“…For example HearSay [16] is a non-visual web browser, where users collaboratively and voluntarily assign a label to each web page element using keyboard shortcuts or voice commands. These labels are stored in both local and remote repositories and shared with other users.…”

In this paper we present the design process and some interesting field t r ial r e sults o f t w o d i fferent game applications, designed and developed in order to extend and motivate the community of mPASS. mPASS is an urban accessibility mapping system that allows citizens to collect reliable data about barriers and facilities via crowdsourcing and crowdsensing and it uses these data to calculate accessible paths. On the one hand mPASS needs to collect a sufficiently dense, detailed and trustworthy amount of data. On the other hand, the community interested in obtaining accessible paths is not big enough to reach the critical mass of information needed by the system in order to provide effective services. To overcome this problem, we investigated gamification strategies in designing two mobile applications targeting young adults walkers, aimed to enlarge the data contributors community. The design process and field trial results of both games are presented, highlighting the design decisions resulted from feedback sessions, focus groups and experience prototyping.

At layer (6), generic document knowledge is employed to identify logical objects such as tables, lists, and grids. Layer (7) uses web specific knowledge to identify logical objects such as navigation menus or pagination elements sharing common web patterns.…”

On today's Web, designers take huge efforts to create visually rich websites that boast a magnitude of interactive elements. Contrarily, most web information extraction (WIE) algorithms are still based on attributed tree methods which struggle to deal with this complexity. In this paper, we introduce a versatile model to represent web documents. The model is based on gestalt theory principles-trying to capture the most important aspects in a formally exact way. It (i) represents and unifies access to visual layout, content and functional aspects; (ii) is implemented with semantic web techniques that can be leveraged for i.e. automatic reasoning. Considering the visual appearance of a web page, we view it as a collection of gestalt figures-based on gestalt primitives-each representing a specific design pattern, be it navigation menus or news articles. Based on this model, we introduce our WIE methodology, a re-engineering process involving design patterns, statistical distributions and text content properties. The complete framework consists of the UOM model, which formalizes the mentioned components, and the MANM layer that hints on structure and serialization, providing document re-packaging foundations. Finally, we discuss how we have applied and evaluated our model in the area of web accessibility.

In this research we introduce the ABBA 1 framework for the generation of advanced screen readers. Current solutions do not enable blind users to participate in the Web in a satisfactory way because they are not time-efficient, cumbersome to use, and do not provide enough overview and orientation within a document. Also, they hide away important layout information from the user. Our approach overcomes these limitations by unifying different semantic views of a document into one multi-axial model and making them accessible to the user in an intuitive interface. The benefit to the user is a higher level of control in different navigation scenarios.
