Diplomarbeit: Usability engineering for ubiquitous

computing (augmented reality & tangible computing)

Supervisor: Christian Sandor

<Chris Kulas>

<kulas@in.tum.de>

11. November 2002 1

Chris Kulas (Usability)

• Up to the present day usability research for new-generation human-computer interfaces often neglected

Technology comes first• Why usability engineering?

obtain usable, useful products• Focus on usability evaluation• Rough life-cycle of usability engineering:

( Req. analysis / specification implementation / prototypes evaluation )*

11. November 2002 1

Chris Kulas (Usability) cont.

• Goal: Development of an evaluation framework which can be applied to future projects at the institute Deliverable: Usability Evaluation HOW-TO

1 Evaluation framework will be applied on ARCHIE (“sample”) in a larger (about 30 participants) evaluation environment

2 Rough structure of thesis:– Foundation (introduction, terms, basic design

guidelines)– “Software” engineering (RA, SD, IMPL)– Sample ARCHIE (application, recommendations)

<toennis@in.tum.de>

11. November 2002 1

Thesis: Data Management

One World – One Model

A dilemma:

• Presently, DWARF only supports scene models inside the views

• User interaction only modifies view's scene graph• Consistency between different views can just be done by

large Applications upon DWARF• A framework needs an organized data management

MarcusTönnis

11. November 2002 1

Thesis: Data Management

Data management• One model holding all built structural shapes minimizes

applications and enriches DWARF functionality.

Requirements:• Intelligent distribution of model data for reduzing

middleware load• Efficient update mechanisms for fast refreshes in views

MarcusTönnis

11. November 2002 1

Thesis: Data Management (cont.)

Additional issues:• Different users want to see varying views• Current used browsers do not support persistent storage of

dynamic changing models• Developing work requires history and templates• Default handling of different browsers

MarcusTönnis

11. November 2002 1

Thesis: Data Management (cont.)

Goals of Thesis:• Discovering efficient ways to keep a distributed system

without a bottleneck• Design and implementation of a component for the DWARF• Verifying this work within the ARCHIE project

Diplomarbeit: Calibration

What is calibrating needed for?• For ARCHIE user interfaces a calibrating routine is

needed• Calibrate the user input devices as comfortable as

possible

11. November 2002 1

Diplomarbeit: Calibration

The Problem:• How to overlay the virtual object with the real

object?

11. November 2002 1

Diplomarbeit: Calibration

Goals of thesis:• Adjust the available tracking components

• Enhance SPAAM (Single point active alignment method)

• Calibrate virtual cameras– See-through HMD (polarization, shutter glasses)– See-through laptop

• For the use of ARCHIE and other DWARF applications

11. November 2002 1

SEP: Security Model for DWARF• Security Model: Access Control• Why do we need Access Control ?

– All services in DWARF have equal access privilieges– ARCHIE defines different roles (architect, customer,

construction engineer)– This roles have different access priviliges to the world

model• What do we need ?

– We need a possibility to map these roles to allowed tasks

– It should be ensured that only authorized entities (persons, services) can connect to the system

SEP: Driver development for TouchGlove input device

11. November 2002 1

SEP: TouchGlove driver development

• What is the TouchGlove ?– New Input device developed by Columbia University– Designed as indoor and outdoor device– Free hands while working

• Our Problem:– No driver for Linux and Mac OS X available

11. November 2002 1

SEP: TouchGlove driver development

• Goals of the SEP:– Development of a low level driver communicating with

the TouchGlove over serial port– Implementation of a TouchGlove interpreter, which turns

the raw data of TouchGlove into DWARF-usable events– Development of a visual tool for generating interpreter

profiles– Development of a tool for visualizing the TouchGlove

activities– Testing the TouchGlove in the ARCHIE scenario

SEP: Design of a 3D Viewer for DWARF

11. November 2002 1

SEP: Design of a 3D Viewer for DWARF

Why is a new Viewer needed?• Available Solutions mostly are “only” Browsers. • Most Browsers have been designed for Desktop or VR

Applications.• Non of the Browsers is available for all Plattforms.• Different Standards for each Browser.

What do we need ?• Crossplattform Solution.• Viewing AND Interaction. Matching requirements for

distributed Systems.• Easy to Use and to Configure.• Re-Useable.

11. November 2002 1

SEP: Design of a 3D Browser for DWARF

Goals of the SEP:• Evaluation of Graphics Standards especially Open

Inventor vs. OpenSG.• Implementation of a Browser based on the chosen

Standard.• Specification and Classification of Objects and

Interaction in AR Environments• Test the Component in the ARCHIE context.
