“…We have shown that there is a perceptual tolerance for conflicting locations of visual and tactile touch, in which the two sensory modalities are fused into a single percept despite arising from different locations (Caballero and Rombokas, 2019). Furthermore, combining multiple modalities either in the form of augmenting otherwise passive haptic sensations (Choi et al, 2020), using pseudo-haptic illusions (Achibet et al, 2017;Samad et al, 2019), or a believable simulation (Kuchenbecker et al, 2006;Chan et al, 2021), can possibly mitigate the lack of congruence between the visual and tactile sensation. We therefore extend what Ando et al (2007) has proposed to immersive virtual reality by placing the haptic device on the fingernail and finger dorsum and compensating for the distant stimulation with believable visual and haptic rendering, which leaves the fingerpads still free to interact with real-world objects.…”

We introduce Haplets, a wearable, low-encumbrance, finger-worn, wireless haptic device that provides vibrotactile feedback for hand tracking applications in virtual and augmented reality. Haplets are small enough to fit on the back of the fingers and fingernails while leaving the fingertips free for interacting with real-world objects. Through robust physically-simulated hands and low-latency wireless communication, Haplets can render haptic feedback in the form of impacts and textures, and supplements the experience with pseudo-haptic illusions. When used in conjunction with handheld tools, such as a pen, Haplets provide haptic feedback for otherwise passive tools in virtual reality, such as for emulating friction and pressure-sensitivity. We present the design and engineering for the hardware for Haplets, as well as the software framework for haptic rendering. As an example use case, we present a user study in which Haplets are used to improve the line width accuracy of a pressure-sensitive pen in a virtual reality drawing task. We also demonstrate Haplets used during manipulation of objects and during a painting and sculpting scenario in virtual reality. Haplets, at the very least, can be used as a prototyping platform for haptic feedback in virtual reality.

“…To satisfy the improved presence of the user in immersive VR, visual satisfaction should be preceded. For this reason, interest is growing in multimodality studies [23,24] that consider visual and auditory senses or visual and tactile senses simultaneously, and studies on pseudo-haptics that combine visual experiences and haptic systems [25,26]. As such, various approaches have been made to enhance presence sensation in immersive VR.…”

Maze Terrain Authoring System in Immersive Virtual Reality for New Visual Realism

This paper proposes a maze terrain authoring system with which a user can automatically calculate various and complex maze patterns to compose maze terrains in an easier and more intuitive structure. Using the maze terrain information calculated by using the proposed authoring system, a 3D maze terrain is generated quickly and effectively, and through this, the user’s visual realism in an immersive virtual reality is increased to provide a new presence. The proposed maze terrain authoring system consists of three core functions: a function that automatically generates a grid maze of various sizes and patterns based on a maze generation algorithm; a function that calculates a circular maze in an intuitive structure; and a function that transforms a sketch-based maze by using an image-processing algorithm. Through the authoring system consisting of these functions, various maze terrains from uniform mazes to irregular mazes can be generated effectively. This study produces maze terrains of various concepts directly by using maze information calculated through the authoring system. In addition, through experiments, this study analyzes the efficiency in an immersive virtual reality and the presence through visual realism. In this process, the suitability of the authoring system is also analyzed in combination with a survey.

The aim of this work is to make known the possible applicability and usefulness of new technologies such as virtual reality and haptic devices to improve the education of children of pre-school age. The aim is not only to integrate these new technologies into pre-school education but also to evaluate the improvements that this would introduce, for which a system has been designed that includes a computer and a haptic device whose shape resembles a pencil and its use is very similar to a mouse. Several virtual interfaces have been designed in which different environments are presented where the child must perform tasks designated by the teacher; the child interacts with these interfaces with the help of the haptic device that also has the ability to feedback forces that will prevent the child from performing the task incorrectly. The interfaces are designed as games to please the child, for this 3D software is used, the haptic device is a Geomagic Touch and the tasks are structures by the teacher, according to the age and skill that is intended to improve in the child. The proposals and results of two previous works carried out by the authors are presented.
