Human-Computer Interaction: why the technical side
Growing awareness of importance of HCI Quest for better user experience, higher productivity, more
reliable system, usable and useful interfaces,… New application domains, new or improved systems and
interaction devices, better graphics,…
3
Human-Computer Interaction: why the technical side
IBBT progresses the state-of-the-art in HCI for end-users, software developers and interface
designers before, during and after the development process
4
Overview HCI competences in IBBT
Model-Based User-Interface Design/Development HCI in Mobile, context-aware and pervasive systems HCI in Interactive Collaborative Workspaces 3D/multimodal interaction techniques Standardization Tool support and code frameworks Enabling technologies for multimodal interaction

Interactive Collaborative Environments
User interfaces, interaction techniques and visualizations forcollaborative work
16
Multimodal Interaction in 3D environments
Use of different modalities Eg haptics, speech,… Validation through usability testing
17
Multimodal interaction in virtual environments
Design of interaction techniques E.g. by making use of proprioception

Toolkits and Frameworks
Cutting edge user interface toolkits Zoomable User Interfaces Speech API Mobile UI Toolkits XML-based interface
rendering toolkits UI on multiple devices:
Java + OSGI, .Net + UIML,… Prototyping tools UML-based tool support Haptics Gesture tracking …

Conclusions
Sensible User InterfaceEngineering User-Centered Improve user
experience Meet the
requirements Both progressing the
state-of-the-art as wellas being pragmatic(focus on user)
