Research versus Design Paradigms positivism technical rationality rational problem solving © M. Rauterberg, TU/e phenomenology etc, e. g. “Vienna Circle” etc, e. g. “phase models” constructionism design as reflective practice etc, e. g. “idealism” etc, e. g. “hermeneutic”

Results from both Paradigms positivism limits assessment criteria © M. Rauterberg, TU/e constructionism attractors design solutions

Comparison of both Paradigms theories and models abstracting reality (t 1) concretisation reality (t 2) positivism : constructionism : {theory, model reality (t 1) = reality (t 2) reality (t 1) reality (t 2) © M. Rauterberg, TU/e

What is User-System Interaction about? Working domain Goal: Actual Performance => Desired Performance Working system user © M. Rauterberg, TU/e system

Interface Design or Interaction Design? user © M. Rauterberg, TU/e interaction system

USI link to Industry - marketing cycle market success commercial product Industry Design relevant knowledge analysis synthesis validation © M. Rauterberg, TU/e Interactive systems Science

USI Research Line - validation cycle Design relevant knowledge analysis • expert • formal method • user model • real end user empirical validation © M. Rauterberg, TU/e synthesis validation Interactive systems

USI Research Line - development cycle Design relevant knowledge analysis synthesis validation Interactive systems • concept • prototype • demonstrator • real system empirical validation © M. Rauterberg, TU/e

Conclusions • a coherent and powerful corpus of descriptors and technical terminology • a theoretical framework to investigate the interaction space • a rigorous validation method to prove the design relevant knowledge © M. Rauterberg, TU/e
