TL;DR: The relevant human vibrotactile perceptual capabilities are explained, the main types of commercial vib rotactile actuators are detailed, and how to build both monolithic and localized vibrotACTile displays are described.
Abstract: This paper reviews the technology and applications of vibrotactile display, an effective information transfer modality for the emerging area of haptic media. Our emphasis is on summarizing foundational knowledge in this area and providing implementation guidelines for application designers who do not yet have a background in haptics. Specifically, we explain the relevant human vibrotactile perceptual capabilities, detail the main types of commercial vibrotactile actuators, and describe how to build both monolithic and localized vibrotactile displays. We then identify exemplary vibrotactile display systems in application areas ranging from the presentation of physical object properties to broadcasting vibrotactile media content.

TL;DR: The technology behind creating artificial touch sensations and the relevant aspects of human touch are reviewed and the need to consider the neuroscience and perception behind the human sense of touch in the design and control of haptic devices is addressed.
Abstract: This article reviews the technology behind creating artificial touch sensations and the relevant aspects of human touch We focus on the design and control of haptic devices and discuss the best practices for generating distinct and effective touch sensations Artificial haptic sensations can present information to users, help them complete a task, augment or replace the other senses, and add immersiveness and realism to virtual interactions We examine these applications in the context of different haptic feedback modalities and the forms that haptic devices can take We discuss the prior work, limitations, and design considerations of each feedback modality and individual haptic technology We also address the need to consider the neuroscience and perception behind the human sense of touch in the design and control of haptic devices

TL;DR: ALVU (Array of Lidars and Vibrotactile Units), a contactless, intuitive, hands-free, and discreet wearable device that allows visually impaired users to detect low- and high-hanging obstacles, as well as physical boundaries in their immediate environment, is presented.
Abstract: This paper presents ALVU (Array of Lidars and Vibrotactile Units), a contactless, intuitive, hands-free, and discreet wearable device that allows visually impaired users to detect low- and high-hanging obstacles, as well as physical boundaries in their immediate environment. The solution allows for safe local navigation in both confined and open spaces by enabling the user to distinguish free space from obstacles. The device presented is composed of two parts: a sensor belt and a haptic strap. The sensor belt is an array of time-of-flight distance sensors worn around the front of a user’s waist, and the pulses of infrared light provide reliable and accurate measurements of the distances between the user and surrounding obstacles or surfaces. The haptic strap communicates the measured distances through an array of vibratory motors worn around the user’s upper abdomen, providing haptic feedback. The linear vibration motors are combined with a point-loaded pretensioned applicator to transmit isolated vibrations to the user. We validated the device’s capability in an extensive user study entailing 162 trials with 12 blind users. Users wearing the device successfully walked through hallways, avoided obstacles, and detected staircases.

TL;DR: In this article, the authors present the fundamentals and state of the art in haptic codec design for the Tactile Internet and discuss how limitations of the human haptic perception system can be exploited for efficient perceptual coding of kinesthetic and tactile information.
Abstract: The Tactile Internet will enable users to physically explore remote environments and to make their skills available across distances. An important technological aspect in this context is the acquisition, compression, transmission, and display of haptic information. In this paper, we present the fundamentals and state of the art in haptic codec design for the Tactile Internet. The discussion covers both kinesthetic data reduction and tactile signal compression approaches. We put a special focus on how limitations of the human haptic perception system can be exploited for efficient perceptual coding of kinesthetic and tactile information. Further aspects addressed in this paper are the multiplexing of audio and video with haptic information and the quality evaluation of haptic communication solutions. Finally, we describe the current status of the ongoing IEEE standardization activity P1918.1.1 which has the ambition to standardize the first set of codecs for kinesthetic and tactile information exchange across communication networks.

TL;DR: Two experiments establish links between desired knowledge about objects and hand movements during haptic object exploration, and establish that in free exploration, a procedure is generally used to acquire information about an object property, not because it is merely sufficient, butBecause it is optimal or even necessary.

TL;DR: Analysis of signals in tactile afferent neurons and central processes in humans reveals how contact events are encoded and used to monitor and update task performance.
Abstract: During object manipulation tasks, the brain selects and implements action-phase controllers that use sensory predictions and afferent signals to tailor motor output to the physical properties of the objects involved. Analysis of signals in tactile afferent neurons and central processes in humans reveals how contact events are encoded and used to monitor and update task performance.

TL;DR: Goldstein's SENSATION AND PERCEPTION as mentioned in this paper is a comprehensive examination of sensation and perception, with a balanced coverage of all senses, which offers an integrated examination of how the senses work together, and shows how seemingly simple experiences are actually extremely complex mechanisms and examines both psychophysical and physiological underpinnings of perception.
Abstract: Long regarded as the gold standard in sensation and perception texts, E. Bruce Goldstein's SENSATION AND PERCEPTION has helped more than 100,000 students make the connection between perception and physiology. Goldstein has crafted an easier-to-understand, and more student-friendly book, without sacrificing the text's comprehensive examination of sensation and perception. Goldstein takes readers on an intriguing journey through their senses, and chronicles scientists' efforts to understand the fascinating behind the scenes activity that allows us to perceive. With balanced coverage of all senses, this book offers an integrated examination of how the senses work together. Goldstein shows readers how seemingly simple experiences are actually extremely complex mechanisms and examines both the psychophysical and physiological underpinnings of perception. All material is presented in a way students find interesting and easy to follow. The book's visually dynamic presentation includes numerous color plates that are presented as visual topic essays. In addition, more than 50 hands-on demonstrations illustrate perceptual experiences. All are simple enough for students to do and are seamlessly integrated into the flow of the text.
