Editor's Notes

• #3: At last years MobileHCI we presented a study about the usage of ML and SP interaction with a poster game in a public space. The driving question was … Goals: Formative: inform design of combined interfaces through observation in potential usage scenario ML: physical interaction, visually exposes both display and user more to the surrounding SP: allows for more private interaction, established way of navigating and interacting with content Which interface would be used longer?
• #4: TODO: Bring in comparative part lab-public H1: ML will be used less often in the public setting than in the laboratory
• #5: Hooray! Participants overwhelmingly used the ML interface and preferred it Not many significant differences lab – public space Lab sufficient? BUT 50% would not use it in public settings similar to the one they were in?

• #8: the potentially large number of confounding factors which can influence the evaluation outcomes. fatigue, the perceived severity of tracking errors, the role of personality (e.g., intro- and extraversion), intrinsic motivation to use the interfaces, the novelty of the ML metaphor and demand characteristics.
• #9: PUV: mainly waiting area Disadvantaged area Passers-by partly in peripheral view of partic. PUG: mainly transit area Central square under CCTV Passers-by behind partic.
• #10: PUV: mainly waiting area Disadvantaged area Passers-by partly in peripheral view of partic. PUG: mainly transit area Central square under CCTV Passers-by behind partic.
• #11: The PUG condition was carried out a location primarily used as transit area for changing tram lines with the major waiting areas being more than 20m away (see Figure 5). It was located in a wide open space in the city center. People from all social contexts are using this place for changing trams. The general area is under video surveillance and the building at which the study took place was actively operated by the local tram company. It was a place with a high frequency of passers-by coming from several directions but only a few people were standing in the social space of the participants (rather walking behind the participants, see Figure 5). In contrast the location in the PUV condition was primarily used as waiting area for people coming from the exit of a near-by metro line (see Figure 6). It was located in a disadvantaged area (Vienna Leopoldstadt). Comments of participants about the “shabby” area and experimenter’s observations indicate that there might have been a larger social distance between participants (mostly middleclass, students) and people with lower socioeconomic status present at the tram stop compared to PUG. Those differences between the locations could indicate that the social context in PUV could have inhibited the use of expressive, socially not common spatial gestures used in the ML interface, which is supported by the observations in Akpan et al. [1].
