Sandboxed interaction for casual users in shared spaces
Andrea Albarelli, Augusto Celentano · 2014
A simple and natural interaction is considered the most important feature of an interface for multiple impromptu users in public spaces. Intuitiveness and forthright feedback are key factors to enable a steep learning curve for untrained users that need to grasp the interaction model in a short time span. The lack of proper constraints, designed to restrict and guide the user actions, might hinder such intuitiveness, mainly when the number of users grows or their behavior is exceedingly unrestrained.
