What is mobile use, and how should we evaluate it? We propose and motivate a variant of Heuristic Evaluation, based on the Locales framework, which has been specifically tailored for mobile devices. We report on the application of the 'Mobile Heuristic Walkthrough' approach to an experimental mobile appliance. Though useful, the evaluation results challenge us to be clearer about the nature of the 'mobile problem'. We finish with an initial attempt to define some issues germane to mobile use.
