input messages; and

encapsulate the proposed command in the command-input SIIL message.

8. The apparatus of claim 1, the at least one plugin module comprising a first virtual reality (VR) plugin and a second non-virtual reality (non-VR) plugin, the first VR plugin configured to exchange at least one parameter of the user with the second non-VR plugin using a message according to the first protocol, the at least one parameter comprising a credential or authorization associated with a payment instrument owned by the user, an assigned status of the user, and a user profile.

9. The apparatus of claim 1, the at least one plugin module comprising a first virtual reality (VR) plugin and a second virtual reality (VR) plugin, the first VR plugin configured to exchange with the second VR plugin using messages according to the first protocol a virtual environment parameter comprising at least one of a virtual environment coordinate system, relative position of a user in the virtual environment coordinate system, and visual data associated with the virtual environment.

10. The apparatus of claim 9, the first VR plugin configured to exchange data with the second VR plugin using a network communications channel.

11. The apparatus of claim 1, the first service message comprising an instruction to the client to change an output signal generated by a virtual reality output module.

12. The apparatus of claim 1, further comprising a server computer for implementing the command inference block and the at least one plugin module, the server computer configured to communicate with the client using a network connection.

13. The apparatus of claim 1, the command inference block further configured to receive a second user-input message according to the first protocol, and to convert the combination of the user-input message and the second user-input message into a single command-input message according to the first protocol.

14. A method for converting a user-input digital message to a command-input digital message for a virtual reality system, the method comprising:

receiving at least one user-input message according to a first protocol;

receiving a context for each of the at least one user-input message;

retrieving a proposed command, if available, from a digital library mapping user input and context to command inputs;

if a user rejection of the proposed command is not received, encapsulating the proposed command in at least one command-input message according to the first protocol; and

transmitting the command-input message to an application module.

15. The method of claim 14, further comprising:

if a user rejection of the proposed command is received, encapsulating an alternative command specified by a user in the at least one command-input message according to the first protocol; and

updating the digital library to map the user input and context to the alternative command specified by the user.

16. The method of claim 14, further comprising:

if the proposed command is not available from the digital library mapping user input and context to command inputs, receiving an alternative command specified by an alternative user; and

encapsulating the alternative command in the at least one command-input message according to the first protocol.

17. The method of claim 16, the receiving at least one user-input message according to a first protocol comprising receiving at least one user-input message from each of a plurality of users, the retrieving the proposed command comprising retrieving a single proposed command for the plurality of user-input messages from the plurality of users.
