“…When reviewing the bibliographic summary performed by Cáliz and collaborators, it was possible to identify 98 scientific contributions for usability studies with mobile devices [55]. Out of these, only five had been performed taking into account individuals with DS: Nacher and collaborators studied interaction on touchscreen devices, but only reviewed four gestures [24]; and Mendoza and his collaborators analysed how the eight most commonly used touchscreen gestures are learnt by teenagers with DS [61].…”

There has been a conscious shift towards developing increasingly inclusive applications. However, despite this fact, most research has focused on supporting those with visual or hearing impairments and less attention has been paid to cognitive impairments. The purpose of this study is to analyse touch gestures used for touchscreens and identify which gestures are suitable for individuals living with Down syndrome (DS) or other forms of physical or cognitive impairments. With this information, app developers can satisfy Design for All (DfA) requirements by selecting adequate gestures from existing lists of gesture sets. Twenty touch gestures were defined for this study and a sample group containing eighteen individuals with Down syndrome was used. A tool was developed to measure the performance of touch gestures and participants were asked to perform simple tasks that involved the repeated use of these twenty gestures. Three variables are analysed to establish whether they influence the success rates or completion times of gestures, as they could have a collateral effect on the skill with which gestures are performed. These variables are Gender, Type of Down syndrome, and Socioeconomic Status. Analysis reveals that significant difference is present when a pairwise comparison is performed, meaning individuals with DS cannot perform all gestures with the same ease. The variables Gender and Socioeconomic Status do not influence success rates or completion times, but Type of DS does.

“…In [3], the authors presented a process for usability testing for users with Down syndrome, which consists in 9 phases: recruiting participants, establishing tasks, writing instructions, defining test plan, pilot testing, refining test plan, testing, analyzing collected data, and presenting the results. It was made from a previous literature review.…”

Transportation, Health, and Entertainment are just a few areas of mobile technology application. Nevertheless, there are still some people who find difficulties using it. Although there are a lot of applications of mHealth available for almost any kind of mobile device, there is still a lack of understanding and attending users' needs, especially those of users with disabilities. People with Down syndrome have the potential to function as active members of our society, taking care of themselves and their own, having jobs, voting, and so on, but their physical limitations prevent them from handling correctly technological tools that could enhance their performance, including mobile technology. In this paper, we had analyzed how suitable the mHealth applications are for users with Down syndrome. We tested 24 users and analyzed their physical performance in fine-motor movements while developing a set of tasks over a mHealth application. Results showed that the design of a mHealth application for users with Down syndrome must center its interaction with simple gestures as tap and swipe avoiding more complex ones as spread and rotate. is research is a starting point to understand the fundamentals of people with Down syndrome interacting with mobile technology.

“…Despite these changing figures, it is nonetheless important to identify those characteristics that prove significant in order to ensure the creation of inclusive technology. Cáliz [8] is of the opinion that research involving usability testing with DS and similar disabilities is on the increase, and will continue to increase in the future.…”

Hand Gestures in Virtual and Augmented 3D Environments for Down Syndrome Users

et al. 2019

Studies have revealed that applications using virtual and augmented reality provide immersion, motivation, fun and engagement. However, to date, few studies have researched how users with Down syndrome interact with these technologies. This research has identified the most commonly used interactive 3D gestures according to the literature and tested eight of these using Oculus, Atheer and Leap Motion technologies. By applying MANOVAs to measurements of the time taken to complete each gesture and the success rate of each gesture when performed by participants with Down syndrome versus neurotypical participants, it was determined that significant difference was not shown for age or gender between these two sample groups. From the results, a difference was only demonstrated for the independent variable Down syndrome when analysed as a group. By using ANOVAs, it was determined that both groups found it easier to perform the gestures Stop, Point, Pan and Grab; thus, it is argued that these gestures should be used when programming software to create more inclusive AR and VR environments. The hardest gestures were Take, Pinch, Tap and Swipe; thus, these should be used to confirm critical actions, such as deleting data or cancelling actions. Lastly, the authors gather and make recommendations on how to develop inclusive 3D interfaces for individuals with Down syndrome.
