“…In addition to taking the deformation degree of the equipment directly as the input parameter [5,7,17], many researchers have also discussed the input potential of the combination of deformation and other input methods, such as pressure [24,25], touch [26,27], and even provide new interaction methods for people with visual impairment by combining hearing [28] and kinesthetic [27].…”

The deformable input provides users with the ability of physical operation equipment to interact with the system. In order to facilitate further development in flexible display interactive technology, we devised FlexSheet, an input device that can simulate the deformation environment. This paper presents two forms of deformation input, bending and twisting, with regard to three selection techniques. We conduct a controlled experiment to select discrete targets by combining two input forms and three selection strategies, taking into account the influence of visual feedback. Further, we use the deformation angle to reflect the degree of deformation and map it to the experimental variables. In accordance with the experimental results, we analyze the experimental performance under three evaluation indexes and prove the viability of our selection technology in bending and twisting input modes. Finally, we provide suggestions on the control level in bending and twisting input modes, respectively.

A simple, highly efficient and low cost roll-to-roll (R2R) UV imprinting lithography facility was achieved for fabricating micro-structures. Firstly, a novel microlens array with focuses distributed on a curved surface was designed and analyzed by an optical software ZEMAX. Then an ultra-precision diamond machine was applied to generate the freeform microlens array features on the master mold, and a belt-type polydimethylsiloxane (PDMS) mold with a microlens array pattern was prepared from the machined master mold. The R2R process was employed to replicate the microlens arrays, followed by an evaluation of their profiles and optical properties. Our experiments demonstrate that the applied method is reliable and efficient for producing the polymeric microlens arrays.

Light‐field head‐mounted displays reduce the visual effort: A user study

et al. 2022

Head‐mounted displays (HMDs) allow the visualization of virtual content and the change of view perspectives in a virtual reality (VR). Besides entertainment purposes, such displays also find application in augmented reality, VR training, or tele‐robotic systems. The quality of visual feedback plays a key role for the interaction performance in such setups. In the last years, high‐end computers and displays led to the reduction of simulator sickness regarding nausea symptoms, while new visualization technologies are required to further reduce oculomotor and disorientation symptoms. The so‐called vergence–accommodation conflict (VAC) in standard stereoscopic displays prevents intense use of 3D displays, so far. The VAC describes the visual mismatch between the projected stereoscopic 3D image and the optical distance to the HMD screen. This conflict can be solved by using displays with correct focal distance. The light‐field HMD of this study provides a close‐to‐continuous depth and high image resolution enabling a highly natural visualization. This paper presents the first user‐study on the visual comfort of light‐field displays with a close‐to‐market HMD based on complex interaction tasks. The results provide first evidence that the light‐field technology brings clear benefits to the user in terms of physical use comfort, workload, and depth matching performance.
