Vibrotactile Guidance Cues For Target Identification
… of this dissertation was to establish how vibrotactile guidance cues can be used to improve marksmanship. This work originated in an effort to provide covert communication, navigation, and weapon aiming cues for infantrymen. It is predominantly an application-driven investigation rather …

ComTouch : a vibrotactile mobile communication device
… touch can be remotely represented by means of a vibrotactile, or touch-and-vibration, interface. Touch has potential to improve existing remote communication by allowing tactile cues to augment the audio-visual information in real-time. The approach of ComTouch is to use this vibrotactile mapping …

Vibrotactile sensory substitution for post-stroke rehabilitation
… of the hand, and also provides the appropriate vibrotactile feedback to another location on the body that might allow individuals to recover some sense of touch. The method was between 96% and 100% successful in providing the appropriate vibrotactile feedback for normal and large grip forces. …

Effects of Vibrotactile Display Position and Shape on Extrapersonal Localization
<p>Vibrotactile displays are capable of conveying extrapersonal spatial information to users navigating or operating within a three-dimensional environment (e.g., aircraft pilots). Although vibrotactile displays can be applied to many parts of the body, recent applications have focused on …

Vibrotactile pattern recognition on the torso : effects of concurrent activities
Vibrotactile displays have been created to aid vision or hearing through the sense of touch. These displays communicate with the user to provide information. The focus of this thesis was to determine how concurrent activity affects vibrotactile signal recognition. An overall accuracy recognition …

Mechanical and psychophysical studies of surface wave propagation during vibrotactile stimulation
Vibrotactile displays are based on mechanical stimulation delivered using an array of motors to communicate with the user. The way in which the display's motors are spaced and positioned on the body can have a significant impact on the effectiveness of communication, especially for tactile displays …

Vibrotactile pattern recognition on the torso with one and two dimensional displays
… experiments showed that identification of the vibrotactile patterns was slightly superior on the two-dimension tactile array on the torso as compared to the one-dimension tactile array around the waist.

Interactions between the auditory and vibrotactile senses : a study of perceptual effects
… and tactile stimuli. These experiments present vibrotactile stimuli to the fingertip and auditory tones diotically in broadband noise. Our hypothesis states that if the auditory and tactile systems integrate, the performance of the two sensory stimuli presented simultaneously will be different …

A vibrotactile display design for the feedback of external prosthesis sensory information to the amputee wearer
This thesis documents the development of a vibrotactile display to be incorporated into a powered ankle-foot prosthesis. Although existing devices have addressed the need for tactile and proprioceptive feedback in external prostheses, there has not yet been an attempt to develop and clinically …

The Effect of Interaction Method and Vibrotactile Feedback on User Experience and Performance in the VR Games
… whole-hand interaction using hand tracking) and vibrotactile feedback on user experience in the VR game. In Study 1 of this Thesis, I recruited 36 participants and compared the user's sense of presence, engagement, usability, and task performance under three different conditions: (1) VR …

Vibrational Feedback Training System for Use with SEMG Controlled Powered Prostheses
… forearm muscles, and experience visual and vibrotactile feedback relevant to the grasping force in the process. This can then be used to train potential wearers of real EMG controlled prostheses, with or without vibrotactile feedback. To test this system an experiment was designed and …

Self-Actuated Vibration Through Mechanofluidic Instabilities Using Soft Wearable Devices
… a widely used mode of haptic communication, as vibrotactile cues provide salient haptic notifications to users and are easily integrated into wearable or handheld devices. Fluidic textile-based devices offer an appealing platform for the incorporation of vibrotactile haptic feedback, as they can …

A tactile communication system for navigation
A vibrotactile display for use in navigation has been designed and evaluated. The arm and the torso, which offer relatively large and flat surface areas, were chosen as locations for the displays. The ability of subjects to identify patterns of vibrotactile stimulation on the arm and torso was …

Thermal effects upon human vibratory sensitivity
Vibrotactile sensitivity is measured using a "dry" procedure as opposed to a "wet" procedure previously used. Thresholds are determined using 40 Hz and 160 Hz stimuli across seven temperatures ranging from 20°C to 44°C. Twelve male subjects participated in each of four sessions, producing a high …

Haplós: Towards Technologies for and Applications of Somaesthetics
How can vibrotactile stimuli be used to create a technology-mediated somatic learning experience? This question motivates this practice-based research, which explores how the Feldenkrais Method and cognate neuroscience research can be applied to technology design. Supported by somaesthetic …
