Immersive technology, refers to various novel ways of creating and interacting with applications and experiences, e.g., virtual reality (VR), has been used in various simulations and training where preparing real/physical settings is not ideal or possible, or where the use of virtual contents is otherwise beneficial. Realizing realistic interactions with virtual content is crucial for a quality experience and the effectiveness of such simulation and training. In this paper, we propose a kinematics-based realistic hand interaction method to enable a physically plausible grip-lifting experience in VR. The method reflects three kinematic characteristics of the hand: the force at contact points, finger flexion, and the speed of hand/finger motion, and we developed a grip-lift interaction prototype using the proposed method. To examine the sense of realism and hand poses during the grip-lift interaction, we conducted a human subjects experiment using the prototype, resulting in positive effects on the perceived realism and usefulness of the interaction. Grip-lifting is a fundamental interaction technique that is involved in most embodied interaction scenarios. Our method would contribute to the design and development of realistic virtual experiences, of which we will discuss the implications and potential based on our findings.

“…This is illustrated in Figure 3. The forces are small in comparison to the thermal stress, and so do not significantly affect R from (9). Using volumes of revolution to calculate volumes with respect to Figure 3, and the condition V1 = V3, we get (16) with 𝛾 and β defined as 𝑅 cos(𝜃) and 𝑅 sin(𝜃) respectively.…”

“…APACITIVE tactile pressure sensors are a common method of measuring and quantifying tactile interactions, and are routinely employed in applications in contact with the human body [1], such as in medical imaging [2], [3], medical therapeutics [4]- [6], haptics and wearables [7], [8], and ergonomic testing [9] amongst others. These applications often involve large temperature variations and differentials during active operation, where performance is expected to be maintained throughout.…”

Capacitive tactile pressure sensors are increasingly used in ergonomic testing and medical devices, specifically for human body measurement and characterising human interactions with their environment, where temperature coefficients are important considerations. New wearable and flexible sensor designs appear regularly in the literature however they rarely discuss why respective designs are improvements over predecessors, or any sensor performance optimisations for their intended applications. This lack of clear design rationale in the literature leads to inefficient design iterations and suboptimal sensor performance as designs are seemingly 'trial and errored'. This work analytically models the steady state mechanics of a simple commercial-off-the-shelf capacitive tactile sensor, SingleTact™ S15-4.5N, with nominal base temperature sensitivity of 0.2% FSR/°C, using multi-objective optimisation on the critical factors to minimise the temperature coefficient. This work investigates the governing factors for the temperature coefficients via sensitivity analysis on the experimentally validated model, providing novel design insight. By optimizing the design parameters within practical bounds, improvements of 16.16%, 16.47%, and 14.74%, can be achieved for the baseline, sensitivity, and linearity (steady state) temperature coefficients respectively. The model is shown to be useful in determining dominant factors controlling the steady state temperature coefficients as well as estimating sensitivity to manufacturing tolerances. This approach will be used on more complex designs in future to ensure optimal application performance, and assess the impact of manufacturing constraints on sensor performance to the benefit of manufacturers and end users alike.
