“…When using less tactors, ERP overlap effects could cause a decrease in performance for short on- and off-times. On the other hand, stimuli delivered by few evenly spaced tactors are less vulnerable to spatio-temporal interactions compared to many tactors (Kirman, 1974b). …”

In this study, we investigated a Brain-Computer Interface (BCI) based on EEG responses to vibro-tactile stimuli around the waist. P300 BCIs based on tactile stimuli have the advantage of not taxing the visual or auditory system and of being potentially unnoticeable to other people. A tactile BCI could be especially suitable for patients whose vision or eye movements are impaired. In Experiment 1, we investigated its feasibility and the effect of the number of equally spaced tactors. Whereas a large number of tactors is expected to enhance the P300 amplitude since the target will be less frequent, it could also negatively affect the P300 since it will be difficult to identify the target when tactor density increases. Participants were asked to attend to the vibrations of a target tactor, embedded within a stream of distracters. The number of tactors was two, four or six. We demonstrated the feasibility of a tactile P300 BCI. We did not find a difference in SWLDA classification performance between the different numbers of tactors. In a second set of experiments we reduced the stimulus onset asynchrony (SOA) by shortening the on- and/or off-time of the tactors. The SOA for an optimum performance as measured in our experiments turned out to be close to conventional SOAs of visual P300 BCIs.

“…Numerous investigations into spatiotemporal tactile illusions [306] similar to the work by Hulin [256] have been conducted under names such as 'tactual movement' [72], 'apparent haptic movement' [455,456], and 'tactile apparent movement' [290,291]. What is generally observed is that participants will experience a series of discrete taps or vibrations in adjacent actuators, as a single stimulus moving over the skin [306].…”

“…On the other hand, the illusion of apparent motion is a phenomenon felt to be a single stimulus phenomenon similar to continuous motion between two points when the appropriate time difference between one stimulus presentation and another stimulus presentation exists when a contact stimulus is applied continuously to two points on the body. In prior research about phantom sensation and apparent movement, in tactile sensation, the frequency characteristics of apparent movements, the array characteristics of phantom sensation images, and the basic characteristics of the phenomena have been investigated [8][9][10][11][12][13]. In particular, with respect to phantom sensation involving three points using three contact stimulus elements, there are reports involving mechanical vibration stimulation, reports on the details of arrangement-specific or position-specific characteristics in phantom sensation images using electric pulse stimuli, and analysis from the perspective of the amount of information transmitted [14,15].…”

SUMMARYWhen two and more stimuli are arranged in the space, an illusion such as phantom sensation and apparent movement appear in the sense of touch. The foundation research to build a system for presenting two-dimensional information by using phantom sensation and apparent movement is done in this research. When apparent movement is used, information in the direction can be expressed between two elements of tactile stimulus in two-dimensional vector information. In this report, the authors propose the technique of information expression using three elements for tactile stimulus that the apparent movement is used with the phantom sensation together. By this technique, two-dimensional vector information can be expressed by three elements of tactile stimulus.
