To create scientific knowledge about how the precision of a tracking system interacts with the HCI design of a location based system.
Make a systematic empirical study of factors that influence the
precision of the Blip System for Bluetooth based tracking.
A tracking system is a system that is able in
real time to track the geographical location (e.g., x-y coordinate,
room, or zone) of mobile units. Any such system will have a limited
precision; for radio based systems this is caused by walls, floors,
furniture and people that block and reflect the radio waves, as well
as the radio protocols used.
The Blip System, based on the Bluetooth radio technology, is able to
track mobile units (e.g., phones) that have Bluetooth and are set to
visible mode. It performs tracking by a number of Blip nodes, each
of which is part of a Blip zone; whenever a Blip node detects the
radio signal from a Bluetooth unit appearing or disappearing, it
sends a signal to applications using the Blip System. Applications
can then provide location aware services, based on the zone
information thus captured.
A Blip zone is the area in which a mobile unit will be detected by a
Blip node in this zone. The size of a Blip zone is determined by
the signal strength with which the Blip nodes detect the mobile
units, and can be changed by adjusting it using a system
administration tool.
However, not much is known about the actual size and shape of the Blip zones in the IT University. The goal of this project is to make a scientific empirical study, considering, among other aspects, how these factors influence the mobile unit detection distance and delay:
