“Text walking” often seen in town has been recognized as a social problem that may cause serious accidents due to a lack of attention to the surroundings. During “text walking”, user’s head moves together with the smartphone, which potentially causes another problem, namely maladaptation of the vestibulo-ocular reflex (VOR). The function of the VOR is to stabilize the field of view as our head moves. Its performance is characterized by VOR gain defined as eye velocity / head velocity. If head motion and motion of a visual pattern like one on a smartphone continue to occur in the same direction, VOR gain decreases, while VOR gain increases if they move in the opposite direction. The performance of the VOR has a significant impact on our visual perception while performing sports, and any other activities accompanying head motion. In this study, we evaluated effects of text walking on VOR performance by conducting a text walking experiment on a treadmill in combination with virtual reality visual motion. As a result, an increase in VOR gain is found in the high frequency band (above 4.0 Hz) after text walking for 10 min. In addition, at higher frequencies, the phase of the eye movement relative to the head movement tended to advance. These results indicate that text walking causes changes in VOR performance in the frequency band contained in various sports and daily activities. Thus, text walking may result in poorer performance of athletes and others requiring precise visual perception and visuo-motor transformation during their activities. |
