Progress indicators provide information about downloading progress and the remaining time. Two common forms of indicator are bar and spinner. However, most studies have focused on the form of bar. Therefore, we are going to investigate which patterns of progress spinner show better perceived speed and satisfaction. Also the effects of provision of time information were studied. This study provided the progress spinner with different patterns with 4 seconds and 12 seconds download latencies. The participants evaluated overall satisfaction and perceived downloading speed. As a result, 'Speed Up' patterns showed the higher perceived downloading speed and satisfaction than 'Speed Down' patterns. In 4s situation, it was better with time information was absent. In 12s situation, it was higher in terms of the perceived downloading speed when time information was provided.
