Abstract

This paper aims to investigate the effects of steady-state visual evoked potential (SSVEP) in the aspects of viewing distance variation for a smart TV control system. We designed an experimental environments with different viewing distance. Four healthy people (age 27.5±1, male) participated in the experiment. Four visual stimuli with a round shape were designed and presented on LED monitor flickering in frequencies of 7, 9, 11, and 13Hz. Viewing distances were changed from 1m to 3m during the experiment. Moreover, we collected SSVEP signals with and without videos as a disturbance stimulus on the monitor to consider similar condition in real life environments. The canonical correlation analysis (CCA) method was used to analyze the frequency information of the acquired SSVEP signals. The averaged accuracies of all subjects were 71 ± 8.7% during without-video condition and 67 ± 14% during with-video condition. The results show necessity of stabilization in SSVEP system performance in environment even with increasing viewing distance.
