| Title: | Multimodal Interaction with a Wearable Augmented Reality System |
| Abstract: | Wearable computers have evolved into tremendously powerful and versatile devices: PDAs, cell phones with integrated video recorders, wristwatches, game consoles, and even garments with built-in computational power. Unfortunately, their human-interface capabilities have not evolved as rapidly. Rather, the devices’ continuously shrinking form factors severely limit their interfaces. Traditional interfaces, such as keyboards and LCD screens, can only be as big as a device’s surface. Fortunately, the conflicting goals of device size and interface area can both be met by expanding the interaction area beyond the device’s dimensions: augmenting the reality through head-worn displays allows for information visualization in the entire field of view, extending far beyond the display’s physical size. Equally, hand gestures performed in free space, recognized with a headworn camera, are not constrained to the hardware unit’s dimensions. Combining these advantageous I/O modalities harbors the promise of more complex interaction than what is possible with a keypad. In this article, we detail our experiences with various input devices and modalities and discuss their advantages and drawbacks in the context of interaction tasks in mobile computing. We show how we integrated the input channels to use the modalities beneficially and how this enhances the interface’s overall usability.
