Heuristics for Mobile phones Dave Maruszewski & Shirley Carvalhedo

Heuristics for Mobile phones  Mobile interactions are often small steps in part of larger user goals. Many interactions must be intuitive and rapid. For example, if we are searching for an address when late for an appointment, we will have a low threshold for learning, registering or other obstacles to retrieving the data and locating our destination.

HEURISTIC GUIDE FOR MOBILE DESIGN  All mobile interactions are user-driven  New mobile experiences compete with legacy user Models  Ease of use is paramount  Calm technology will be valued over constant disruptions  The device as continuous companion opens the realm for mobile experiences of different intensities and durations  Mobile interactions can extend beyond the device  Mobile interactions are often small steps in part of larger user goals  Peer-to-peer is the most trusted form of mobile marketing  With GPS on the near horizon, the mobile phone will be able to provide services that redefine our social networks and the places we inhabit  Mobile phones will not be limited to the processing capabilities of the device

Do One Thing and do it well iPhone UI Design

Apple-Style drink the Apple UI kool-aid

The 80/20 Rule fewer features = better experience “At least 80 percent of your users will use a very limited number of features in an application, while less than 20 percent will use all the features.”

UI Elements as Real Objects “When possible, model your application’s objects and actions on objects and actions in the real world.” use what your users know

Multi-Touch Ergonomics give your users the finger “Provide a fingertip-size target area for all tappable elements.” “Put most frequently used information near the top, where it is most visible and accessible.”
