Ubicorder: A Mobile Device for Situated Interactions With Sensor Networks

Abstract

Abstract-The Ubicorder is a mobile, location and orientation aware device for browsing and interacting with real-time sensor network data. In addition to browsing data, the Ubicorder also provides a graphical user interface (GUI) that users can use to define inference rules. These inference rules detect sensor data patterns, and translate them to higher-order events. Rules can also be recursively combined to form an expressive and robust vocabulary for detecting real-world phenomena, thus enabling users to script higher level and relevant responses to distributed sensor stimuli. The Ubicorder's mobile, handheld form-factor enables users to easily bring the device to the phenomena of interest, hence simultaneously observe or cause real-world stimuli and manipulate in-situ the event detection rules easily using its graphical interface. In a first-use user study, participants without any prior sensor network experience rated the Ubicorder highly for its usefulness and usability when interacting with a sensor network.

A Context Menu for the Real World: Controlling Physical Appliances Through Head-Worn Infrared Targeting

“…Several approaches to spatial selection with handheld devices exist to control appliances [2,15,19,14] or to exchange information with smart infrastructure sensor networks [7,9,4]. Key design decisions are the method by which a target device is selected; and the method by which it is then later controlled or configured.…”

DoppelLab: Tools for exploring and harnessing multimodal sensor network data

“…The Tricorder [1] and Ubicorder [2] are a family of location-and orientation-aware handheld wireless sensor network browsers; the latter provides an interface for defining inference rules. Both systems feature a graphicallyaugmented 2-d floor plan.…”

TRUSS: Tracking Risk with Ubiquitous Smart Sensing

“…Several location-and orientation-aware handheld devices allow their users to move through the network, and provide interfaces for defining inference rules [11]. DoppelLab is a 3-d virtual environment for exploring multimodal sensor data and its relationship to architectural space [12].…”
