“…sink correspondences, directionalizing, localizing, or spatializing each source to its best sink, a function of respective and mutual direction and orientation, directionality, and range. The apparent paradoxes of auditory multipresence can be resolved by an ''autofocus'' technique that uses Helmholtz reciprocity (exchangeability of sources and sinks) and simulated precedence effect (perceptual fusion) to disambiguate soundscapes [35], like a ''snap-to'' grid. Auditory interfaces can simulate ''superhearing'' including hyperacuity: hyperselectivity as well as hypersensitivity.…”

We present an analytical framework for a cognitively informed organization of signals involved in computational representations of spatial soundscape superposition, defined here as ''procedural superposition,'' building on the accompanying article Part I, where we discussed physical (acoustical) and perceptual (subjective and psychological) frameworks for soundscape representations in virtual auditory displays. Exploiting multimodal sensation and mental models of situations and environments, convention and idiom can tighten listeners' apprehension of an auditory scene, using metaphor and relaxed expectation of sonorealism to enrich communication. Besides physical and psychological combinations, procedural (logical and cognitive) superposition considers metaphorical mappings between audio sources and virtual location, including such aspects as separation of visual and auditory perspectives; separation of direction and distance; parameterized binaural and spatial effects, including directionality; range-compression and indifference; layering of soundscapes; ''audio windowing'' (analogous to graphical user interface windows), narrowcasting, and multipresence as a strategies for managing privacy; and rotation as revolution. These auditory display strategies leverage virtual relaxations of sonorealism to enable enhanced soundscape representation.

“…When going through experiences, players are often motivated through personal, contextual, and social objectives (Isbister, 2010), while capturing the world's aspects through their perspective in the given moment. An experience is defined by considering cognitive abilities (Nacke, 2015;Hodent, 2017), the context, and the environment the user is (Isbister, 2010;Cohen & Newton Fernando, 2009), how aesthetically pleasing the experience is perceived by the user (Calvillo-Gámez, Cairns, & Cox, 2015) and social influence with relatives (Isbister, 2010;Oulasvirta, 2009;Cohen & Newton Fernando, 2009). These elements guide developers to design pleasurable and enjoyable experiences for their customers.…”

“…It can be a vast and big forest with a character roaming through it, or it can just be a two-dimensional game. According to the literature, the concept of presence (Takatalo, Häkkinen, & Nyman, 2015;Cohen & Newton Fernando, 2009) employs "the sense of being there", even if said environment is entirely virtual. This connection is characterized by the player's sense of self-presence in the virtual environment.…”

“…It not only encompasses the ambiance the user is physically located, but it goes beyond it by also tackling a sense of identity, activities, and neighbors as well in the virtual ambiance. Notably, awareness can be addressed by three different types, as described by Cohen and Fernando (2009): presence, telepresence, and co-presence. As the name suggests, presence defines one's feeling of being part of the virtual environment.…”

The gaming industry has grown considerably in the last decades, designing experiences and interactive platforms through games, a popular culture entertainment medium. With the advancement of technologies and user experience design methods, a challenge is faced for the constant improvement of game characteristics aiming to improve pleasurability and immersion perceived by its users. To face this challenge, we designed a conceptual framework named GLIMPSE based on constructs used to evaluate user experiences with games. Its applicability was tested through a questionnaire that collected 241 valid responses from users of gaming forums and communities. An analysis was drawn to identify correlations between the data collected from the questionnaire, and its results revealed significant statistical data highlighting age and gender-wise differences from participants’ opinions.

“…With the "spread of wireless communication and the desire to travel 'light,' collaboration across mobile devices", such as phones, tables, and notebooks, is a likely trend for future groupware applications [3]. With the diffusion of mobile devices in the working landscape, there is an economic interest in using standard mobile devices to develop remote expert support [12].…”

Figure 1: Remote support for car drivers is typically offered as audio instructions only (left). This paper presents a mobile solutionincluding a sketch-and gesture-video-overlay (right). ABSTRACTUneven knowledge distribution is often an issue in remote support systems, creating the occasional need for additional information layers that extend beyond plain videoconference and shared workspaces. This paper introduces SEMarbeta, a remote support system designed for car drivers in need of help from an officebound professional expert. We introduce a design concept and its technical implementation using low-cost hardware and techniques inspired by augmented reality research. In this setup, the driver uses a portable Android tablet PC while the expert mechanic uses a stationary computer equipped with a video camera capturing his gestures and sketches. Hence, verbal instructions can be combined with supportive gestures and sketches added by the expert mechanic to the car's video display. To validate this concept, we carried out a user study involving two typical automotive repair tasks: checking engine oil and examining fuses. Based on these tasks and following a between-group (drivers and expert mechanics) design, we compared voice-only with additional sketch-and gesture-overlay on video screenshots measuring objective and perceived quality of help. Results indicate that sketch-and gesture-overlay can benefit remote car support in typical breakdown situations.
