“…We have discussed the reasons for this failure and some indications of discrimination learning. Haptic perception has always been an important topic in humans, for example, in the study of virtual reality (Kern et al, 2023;Tanaka & Kubota, 2022;Tanaka et al, 2023), but in comparative studies with nonhuman primates, it has been on the decline since the cross-modal perception studies of the 1960s to 1970s, with a few exceptions in neurophysiological studies. Nevertheless, we believe that the use of advanced technology, as demonstrated in this study, can pave the way for new research avenues in the field of tactile perception and cognition from a comparative cognitive perspective.…”

While force-feedback devices have been developed in areas such as virtual reality, there have been very few comparative cognitive studies in nonhuman animals using these devices. In addition, although cross-modal perception between vision and touch has been actively studied in nonhuman primates for several decades, there have been no studies of their active haptic perception. In this study, we attempted to train force discrimination in chimpanzees using a force-feedback device modified from a trackball. Chimpanzees were given different levels of force feedback (8.0 N vs. 0.5 N) when moving the on-screen cursor to the target area by manipulating the trackball and were required to select one of two choice stimuli based on the force cue. The experiment was conducted using a trial-block procedure in which the same force stimulus was presented for a fixed number of trials, and the force stimulus was changed between blocks. The block size was progressively reduced from 10 trials. Four chimpanzees were trained, but none reached the learning criterion (80% or more correct responses under the condition that the force stimuli were presented randomly). However, a detailed analysis of the chimpanzees' performance before and after the trial-block switching revealed that their choice behavior could not be explained by a simple win-stay/lose-shift strategy, suggesting that the switching of the force stimuli affected the chimpanzees' choice behavior. It was also found that the chimpanzees performed better when switching from small to large force stimuli than when switching from large to small force stimuli. Although none of the chimpanzees in this study acquired force discrimination, future studies using such force feedback devices will provide new insights for understanding haptic cognition in nonhuman primates from a comparative cognitive perspective.

“…In recent years, haptic perception has been actively studied in areas such as virtual reality, and devices for force feedback have been intensively developed (Burdea et al, 1996) and are being put into practical use (e.g., Kern et al, 2023).…”

“…Haptic interfaces refers to haptic devices, consisting of manipulator with sensors, actuators, or both, and the software-based computer control mechanisms. Typically, optimizing for one of the features comes at the expense of other features [12], [13]. Take, for example, the multiple degrees of freedom (DoF) feedback, which is the number of independent dimensions for controlling haptic feedback.…”

Origami, the art of paper folding, addresses traditionally conflicting requirements for designing both powerful and low-cost haptic interfaces. As of today, there are no comprehensive reviews that cover origami-inspired haptic actuation, sensing, design processes, and fabrication. To fill this void, this paper summarizes existing origami-inspired haptic technologies in terms of workspace, degrees of freedom (DoF), power consumption, control methods, sensing, and actuation. The paper also presents an iterative design process for pattern generation and origami-inspired haptic characterization. Using this design process, we demonstrate a case study that involves the design, development, and evaluation of a novel syringe haptic interface for dental simulation. Our main findings suggest that origami-inspired haptics need more mathematically optimized and versatile design, as well as novel materials that offer a room for embedded sensing and actuation.

El presente documento describe el desarrollo de un control para un sistema maestro-esclavo compuesto por un joystick físico con dos grados de libertad (sistema maestro) y su gemelo virtual (sistema esclavo). Se implementó un control robusto basado en modos deslizantes con la finalidad de que el joystick virtual realice el seguimiento de trayectoria proporcionada por el joystick maestro. El principal enfoque de este trabajo es la implementación de un algoritmo de control que considera restricciones de posición variantes en tiempo para asegurar que el dispositivo esclavo se mantenga en una zona de trabajo específica y así mejorar la interacción hombre-máquina. Se realizaron simulaciones para comprobar el funcionamiento del sistema, se comparó control propuesto con un control por modos deslizantes de primer orden. Acorde a los resultados obtenidos, se evidenció que cuando se implementa el esquema de control con restricciones propuesto se garantiza el cumplimiento de las restricciones.

Conclusion

Abstract: Like any other design process, the design of haptic systems is largely influenced by the optimization of a technical system, which is based on the consideration of a large number of decisions about individual components that usually influence each other.
