Wireless augmented reality communication system

Abstract

The system of the present invention is a highly integrated radio communication system with a multimedia co-processor which allows true two-way multimedia (video, audio, data) access as well as real-time biomedical monitoring in a pager-sized portable access unit. The system is integrated in a network structure including one or more general purpose nodes for providing a wireless-to-wired interface. The network architecture allows video, audio and data (including biomedical data) streams to be connected directly to external users and devices. The portable access units may also be mated to various non-personal devices such as cameras or environmental sensors for providing a method for setting up wireless sensor nets from which reported data may be accessed through the portable access unit. The reported data may alternatively be automatically logged at a remote computer for access and viewing through a portable access unit, including the user's own.

Description

RELATED APPLICATIONS [0001] This application is based on provisional patent application Ser. No. 60 / 115,993 filed Jan. 15, 1999.GOVERNMENT LICENSE RIGHTS [0002] The U.S. Government has certain rights in this invention pursuant to NAS7-1407 awarded by NASA.BACKGROUND OF THE INVENTION [0003] 1. Field of the Invention [0004] The invention is a wireless augmented reality system (WARS) that leverages communications and multimedia information processing microelectronics, along with displays, imaging sensors, biosensors, and voice recognition to provide hands-free, tetherless, real-time access and display of network resources, including video, audio and data. [0005] 2. Description of the Prior Art and Related Information [0006] Online instruction manuals are becoming more prevalent in the industrial and everyday environment. These electronic technical manuals (ETM) may be interactive. Just as with printed manuals, ETMs may become very difficult to use and maintain in these environments whe...

AI Technical Summary

Benefits of technology

"The present invention is a personal communications system designed for use in space environments such as the shuttle and station. The system provides high-rate wireless access to data channels for multimedia devices and computer-controlled equipment. It allows for hands-free and unrestricted movement throughout the vehicle or station, providing efficient and effective communication for the astronauts. The system also allows for remote monitoring and control of equipment, as well as in-the-home entertainment and communication applications. The small, wearable portable access unit (PAU) communicates over high-rate link to a centrally-located network access unit (called a general purpose node), which supports multiple-user access for video, audio, and sensor data services. The system is adaptable to various environments and applications, including medical diagnosis and treatment, industrial inspection and maintenance, and commercial mission control."

Problems solved by technology

Just as with printed manuals, ETMs may become very difficult to use and maintain in these environments where elements of an environment, such as dust, chemical or general harshness may be detrimental to the electronics and storage devices used to display and operate the ETM.

Further, it is not always possible for a worker who requires access to an ETM to stop work to consult ETM.

During intra and extra vehicular activities, it may be virtually impossible to access a traditional keyboard and computer display to access an ETM.

For example, during a satellite repair mission, it would not be practical for an astronaut in a bulky extravehicular space suit to type commands on a keyboard to view a display in the extreme environment of outer space where the sun glare may make viewing impossible.

However, these systems, being a single user-to-computer paradigm, do not allow multiple-user access to multiple computers, multimedia devices or nodes on a network for accessing arbitrarily-selected data channels.

Further, these previously-described systems are self contained and their data storage needs to be updated periodically to be sure that the latest data is displayed.

Further, these systems do not allow two-way communication over local and wide area networks to other mutli-media users and devices, and do not provide real-time biomedical information about the physical condition of the user.
