Download Predicting User Performance and Errors: Automated Usability by Marc Halbrügge PDF

By Marc Halbrügge

This publication proposes a mix of cognitive modeling with model-based consumer interface improvement to take on the matter of keeping the usability of functions that focus on a number of equipment varieties straight away (e.g., computer workstation, clever cell, shrewdpermanent TV). Model-based functions offer attention-grabbing meta-information concerning the components of the person interface (UI) which are obtainable via computational introspection. Cognitive consumer types can capitalize in this meta-information to supply enhanced predictions of the interplay habit of destiny human clients of purposes below improvement.

In order to accomplish this, cognitive tactics that hyperlink UI homes to usability facets like effectiveness (user mistakes) and potency (task final touch time) are demonstrated empirically, are defined via cognitive modeling, and are verified during this treatise. when it comes to consumer errors, the e-book develops a longer version of sequential motion keep watch over in keeping with the reminiscence for pursuits thought and it really is proven in numerous behavioral domain names and experimental paradigms.

This new version of consumer cognition and behaviour is applied utilizing the MeMo workbench and built-in with the model-based software framework MASP with a purpose to supply computerized usability predictions from early software program improvement levels on. eventually, the validity of the ensuing built-in procedure is proven through empirical information from a brand new software, eliciting unforeseen behavioral patterns.
