Steps to take before Intelligent User Interfaces become

Steps to take before Intelligent User Interfaces become real by Kristina Höök 15. 10. 2002 Tiina Sarjakoski 1

Why we need Intelligent User Interfaces? Information overflow problems Help using complex systems Real-time cognitive overflow problems 15. 10. 2002 Tiina Sarjakoski 2

Problems: better usability methods intelligence to improve interaction better tools -> intelligent user interfaces aiding the computer-human interaction process 15. 10. 2002 Tiina Sarjakoski 3

1) Usability principles Control transparency and predictability – domain/ internal/embedding transparency Privacy and trust system takes tasks on from the user Treating systems as fellow beings shift user’s perception of responsibility agents providing right expectations 15. 10. 2002 Tiina Sarjakoski 4

Methods Meet the users’ needs A proper analysis of users 15. 10. 2002 Tiina Sarjakoski 5

Analysis phases in designing adaptive systems functional analysis data analysis task knowledge analysis user analysis environment analysis 15. 10. 2002 Tiina Sarjakoski 6

2) …Methods cognitive task analysis CTA by Roth and Woods, 1989 unreliable user characteristics individual differences linked to the problem user’s knowledge keeps changing 15. 10. 2002 Tiina Sarjakoski 8

3) Design practice Challenge: Improvement of interaction with the user Adaptive features/general usability Evaluating systems difficult 15. 10. 2002 Tiina Sarjakoski 9

4) Scalability Problem of AI systems: have not tackled the right problems New artificial intelligence: systems can learn and extend their coverage by themselves How to take into account new user interests, preferences -> combinations of human and machine intelligence, authoring tools 15. 10. 2002 Tiina Sarjakoski 10

Challenges: Summary Usability Development methods Useful adaptions Maintainability Design of systems must meet many different user groups’ needs Solutions rendered should actually solve the problems they claim to solve 15. 10. 2002 Tiina Sarjakoski 11
