• * Permit easy reversal of actions
• * Support internal locus of control* Reduce user's short term memroy load

• * Technology Induced Error and Usability: Errors when using a handheld application. [International Journal of Medical Informatics. 2005]

Heuristic evaluation is done as a systematic inspection of a user interface design for usability. The goal of heuristic evaluation is to find the usability problems in the design so that they can be attended to as part of an interative design process.
