Wearable Heads-up Display With Integrated Finger-tracking Input Sensor

Abstract

Disclosed are systems, methods, and devices for interfacing with a wearable heads-up display via a finger-operable input device. The wearable heads-up display may include a display element for receiving and displaying display information received from a processor, and may also include a wearable frame structure supporting the display element and having a projection extending away from the display element. The projection may be configured to secure the heads-up display to a user's body in a manner such that the display element is disposed within a field of view of the user. A finger-operable input device secured to the wearable frame structure is configured to sense at least one of a position and movement of a finger along a planar direction relative to a surface of the input device, and to provide corresponding input information to the processor.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]The present application claims priority to U.S. patent application Ser. No. 13 / 115,430, filed on May 25, 2011, the entire contents of which are herein incorporated by reference.BACKGROUND[0002]Unless otherwise indicated herein, the materials described in this section are not prior art to the claims in this application and are not admitted to be prior art by inclusion in this section.[0003]Various technologies can be utilized to display information to a user of a system. Some systems for displaying information may utilize “heads-up” displays. A heads-up display can be incorporated into a pair of goggles, glasses, a headband, a helmet, or other such device that the user can wear. A heads-up display is typically positioned near the user's eyes and calibrated and / or aligned to the user's field of view to allow the user to review displayed information with little or no head movement. The display may also be transparent or translucent, allowing ...

AI Technical Summary

Benefits of technology

[0011]In another embodiment, the input device may include a touch-sensitive pad configured to sense at least one of a position and movement of a finger along a planar direction relative to a surface of the input device via capacitive sensing, resistance sensing, and / or via a surface acoustic wave (SAW) process. In yet another embodiment, the input device may be an optical imaging device and the surface of the optical imaging device a lens provided at an outer surface of the optical imaging device. By capturing images many times per second, the optical imaging device can accurately detect a position and movement of a finger along a planar direction relative to the lens surface of the input device.

Problems solved by technology

Further input could cause further updates to the display information or may cause the processor to execute other functions.

Due to the location of the finger-operable input device(s) on the stern of the glasses, the stems and / or input devices may block or hinder the peripheral vision of the user and / or block light from reaching a user's eyes.
