TL;DR: The theory of signal detection has been studied extensively in the literature, see as mentioned in this paper for an overview. But the application of TSD is limited to the measurement of sensory attributes and discrimination scales.
Abstract: Contents: Preface. Psychophysical Measurement of Thresholds: Differential Sensitivity. Psychophysical Measurement of Thresholds: Absolute Sensitivity. The Classical Psychophysical Methods. Classical Psychophysical Theory. The Theory of Signal Detection. Further Considerations of TSD. Procedures of TSD. Some Applications of TSD. The Measurement of Sensory Attributes and Discrimination Scales. Partition Scales. Psychophysical Ration Scaling. Evaluation of Ratio Scaling Methods. The Psychophysical Law. Some Fundamental Issues in Psychophysical Scaling.

TL;DR: The proposed technology is based on the electrovibration principle, does not use any moving parts and provides a wide range of tactile feedback sensations to fingers moving across a touch surface, which enables the design of a wide variety of interfaces that allow the user to feel virtual elements through touch.
Abstract: We present a new technology for enhancing touch interfaces with tactile feedback. The proposed technology is based on the electrovibration principle, does not use any moving parts and provides a wide range of tactile feedback sensations to fingers moving across a touch surface. When combined with an interactive display and touch input, it enables the design of a wide variety of interfaces that allow the user to feel virtual elements through touch. We present the principles of operation and an implementation of the technology. We also report the results of three controlled psychophysical experiments and a subjective user evaluation that describe and characterize users' perception of this technology. We conclude with an exploration of the design space of tactile touch screens using two comparable setups, one based on electrovibration and another on mechanical vibrotactile actuation.

08 Dec 2009TL;DR: In psychophysics: A Practical Introduction, Second Edition, this article, the authors provide an introduction to the techniques for researching and understanding how the brain translates the external physical world to the internal world of sensation.
Abstract: Psychophysics: A Practical Introduction, Second Edition, is the primary scientific tool for understanding how the physical world of colors, sounds, odors, movements, and shapes translates into the sensory world of sight, hearing, touch, taste, and smell; in other words, how matter translates into mind. This timely revision provides a unique introduction to the techniques for researching and understanding how the brain translates the external physical world to the internal world of sensation. The revision expands and refines coverage of the basic tools of psychophysics research and better integrates the theory with the supporting software. The new edition continues to be the only book to combine, in a single volume, the principles underlying the science of psychophysical measurement and the practical tools necessary to analyze data from psychophysical experiments. The book, written in a tutorial style, will appeal to new researchers as well as to seasoned veterans. This introduction to psychophysics research methods will be of interest to students, scholars and researchers within sensory neuroscience, vision research, behavioral neuroscience, and the cognitive sciences. * Presents a large variety of analytical methods explained for the non-expert* Provides a novel classification scheme for psychophysics experiments * Includes a new software package for collecting and analyzing psychophysical data * Disseminates the pros and cons of different psychophysical procedures * Contains practical tips for designing psychophysical experiments

TL;DR: In this paper, the authors describe a new form of tactile output, called tactile icons, which can be used to communicate messages non-visually, and describe the parameters used to construct them and some possible ways to design them.
Abstract: 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.
