Usability evaluation of dynamic RSVP interface on web page

Abstract

The usability of rapid serial visual presentation (RSVP) interface was evaluated using subjective preference questionnaire and performance measurement methods. Forty-two students voluntarily participated in this study. The results indicated the shelf interface moving from bottom-left to upper-right along a linear trajectory with moving speed of 20∼30 frame per second (FPS) are most preferable. The carousel interface following circular trajectory in clockwise with moving speed of 10∼15 FPS are most preferable. "Meets user experience", "aesthetic and simple design", "effective to use", and "easy to learn" all conform to the usability goals. In addition, the results based on performance measurement showed a logistic regression model with RSVP mode and moving speed are fitted very well. There is the highest probability estimation of correct recognition for the carousel interface and moving speed of 30 FPS, however, the shelf interface and 15 FPS has the lowest probability estimation of correct recognition. © 2009 Springer Berlin Heidelberg.
