AR Tips: Augmented FirstPerson View Task Instruction Videos This research investigates applying Augmented Reality (AR) visualisation of spatial cues in firstperson view task instruction videos. Instructional videos are becoming popular, and are not only used in formal education and training, but even in everyday life as more people seek for howto videos when they need help with instructions. However, video clips are 2D visualisation of the task space, sometimes making it hard for the viewer to follow and match the objects in the video to those in the realworld task space. We propose augmenting task instruction videos with 3D visualisation of spatial cues to overcome this problem, focusing on creating and viewing firstperson view instruction videos. As a proof of concept, we designed and implemented a prototype system, called AR Tips, which allows users to capture and watch firstperson view instructional videos on a wearable AR device, augmented with 3D visual cues shown insitu at the task environment. Initial feedback from potential end users indicate that the prototype system is very easy to use and could be applied to various scenarios.

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.
