Shape-changing User Interfaces (UIs) explore the ability of a UI to change its physical shape to support multiple interaction modalities for users’ input and/or system’s output. An approach currently studied to implement such interfaces at a high resolution is based on mm-sized, round, and self-actuated modules. The problem we tackle in this paper...

Context 1
... sliders allow for several grasps. In particular, when the finger is on the central concave curve of the cursor ("curve" grasp, Figure 6), users can simultaneously control several sliders [5, p.140]. Thus, supporting this "curve" grasp is important. ...
Context 2
... only report here the grasp they settle on after the first target acquisition block or pursuit trial. We categorize the grasps we found in the three following categories of common grasps for physical sliders [23] (Figure 6, left): Curve is the grasp of the cursor with a single finger placed in the cursor's central concave curve; Pinch is the grasp of the cursor between two fingers, often the index and the thumb; Curve+Pinch is the grasp combining a pinch between one or two finger(s), often the middle and the thumb, and another finger, often the index, in the cursor's concave curve. ...
Context 3
... smooth slider and the slider with 1 mm modules present close performance for all three grasps ( Figure 6). The slider with 2.5 mm modules caused a higher error with the Curve grasp for the pursuit task (yellow in Figure 6). ...
Context 4
... smooth slider and the slider with 1 mm modules present close performance for all three grasps ( Figure 6). The slider with 2.5 mm modules caused a higher error with the Curve grasp for the pursuit task (yellow in Figure 6). The slider with 5 mm modules (orange in Figure 6) do not allow for the Curve grasp at all, while the Curve+Pinch grasp caused high error. ...
Context 5
... slider with 2.5 mm modules caused a higher error with the Curve grasp for the pursuit task (yellow in Figure 6). The slider with 5 mm modules (orange in Figure 6) do not allow for the Curve grasp at all, while the Curve+Pinch grasp caused high error. The Pinch grasp showed the best performance, although its accuracy with 5 mm modules is still far from the other sizes for the pursuit task. ...
