“…However, the stiffness, thickness and weight of the prototype are far from a real/future flexible tablet. As these properties influence interaction [5], they should be investigated in a new experiment with more realistic material.…”

Non-linear perspectives have the potential to improve 3D scene perception by increasing the information bandwidth of 3D contents. As with the example of the Mercator projection of earth, they can reduce occlusions by showing more of the shape of an object than classical perspectives. However, an ill-advised construction of such "usually static" perspectives could make the original shape difficult to understand, drastically reducing the scene comprehension. Yet, despite of their potential, these perspectives are rarely used. In this paper we aim at making non-linear perspectives more widely usable on mobile devices. We propose to solve the understanding issue by allowing the user to control the transition between linear and non-linear perspectives in real-time with bending gestures. Using this approach, we present the first user study that investigates real-time manipulation of non-linear perspectives in an exploration task. Results show significant benefits of the approach, and give insights on the best bending gestures and configurations. CCS CONCEPTS • Human-centered computing → User studies.

“…It is possible to grab, fold, or rotate the display in arbitrary ways, whereas the physical properties of the cloth are not influenced by the technical setting. In contrast to previous work, InformationSense therefore allows for unrestricted deformations and does not limit interaction to bending (e.g., [2,9,13,22,25,33,37]), stretching (e.g., [35,41,43,46]) or predefined folding (e.g., [8,18,24]) of the device. The technical setting of InformationSense uses a depth camera and a projector mounted on the ceiling.…”

Deformable displays can provide two major benefits compared to rigid displays: Objects of different shapes and deformabilities, situated in our physical environment, can be equipped with deformable displays, and users can benefit from their pre-existing knowledge about the interaction with physical objects when interacting with deformable displays. In this article we present InformationSense, a large, highly deformable cloth display. The article contributes to two research areas in the context of deformable displays: It presents an approach for the tracking of large, highly deformable surfaces, and it presents one of the first UX analyses of cloth displays that will help with the design of future interaction techniques for this kind of display. The comparison of InformationSense with a rigid display interface unveiled the trade-off that while users are able to interact with InformationSense more naturally and significantly preferred InformationSense in terms of joy of use, they preferred the rigid display interfaces in terms of efficiency. This suggests that deformable displays are already suitable if high hedonic qualities are important but need to be enhanced with additional digital power if high pragmatic qualities are required.

“…Aside from the display-oriented nature of most research, another reason for the particular focus on planar form-factors derives from currently available flex-detection technology. Planar-shaped bend sensors-either thin-film resistive sensors [7,12,16,29,42,52], or planar strain gauges [1,7], are overwhelmingly the most common method of detecting bend interactions in HCI research. These planar sensors can only be flexed along one axis, which makes them ideal for detections with flat-surface formats, but very difficult to use with devices that are designed to detect multiple axes of flex input.…”

“…Since input on the FlexStylus is also inherently analog, this research is somewhat more applicable to our work. Burstyn et al [7] used bend as a continuous input method for navigating stacked data using a flexible prototype.…”

Digital artists frequently use augmented styluses to modify parametric input such as stroke width. We contribute to this domain by creating a flexible stylus prototype, the FlexStylus, that detects deformation as a force vector with both an angle and an absolute value, providing two degrees of freedom for improving the experience of digital artists.We outline the construction of the prototype and the principles behind the sensing method, which uses a cluster of four fibre-optic flexion sensors. We propose interaction techniques using the FlexStylus to improve menu navigation and tool selection. Finally, we describe a study measuring accuracy during dynamic parameter adjustment. We compare users' ability to match a changing target value using a commercial pressure stylus and the FlexStylus' absolute deformation. When using the FlexStylus, users had a significantly higher accuracy overall. This suggests that deformation may be a useful input method for future work considering stylus augmentation.iii
