- Folding and very steep bending angles solution- Kinect sensors and projectors Makes a trade-off tracking stability & detectable deformations. Not suitable for: very sharp bends Particular folds Stretchable materials
- To evaluate the feasibility of the Flexpad approach, they conducted two evaluations, examining both system performance and the users’ ability of precise interaction with highly deformable displays. Test : 1.Tracking performance Volunteers use slicing-throughtime application and freely create interesting renderings by deforming the display. Recorded the raw video stream from the Kinect camera.calculating the RMS error . This shows that the tracking performs very adequately even in challenging realistic tasks. 2. User performance deformation evaluate how fast and precise users are able to perform deformations and to examine the influence of flexible vs. shape-retaining display materials. The result is users are capable of using highly flexible displays with ease. Users can make various single and dual deformations with both materials quickly and easily. Fully flexible material suited for simple deformations and preferred for the task of the controlled experiments. Shape-retaining materials well suited for complex deformation and analyzing curve phenomena but it introduce time penalty in shape creation.
- Touch input on deformable displays developing solutions for Kinect sensors to detect touch input reliably on real-time deformable surfaces more advanced techniques need to be developed, for instance based on the shape of the touch point or on the normal force involved to deform the display Active flexible displays Currently available projected display prototypes are still very limited in their flexibility, so that they cannot be used to realize our concepts. Given the rapid advancements in display technology Smart materials for flexible displays both fully flexible and shape-retaining displays have unique capabilities. A material that can programmatically switch between both of these states would combine all these advantages. Moreover, future work should examine handheld displays that, in addition to being deformable, are stretchable. This will further increase the expressiveness of interactions with flexible displays
