“…But it also shows the potential of improving the QoS of mobile video technology, whilst using the same bandwidth. Multimodal synergy has the potential to alleviate auditory and visual issues that emerged in parallel with mobile technology [10,29,31]. And, when enhancing and highlighting auditory, visual, and bimodal features that benefit multimodal synergy, this opportunity comes free of charge.…”

Available bandwidth is still a limiting factor for mobile communication applications. Multisensory communication has already been identified as an possibility to moderate this limitation. One of the strengths of mobile communication lies in its combination of visual and auditory modalities. However, one of the most salient features of mobile devices have are their small screen size. This paper explores how the potential for multimodal synergy relates to the small screen size. In an experiment with 54 participants, the intelligibility was tested using a standardized video-listening test. The videos had a signal-to-noise ratio of -9dB and were presented on three different screen sizes, whilst keeping the video and auditory signals equal. Intelligibility was found to be significantly higher when using a large screen in comparison to using either of both smaller screens. We conclude that multisensory synergy is key to mobile applications, yet that screen size is a substantial constraint to this synergy. We argue that knowledge about human sensory processing can alleviate this constraint and maximize the potential quality of service of mobile video technology.

“…Such facts reveal the importance to take into account individuals with diverse sensory abilities when developing new technologies [49]. The same application should be made as accessible to someone with an impairment as it is to someone without one; thus, preventing social exclusion [15,24,53].…”

Billions of people live with visual and/or hearing impairments. Regrettably, their access to systems remains delayed, leaving them socially excluded. The need for universal access of next-generation systems and users’ inclusion is paramount. We pose that a smart society should respond to this crucial need. Following ability-based design principles, we introduce a simulated social robot that adapts to users’ sensory abilities. Its working was assessed via a Rock–Paper–Scissors game in an Intelligent Environment (IE), using three modes: where the user is able to see and hear, only see, or only hear. With this game, two user-studies were conducted using the UMUX-LITE usability score, an expectation rating, and the gap between experience and expectation, complemented with two open questions. A repeated measures Multivariate ANalysis Of VAriance (MANOVA) on the data from study 1 unveiled an overall difference between the three modes, F ( 6 , 6 ) = 6.823, η p 2 = .872, p = .017. Users expected applications to be harder to use with a disability, especially a visual impairment. All modes were considered accessible, with the experience exceeding expectations for the mode with a hearing impairment. In parallel, substantial variance was observed across participants and the results from the open questions suggested improvements. To reduce this variance and increase system stability, study 2 was run with an enhanced design. A repeated measures MANOVA on the data from study 2 confirmed study 1’s findings, F ( 6 , 6 ) = 12.801, η p 2 = .928, p = .003. Moreover, experiences exceeded expectations in all modes and the variance among participants was substantially decreased. We conclude that IE applications managed by a social robot can be adapted to user’s sensory abilities, improving smart society’s accessibility, and, hence, reducing social exclusion.

“…Another study from WHO states that 2.2 billion people worldwide suffer from visual impairment 3 . Such high numbers reveal the importance to generalize Intelligent Environments (IE) applications to adapt to the capacities of every user, thus preventing social exclusion [1,2].…”

The number of worldwide inhabitants suffering from visual or hearing impairments reaches billions according to the World Health Organization, making the need for universal access and inclusion in Intelligent Environments (IE) essential. An adaptive Rock-Paper-Scissors application using a simulation of the social robot Haru is presented. The accessibility of the application which covers three modes - where the user able to see and hear, only to see, or only to hear – was verified through a user-study. A multivariate analysis of variance with repeated measures determined that the ratings from the 12 participants differed significantly across the three modes with F(6,6) = 6.823, η2p = .872, p = .017. Results show that users tend to expect applications to be harder to use when suffering from a disability, especially a visual impairment. All modes in the application were deemed acceptable in terms of usability, proving that the multimodality that comes with IE can help in promoting universal access and reducing social exclusion.
