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

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 computerpermanently usefulaugments users perception

situation sensitiveadjusts 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 expectationSolution: 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. Tnde Kirstein

Smart Shirts

Wearable Motherboard, Smart Shirt (GATECH)

Layer 2: Embedded Microsystems

Miniaturized Sensors

(Bharatula, Ossevoort, Lukowicz, Trster, 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.
