Abstract

Mobile and wearable devices place enormous constraints on input and display form factors as well as on user attention. The key to designing micro-displays is knowing what sizes and configurations are viable for keeping users informed, what flexibility different micro-displays provide for different types of messages, and the learning requirements on the user. An experiment was performed to measure user learning and comprehension of increasing amounts of information on a simulated three-light visual display. Users were required to learn five sets of messages of increasing information and complexity using the small display. Results show that micro-displays can transmit detailed, information-rich messages up to 6.75 bits with minimal training (i.e., few trials and short time frames).
