The geodesign tools we used were based on the method of Arciniegas et al. (2011) to combine GIS, spatial multi-criteria analysis, and a touch-table to facilitate stakeholder dialogue in two workshops. A touch-table is an interactive touch screen, more recently developed as a large-scale (e.g., 46″, or 117 cm screen) tablet computer built in a table format that allows simultaneous input from up to 60 users while identifying which person is touching where. In this case study, we used a DiamondTouch table™, the physical setup of which consisted of the DiamondTouch device connected to a personal computer via USB cable, a video projector suspended above the table and aimed down onto the touch surface, and receiver mats (placed on chairs) connected to the DiamondTouch unit by cables. Only four participants could use this touch-table at any one time. We ran the device concurrently with ArcGIS® with the CommunityViz (www.communityviz.com) extensions for interactive planning to enable the presentation of map data and the spatial multi-criteria analysis. The touch-table provided the interface between the data and the workshop participants (Figure 15.2).

It is worth noting that enforced simultaneous interaction on a same interface element also depends on the kind of devices used. For example, systems implemented for DiamondTouch Tabletop (Dietz & Leigh, 2001) can enforce more interaction and collaboration from users because this device has recognizes the parts of its surface that are being touched. Thus, the system recognizes the actions of each user on the tabletop surface. In contrast, systems that utilize smaller form factors, such as iPads or other tablets, require an external mediator (i.e., a therapist) to prevent users from interfering with each other’s tasks. In addition, these types of systems do not support touch identification of multiple users. This means that one user could perform all the tasks by themselves, detracting from the collaboration. However, Boyd et al. (2015), suggest that these small devices have the advantage of closer proximity with the collaborators, which in itself can be a great contribution to the development of social skills in individuals with ASD.
