PC-based Control, Software and Bus Trendssystem. The device could enhance maintenance and service proceduresusing features such as eye movement detection, speech recognition andvisual input capability.The eyeglasses are based on traditional safety glasses and providethe wearer with audio and video interaction to a host system. Theglasses could contain sensors to detect eye movement, a microphone tohandle speech input for speech recognition and a miniature camera toallow visual inputs. The ear pieces could contain the power supply,neural net and other processors. Audio feedback could also be part ofthe combination.The user would be able to communicate with the device via naturalspeech, eye movement, or even mental feedback with the appropriatedetectors for alpha waves or other brain signals. Feedback would be inthe form of a retinal display projected into the eye or speech synthesisamplified from a small speaker.A high-resolution digital video camera would be located on thenose bridge. The camera would have to include some type of electronicfocus and iris, as well as enough pixels to allow software to scale theimage up (magnify) without losing details in blocks of pixels.The camera would provide a high-resolution view to central maintenanceto communicate what is being seen to support staff or intelligentagents (bots). The camera could also provide visual assistance by sendingmagnified, infrared, or thermal images directly to the retinal displaysystem.The eyeglass stems could hold the power supply and the localprocessor. A rechargeable battery takes up about one-half this area. Tohandle the image and audio processing, the computer unit would containa Neural-Net Processing Unit (NNPU) as well as conventional nonvolatilestorage and CPU arrays.Located at the ends of the ear pieces, the communications systemwould provide all communications including voice, wireless network,and mental feedback. The circuits also could monitor the vital signs ofthe wearer in the event of an emergency.Images from the camera or communicated from the host over awireless link would be fed to the retinal display system. The systemprojects from the side of the safety glasses into the lens, reflecting backto the user’s eye.This type of system should be able to provide a resolution of about3000 pixels by 5000 pixels in each eye. The system also monitors eye©2001 by The Fairmont Press, Inc. All rights reserved.
