Interaction on Tactile Surfaces

F. Vernier, C. Perin, E. Pointal

Human-Computer Interaction is a very broad research field with many sub domains like "Computer Supported Collaborative Work", "Multimodal Interfaces" or "3D user Interfaces". Every domain share the scientific methodology of studying a couple "human(s) + computer". However every subdomain follow its own goals according to the interaction context it focus on.

Tactile Surfaces do not need to justify the technology feasibility (because millions of smartphone and tablet user prove it) or performances (it is well known tactile surfaces are less efficient than mouse). The main quest for tactile surfaces researchers is to find application domains where a large tactile surface makes more sense than the traditional mouse+keyboard+screen triple.


At LIMSI we already studied small scale 3D scene navigation in the previous time range (2009-2013) with the thesis of Rami Ajaj and we followed this way during the last 2 years with the Sustains project in a much larger scale. Instead of studying building/room scale size we enlarged studied scenes to the scale of a city. Sustains project aims at providing tools to help urban planner and politic decision makers while envisioning new cities or new urban neighborhoods. Unlike previous work we propose a dual coordinated view with 2D and 3D on the same tactile surface where users can smoothly interact between the 2D view (for panning and easy selection with no occlusion) and 3D view (rotating and zooming to achieve the desired point of view). Such partition of input becomes possible when surface is large enough and with enough resolution. It allows to keep a consistent interaction language inside the 2 views and among them while reducing the need for disambiguate gestures when they are nor performed on the same view.


Our second axis is about studying a new (more abstract) application domain with time series visualization.  Challenges with time series are numerous and there are two different approaches: merging the series to detect crossing or separating series to help detecting patterns by aligning the separated series. We contributed to both approaches with invention of GapCharts and StratumGraphs as well as proposing an interaction language well suited for tactile surfaces using selection and widget crossing.
