“…From the data gathered from this range of time offsets, the offset for each actuator pair determined to create peak interference can be combined and used to trigger all the actuators in relation to the top left actuator. Our previous work with curved surfaces has shown that a near maximum peak may be produced with this method without the time consumption of going through every offset combination required if we were to scan through all four offsets simultaneously [36].…”

High-fidelity localized feedback has the potential of providing new and unique levels of interaction with a given device. Achieving this in a cost-effective reproducible manner has been a challenge in modern technology. Past experiments have shown that by using the principles of constructive wave interference introduced by time offsets it is possible to achieve a position of increased vibration displacement at any given location. As new interface form factors increasingly incorporate curved surfaces, we now show that these same techniques can successfully be applied and mechanically coupled with a universal actuation plate.

“…We would like to further explore the offset actuation technique implemented in objects with more pronounced curvature, such as that of a sphere [36]. A curved surface introduces points of localization that are both normal and tangential to the actuator.…”

“…The use of haptic environments with educative purposes has notably increased within the last two decades, especially for teaching abstract or complex concepts-from scenarios aimed to master basic science concepts [17] to secondary schools combining haptic interfaces and virtual reality applications for educational pur-poses [18]. Overall, the experience shows that haptic technology improves the level of human perception due to the deeper immersion it provides [19,20].…”

VIS-HAPT: A Methodology Proposal to Develop Visuo-Haptic Environments in Education 4.0

et al. 2021

Education 4.0 demands a flexible combination of digital literacy, critical thinking, and problem-solving in educational settings linked to real-world scenarios. Haptic technology incorporates the sense of touch into a visual simulator to enrich the user’s sensory experience, thus supporting a meaningful learning process. After developing several visuo-haptic simulators, our team identified serious difficulties and important challenges to achieve successful learning environments within the framework of Education 4.0. This paper presents the VIS-HAPT methodology for developing realistic visuo-haptic scenarios to promote the learning of science and physics concepts for engineering students. This methodology consists of four stages that integrate different aspects and processes leading to meaningful learning experiences for students. The different processes that must be carried out through the different stages, the difficulties to overcome and recommendations on how to face them are all described herein. The results are encouraging since a significant decrease (of approximately 40%) in the development and implementation times was obtained as compared with previous efforts. The quality of the visuo-haptic environments was also enhanced. Student perceptions of the benefits of using visuo-haptic simulators to enhance their understanding of physics concepts also improved after using the proposed methodology. The incorporation of haptic technologies in higher education settings will certainly foster better student performance in subsequent real environments related to Industry 4.0
