Touch, Texture and Haptic Feedback: A Review on How We Feel the World around Us

Abstract

Touch is one most of the important aspects of human life. Nearly all interactions, when broken down, involve touch in one form or another. Recent advances in technology, particularly in the field of virtual reality, have led to increasing interest in the research of haptics. However, accurately capturing touch is still one of most difficult engineering challenges currently being faced. Recent advances in technology such as those found in microcontrollers which allow the creation of smaller sensors and feedback devices may provide the solution. Beyond capturing and measuring touch, replicating touch is also another unique challenge due to the complexity and sensitivity of the human skin. The development of flexible, soft-wearable devices, however, has allowed for the creating of feedback systems that conform to the human form factor with minimal loss of accuracy, thus presenting possible solutions and opportunities. Thus, in this review, the researchers aim to showcase the technologies currently being used in haptic feedback, and their strengths and limitations.

Application and Design of Virtual Reality-Based Interactive Film System in Presentation of Architectural Design

“…Kinesthetic feedback: Force feedback system is ideal for kinesthetic feedback because it is most suitable for generating directional forces. The two types of systems for kinesthetic feedback in the current market are grounded and exoskeleton-based devices [15]. We have adopted exoskeletonbased devices because it allows the user to move around the space freely, and it is also more convenient.…”

VIBES: Vibro-Inertial Bionic Enhancement System in a Prosthetic Socket

“…1). The mechanical part comprises a battery pack (6), an electronic board (7) and two IMUs (8). Two planar vibrotactile actuators ( 4) are integrated into the inner socket and part of the feedback interface.…”

“…The electrotactile electrodes are lightweight and can be easily integrated into the prosthesis. However, they can elicit unnatural sensations often considered unpleasant, high electrical voltage is required, and the presence of electrical fields can interfere with the myoelectric measurements necessary for prosthesis control [5], [6].…”

A helping hand: roles for accessory cells in the sense of touch across species

“…In addition, since the advent of virtual reality (VR), a further understanding of the basic science of touch is needed to reproduce the perception of being in another location. However, at present, adding touch to visualonly interfaces remains a crucial impediment to the VR industry (See et al, 2022).…”
