“…These were designed based on the state-of-the art interaction functions available in smartphones and tablets and with the goal to keep them as simple as possible (e.g., single click) and users were guided regarding the interactions available to them. We also paid attention that the users do not suffer from the so-called "gorilla arm" effect (Hansberger et al, 2017), that is, they would not have to hold the phone/tablet away from their body for extended amounts of time, which is ergonomically sub-optimal (the shoulders/arms/neck hurts).…”

“…Another challenging aspect of designing location based MR games (or interactive stories) is the interaction design (Çöltekin et al, 2020). Interaction design is challenging in all of XR (virtual, augmented and mixed reality systems); however they might be even more challenging for smartphones and tablets where the users need their hands to hold the device as opposed to those that are head-mounted (Hansberger et al, 2017). Current research demonstrates that MR-based (serious) games can be attractive and engaging (Dirin, Laine, 2018); although the current technology is laden with a number of human-computer interaction challenges (Stephanidis et al, 2019).…”

Abstract. With increasing technical feasibility of extended reality (XR) on smartphones and tablets, we also witness increasing versatility in the use of the mixed reality (MR) (i.e., rather than augmented or virtual) in utility-oriented apps (e.g., for navigation, indoor/outdoor spatial planning, entertainment and location based gaming. In cases where user adaptation and adherence is important, the design of the story itself, visualization and interaction in the game must be engaging, and ideally support spatial knowledge acquisition. In this paper, we briefly review the literature on creating engaging MR experiences for a location based game, and present a case study in which we feature a location based MR game (SBB Stories). We conceptualized, designed and implemented the SBB Stories with user-centered design methods in collaboration with the SBB (Swiss Federal Railways). In this paper we feature an interactive story that took place in Zurich’s main train station in 1937. Our findings from several cycles of user studies shows an increased spatial awareness of the surroundings as participants used the SBB Stories app. Importantly, participants reported the blending of historical and current visual elements as an outstanding and inspiring experience. Besides a high score of 83.75/100 in a standardized usability test, and a similarly high score of 4.25/5.00 in a standardized user engagement scale, all participants reported that they would spend extra time at the train station to play this game, suggesting that the app was indeed engaging.

“…Finally, previous works on KLM extensions modeled smartphonebased interactions. Combining touchscreens with HMDs could be useful to overcome mixed reality mid-air interaction problems, such as fatigue [15,16,18], limited accuracy [38] and gesture discoverability [3]. To this end, it will also be interesting to extend our KLM model with operators for smartphone-based interactions (cf.…”

“…The gorilla arm syndrome originally arose with the advent of touch and mid-air gestural interface, which force users to extend their arms without support. This can cause arm fatigue and a feeling of heaviness in the arms [ 20 ]. This does not mean that mid-air gestures should always be avoided [ 21 ].…”

In this work, we explore the role of augmented reality as a meta-user interface, with particular reference to its applications for interactive fitting room systems and the impact on the related shopping experience. Starting from literature and existing systems, we synthesized a set of nine interaction design patterns to develop AR fitting rooms and to support the shopping experience. The patterns were evaluated through a focus group with possible stakeholders with the aim of evaluating and envisioning the effects on the shopping experience. The focus group analysis shows as a result that the shopping experience related to an AR fitting room based on the proposed patterns is influenced by three main factors, namely: the perception of the utility, the ability to generate interest and curiosity, and the perceived comfort of the interaction and environment in which the system is installed. As a further result, the study shows that the patterns can successfully support these factors, but some elements that emerged from the focus group should be more investigated and taken into consideration by the designers.
