Tactons: structured tactile messages for non-visual information display
Tactile displays are now becoming available in a form that can be easily used in a user interface. This paper describes a new form of tactile output. Tactons, or tactile icons, are structured, abstract messages that can be used to communicate messages non-visually. A range of different parameters can be used for Tacton construction including: frequency, amplitude and duration of a tactile pulse, plus other parameters such as rhythm and location. Tactons have the potential to improve interaction in a range of different areas, particularly where the visual display is overloaded, limited in size or not available, such as interfaces for blind people or in mobile and wearable devices. This paper describes Tactons, the parameters used to construct them and some possible ways to design them. Examples of where Tactons might prove useful in user interfaces are given
An Empirical Evaluation On Vibrotactile Feedback For Wristband System
With the rapid development of mobile computing, wearable wrist-worn is
becoming more and more popular. But the current vibrotactile feedback patterns
of most wrist-worn devices are too simple to enable effective interaction in
nonvisual scenarios. In this paper, we propose the wristband system with four
vibrating motors placed in different positions in the wristband, providing
multiple vibration patterns to transmit multi-semantic information for users in
eyes-free scenarios. However, we just applied five vibrotactile patterns in
experiments (positional up and down, horizontal diagonal, clockwise circular,
and total vibration) after contrastive analyzing nine patterns in a pilot
experiment. The two experiments with the same 12 participants perform the same
experimental process in lab and outdoors. According to the experimental
results, users can effectively distinguish the five patterns both in lab and
outside, with approximately 90% accuracy (except clockwise circular vibration
of outside experiment), proving these five vibration patterns can be used to
output multi-semantic information. The system can be applied to eyes-free
interaction scenarios for wrist-worn devices.Comment: 10 pages
Non-visual information display using tactons
This paper describes a novel form of display using tactile output. Tactons, or tactile icons, are structured tactile messages that can be used to communicate message to users non visually. A range of different parameters can be used to construct Tactons, e.g.: frequency, amplitude, waveform and duration of a tactile pulse, plus body location. Tactons have the potential to improve interaction in a range of different areas, particularly where the visual display is overloaded, limited in size or not available, such as interfaces for blind people or on mobile and wearable devices
I see where this is going: a psychophysical study of directional mid-air haptics and apparent tactile motion
Mid-air haptic technology can render a plethora of tactile sensations including points, lines, shapes, and textures. To do so, one requires increasingly complex haptic displays. Meanwhile, tactile illusions have had widespread success in the development of contact and wearable haptic displays. In this paper, we exploit the apparent tactile motion illusion to display mid-air haptic directional lines; a prerequisite for the rendering of shapes and icons. We present two pilot studies and a psychophysical study that contrasts a dynamic tactile pointer (DTP) to an apparent tactile pointer (ATP) in terms of direction recognition. To that end, we identify optimal duration and direction parameters for both DTP and ATP mid-air haptic lines and discuss the implications of our findings with respect to haptic feedback design, and device complexity
Wearable performance
This is the post-print version of the article. The official published version can be accessed from the link below - Copyright @ 2009 Taylor & FrancisWearable computing devices worn on the body provide the potential for digital interaction in the world. A new stage of computing technology at the beginning of the 21st Century links the personal and the pervasive through mobile wearables. The convergence between the miniaturisation of microchips (nanotechnology), intelligent textile or interfacial materials production, advances in biotechnology and the growth of wireless, ubiquitous computing emphasises not only mobility but integration into clothing or the human body. In artistic contexts one expects such integrated wearable devices to have the two-way function of interface instruments (e.g. sensor data acquisition and exchange) worn for particular purposes, either for communication with the environment or various aesthetic and compositional expressions. 'Wearable performance' briefly surveys the context for wearables in the performance arts and distinguishes display and performative/interfacial garments. It then focuses on the authors' experiments with 'design in motion' and digital performance, examining prototyping at the DAP-Lab which involves transdisciplinary convergences between fashion and dance, interactive system architecture, electronic textiles, wearable technologies and digital animation. The concept of an 'evolving' garment design that is materialised (mobilised) in live performance between partners originates from DAP Lab's work with telepresence and distributed media addressing the 'connective tissues' and 'wearabilities' of projected bodies through a study of shared embodiment and perception/proprioception in the wearer (tactile sensory processing). Such notions of wearability are applied both to the immediate sensory processing on the performer's body and to the processing of the responsive, animate environment.

Prevalence of haptic feedback in robot-mediated surgery : a systematic review of literature
© 2017 Springer-Verlag. This is a post-peer-review, pre-copyedit version of an article published in Journal of Robotic Surgery. The final authenticated version is available online at: https://doi.org/10.1007/s11701-017-0763-4With the successful uptake and inclusion of robotic systems in minimally invasive surgery and with the increasing application of robotic surgery (RS) in numerous surgical specialities worldwide, there is now a need to develop and enhance the technology further. One such improvement is the implementation and amalgamation of haptic feedback technology into RS which will permit the operating surgeon on the console to receive haptic information on the type of tissue being operated on. The main advantage of using this is to allow the operating surgeon to feel and control the amount of force applied to different tissues during surgery thus minimising the risk of tissue damage due to both the direct and indirect effects of excessive tissue force or tension being applied during RS. We performed a two-rater systematic review to identify the latest developments and potential avenues of improving technology in the application and implementation of haptic feedback technology to the operating surgeon on the console during RS. This review provides a summary of technological enhancements in RS, considering different stages of work, from proof of concept to cadaver tissue testing, surgery in animals, and finally real implementation in surgical practice. We identify that at the time of this review, while there is a unanimous agreement regarding need for haptic and tactile feedback, there are no solutions or products available that address this need. There is a scope and need for new developments in haptic augmentation for robot-mediated surgery with the aim of improving patient care and robotic surgical technology further.Peer reviewe
Personalising Vibrotactile Displays through Perceptual Sensitivity Adjustment
Haptic displays are commonly limited to transmitting a discrete
set of tactile motives. In this paper, we explore the
transmission of real-valued information through vibrotactile
displays. We simulate spatial continuity with three perceptual
models commonly used to create phantom sensations: the linear,
logarithmic and power model. We show that these generic
models lead to limited decoding precision, and propose a
method for model personalization adjusting to idiosyncratic
and spatial variations in perceptual sensitivity. We evaluate
this approach using two haptic display layouts: circular, worn
around the wrist and the upper arm, and straight, worn along
the forearm. Results of a user study measuring continuous
value decoding precision show that users were able to decode
continuous values with relatively high accuracy (4.4% mean
error), circular layouts performed particularly well, and personalisation
through sensitivity adjustment increased decoding
precision
