Location-Aware Information Delivery with ComMotion
comMotion is a location-aware computing environment which links personal information to locations in its user's life; for example, comMotion reminds one of her shopping list when she nears a grocery
Nomadic radio: speech and audio interaction for contextual messaging in nomadic environments
TLDR
Iterative design and a preliminary user evaluation suggest that audio is an appropriate medium for mobile messaging, but that care must be taken to minimally intrude on the wearer's social and physical environment.
Indoor location sensing using geo-magnetism
TLDR
An indoor positioning system that measures location using disturbances of the Earth's magnetic field caused by structural steel elements in a building that demonstrates accuracy within 1 meter 88% of the time in experiments in two buildings and across multiple floors within the buildings.
The audio notebook: paper and pen interaction with structured speech
TLDR
A new device-the Audio Notebook-for taking notes and interacting with a speech recording, a combination of a digital audio recorder and paper notebook, all in one device.
DuoSkin: rapidly prototyping on-skin user interfaces using skin-friendly materials
TLDR
DuoSkin is presented, a fabrication process that affords rapidly prototyping functional devices directly on the user's skin using gold leaf as the key material, a commodity material that is skin-friendly, robust for everyday wear, and user-friendly in fabrication.
ReachMedia: on-the-move interaction with everyday objects
TLDR
A system for seamlessly providing just-in-time information for everyday objects, built around a wireless wristband with an RFID reader to detect objects that the user is interacting with, showing 95% classification rate using the realtime online classification system.
Spatial input/display correspondence in a stereoscopic computer graphic work station
An interactive stereoscopic computer graphic workspace is described. A conventional frame store is used for three-dimensional display, with left/right eye views interlaced in video and viewed through
Nomadic radio: scaleable and contextual notification for wearable audio messaging
TLDR
Scaleable auditory techniques and a contextual notification model for providing timely information, while minimizing interruptions are described and demonstrated in Nomadic Radio, an audio-only wearable computing platform.
Dynamic Soundscape: mapping time to space for audio browsing
TLDR
This paper presents a browsing environment that provides a spatial interface for temporal navigation of audio data, taking advantage of human abilities of simultaneous listening and memory of spatial location.
Mime: compact, low power 3D gesture sensing for interaction with head mounted displays
TLDR
Mime introduces a real-time signal processing framework that combines a novel three-pixel time-of-flight (TOF) module with a standard RGB camera that achieves accurate 3D hand localization and tracking, and it thus enables motion-controlled gestures.
