Augmented reality overlays computer generated imagery onto the real world to enhance a person's perception of the world. However the perceptual problems in augmented reality and virtual reality systems may affect human performance in information visualization. With improvements in technology, it is now easy to make use of motion to visualize change of quantitative data. Past studies have shown that representational momentum can influence the judged final position of a moving target. This study investigated human performance in visualizing dynamic quantitative information in augmented reality and virtual reality environments. Twenty-four subjects participated the experiment to estimate the percentage change of vibrating bar charts. Experimental results showed that subjects performed significantly different in different speed and percentage change. Visual momentum might affect the accuracy of estimation in visualizing dynamic quantitative information.
