A Discussion of User Experience on a Panoramic Scooter Riding Video Service This paper compares the user experiences (UXs) while riding a scooter on the road to watching a panoramic scooter riding video. The aim of this study is to determine whether using a panoramic scooter riding video service produces positive UXs for the riding experience as riding on a real scooter. Data were collected from an experiment involving a total of 34 individual scooter commuters. The participants were asked to watch a panoramic scooter riding video and to complete a user experience questionnaire (UEQ). The results verified that using the panoramic scooter riding video service may not be able to create scooter riding experiences for users. In order to enable widespread use of panoramic scooter riding video service in real life applications, a number of suggestions are proposed for the design of related services to strengthen the advantages of panoramic scooter riding video in simulated twowheeler ride experiences.

Effects of RealWorld Visual Fidelity on AR Interface Assessment: A Case Study Using AR Headup Display Graphics in Driving Recent AR research efforts have explored the use of virtual environments to test augmented reality (AR) user interfaces. However, it is yet to be seen what effects the visual fidelity of such virtual environments may have on AR interface assessment, and specifically to what degree assessment results observed in a virtual world would apply to the real world. Automotive AR headup (HUD) interfaces provide a meaningful application area to examine this problem, especially given that immersive, 3Dgraphicsbased driving simulators are established tools to examine invehicle interfaces safely before testing in real vehicles. In this work, we present an argument that adequately assessing AR interfaces requires a suite of different measures, and that such measures should be considered when debating the appropriateness of virtual environments for AR interface assessment. We present a case study that examines how an AR interface presented via HUD effects driver performance and behavior in different virtual and real environments. Twelve participants completed the study measuring driver task performance, eye gaze behavior and situational awareness during AR guided navigation in lowand highfidelity virtual simulation, and an onroad environment. Our results suggest that the visual fidelity of the environmental in which an AR interface is assessed, could impact some measures of effectiveness. Discussion is guided by a proposed initial assessment classification for AR user interfaces that may serve to guide future discussions on AR interface evaluation, as well as the suitability of virtual environments for AR assessment.
