The Study of Bending and Twisting Input Modalities in Deformable Interfaces

Abstract

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.

“…(2) Human-computer interaction: Based on the results of the users' spatial controllability, Wu et al [6] proposed two interaction techniques (non-visual selection and a spatial gesture recognition technique for surgery) and four spatial partitioning strategies for human-computer interaction designers, which can improve the users' spatial controllability. To facilitate further developments in flexible display interactive technology, Yin et al [7] introduced a FlexSheet that can simulate the deformation environment. (3) Sensor: Han et al [8] presented a wearable PFC oxygen saturation measurement system using dual-wavelength, functional, near-infrared spectroscopy.…”
