Abstract With the introduction of the metaverse, augmented reality (AR) is expected to become the next interface between people and computers. Research is conducted to improve the usability of AR applications and devices. Color transparency and background effect are the two critical factors to consider while developing AR applications. Ten user interface conditions (5 color transparency levels × 2 background conditions) were evaluated in an AR environment. The task completion time and mean error were noted along with the subjective scores of button visibility, background visibility, and motion sickness. The results revealed a significant difference in task completion time, button visibility, and background visibility between transparency conditions, but not in the number of errors and total motion sickness. The transparency level of T0.5 and T0.75 is recommended for the interface of AR applications. This study could be helpful when creating augmented reality applications for the metaverse and other platforms.

Abstract On social network platforms, people may edit their photos and alter personal information to build an online identity that is different from their offline identity. The increasingly close connection between the online and offline world may have some impact on the behavior of online identity reconstruction. This study explored the motivations for online identity reconstruction with personal interviews. Sixty-five university students participated in this study. Data were analyzed by content analysis method. We identified that people may reconstruct their identity due to vanity, self-confidence, bridging social capital, enjoyment, detachment, privacy concerns, and conformity. The motivations were interpreted based on Akers’ social learning theory. It is found that people’s social network (e.g., the individuals/groups around them) can influence their motivations for online identity reconstruction. The use of mobile technology also facilitates online identity reconstruction. This study contributes to the research on online identity reconstruction by taking into account the influence of people’s social networks and the effect of online-offline integration, providing a better understanding of motivations for online identity reconstruction.

Abstract The wearable device market is growing rapidly, as evidenced by the growth in sales of smartwatches. However, these have a tiny touch screen so users cannot perform complex operations with a smartwatch. Few studies address the user experience of gestures to interact with wearable devices. This study uses a bone-conduction smartwatch to study the user experience of gestures for interaction with a wearable device in terms of four dimensions: pragmatic quality, hedonic quality–identification and hedonic quality–stimulation and attractiveness. Task loads ae also evaluated for further analysis of the user experience This study determines the relationship between these factors to determine the effect of using hand gestures to interact with wearable devices. The results of this study show that all of the users easily accept gesture interaction with wearable devices. Pragmatic quality, hedonic quality–identification and hedonic quality–stimulation are positively associated with attractiveness. A higher level of attractiveness reduces the perceived task load. Attractiveness has a significant positive effect on performance and task load has a significant negative effect on performance.
