“…Demura and Uchiyama [35] supported our data by analyzing stride length and gait speed. Also, Lamberg and Muratori [12] reported in their recent experiment that multi-tasking results in cognitive distraction which slows gait speed and causes deviation from a straight path. Harbluk et al [36] discuss how pedestrians have a slowed gait speed because of their fear of facing obstructions and fear of a fall.…”

Objective: This study was conducted to test the effects of mobile texting and gaming on gait with obstructions under different illumination levels. Design: Cross-sectional study. Methods: Twelve healthy adults aged 20 to 36 years (mean 23.5 years) were tested under six different conditions. All participants used touchscreen smartphones. Testing conditions included: 1) Walking with an obstruction under a bright illumination level; 2) walking with an obstruction with a low level of illumination; 3) walking with an obstruction while texting under a bright illumination level; 4) walking with an obstruction while texting with a low level of illumination; 5) walking with an obstruction while gaming under a bright illumination level; and 6) walking with an obstruction while gaming with a low level of illumination. All participants were asked to text the Korean national anthem by their own phone and play Temple Run 2 using an iPhone 5. Gait variances were measured over a distance of 3 m, and the mean value after three trials was used. A gait analyzer was used to measure the data. Results: Compared to normal gait with obstruction, gait speed, step length, stride length, step time, stride time, cadence while texting and gaming showed significant differences (p<0.05). Differences between the illumination levels included gait speed, step length, stride length, and step time (p<0.05) with no significant differences in stride time and cadence. Conclusions: Dual-tasking using a smartphone under low levels of illumination lowers the quality of gait with obstructions.

“…As a result, multi-tasking cannot be used as a tool to measure the processing capacity level. Although safe walking requires both physical ability and sensory ability, multi-tasking (such as texting and gaming) disturbs the working memory and causes situational errors [12].…”

“…Individuals performing cognitive tasks while walking have a higher risk of collision and falling [32]. Pedestrians using mobile phones have a lack of situational cognition, and distracted and unstable actions increase [4]. Gait change with regard to mobile phone use threatens pedestrian safety [10].…”

Objective: The purpose of this study was to examine the influences on gait features during mobile phone use while ramp walking. Design: Cross-sectional study. Methods: Thirty-three healthy adult subjects performed four walking conditions on an outside ramp with a 5 m length, 1.5 m width, and a 5 o angle. All participants were touch screen mobile phone users. Four walking conditions were used: 1) ramp ascent,2) ramp descent, 3) texting during ramp ascent, and 4) texting during ramp descent. In conditions 3) and 4), subjects texted the words of "Aegukga"−the song of patriotism−while walking. Upon the signal of start, the subjects walked the ramp during texting. Gait parameters were measured at the length of 3 m excluding 1 m of the start and end of the total length. Each situation was repeated three times for each subject, and mean values were calculated. For gait examination, a gait analyzer was used (OptoGait). Results: Subjects ranged in age from 23 to 38 years (mean age, 27.73). Eighty-three percent of subjects in our study had experienced an accident during mobile phone use. Texting on a mobile phone while walking significantly decreased ramp gait, speed, cadence, stride length, step length, and single support (p<0.05) and significantly increased stride time, step time, gait cycle, and double support (p<0.05). There was a significant difference in cadence, step length, stride time, step time, and single support during ramp ascent and descent (p<0.05). Conclusions:Texting on a mobile phone while walking significantly decreased gait quality.

“…Foreign experts have made in-depth studies on pedestrian distraction [1][2][3][4][5][6], at the same time, they have made studies on different groups of people. The main research idea is to select the research object in the way of random sampling, then to further understand the walking habits, gender, age, race and so on of the research object, and carry out training on experiment courses.…”

Abstract. As for the traffic hidden danger generated by pedestrians when they are distracted while crossing the street, this study selects the typical area of the signalized and unsignalized crosswalk collects the data of them by artificial investigation and draws the conclusions. It is concluded that on the two types of crosswalks, people on the signalized crosswalks are more easily distracted. For different age groups of pedestrians, young people are more likely to have distraction behavior than middle aged people and old people. For different behaviors of distraction, the risk of traffic accidents from high to low are generated by using mobile phones to surf the Internet, making phone calls, listening to music, and concentrating on crossing the street. The study provides data support and basis for traffic management department to improve pedestrian safety.
