Roadmap: Wearable Computing 2020
Motivation
1. Access to high speed communication is becoming ubiquitous
2. Relevant information is available somewhere on the net for every conceivable situation
3. Information recording is desirable and possible in many situations
4. But the information is hardly used outside classical office environment
Conventional Computer
stationary
focused on the system
not immediately dealing with the environment

The Wearable Vision
• non disruptive interaction • environment oriented
– context recognition– augmentation
• physically unobtrusive• seamlessly connected

What is Wearable ?
• you wear clothing• clothing is something you need always and
everywhere– it does not disturb you – it is performing a useful function all the time
Wearable computing is technology that you use always and everywhere
A Prototypical Wearable Device
Hearing aid computer
•permanently useful•augments user‘s perception
•situation sensitive–adjusts amplification to the situation
•virtually unnoticeable
Key Architecture Question
What does integration with the outfit mean ?Observation: clothing is a heterogeneous,
distributed, dynamically reconfigurable system
– function – technology– user expectation
Solution: 4 layers of integration reflecting relation between clothing and electronic
Layer 1: Functional Textiles conductive fabric stripes
spacer fabric
Simple Functions in Textiles
textile wires forconnection of
ditributed sensornetworks
textile antennas(Bluetooth) for
communication withprocessing units (QBIC)
and external devices
electrical circuitsintegrated into fabricsfor preprocessing of
sensor dataDr. Tünde Kirstein

Layer 2: Embedded Microsystems
Miniaturized Sensors
(Bharatula, Ossevoort, Lukowicz, Tröster, 2004)
Layer 3: Attachable Peripherals
Head Mounted Displays and AR

Sensor Based Interfaces
ETH QBIC: Belt Integrated System
• buckle as computer housing
• belt as peripheral bus
– connectors
– batteries
– wireless adapter, storage etc.
