Effects of RSVP Display Design on Visual Performance in Accomplishing Dual Tasks with Small Screens  

Rapid serial visual presentation (RSVP) represents a mechanism for exhibiting temporal information instead of spatial information to overcome the limitations of small-screen devices. Previous studies examining this area focused only on information presented by RSVP displays and disregarded changes in the performance of accompanying tasks associated with such displays. Therefore, this investigation performed a dual-task experiment (a search task for static information and a reading task for RSVP display information) to examine the effects of presentation mode (character-by-character, word-by-word, and one-line format), speed (171, 260, 350, and 430 characters per minute, or cpm), and text-flow orientation (vertical and horizontal orientation) of RSVP display information on the visual performance of users during different stages of usage (whether current usage is the first, second, third, fourth, fifth, or eighth day of usage) for a small screen.

Making the Right Constraints for Usable and Accessible User Interfaces

This paper focuses on managing constraints in a way that enables developers to create an accessible and usable user interface (UI). The constraining processes presented in this paper comprise of a language to describe a logical web page in an application, a basic bottom-up repository management system and the processing required for compiling pages.
