Vibrotactile Detection, Identification and Directional Perception of signal-Processed Sounds from Environmental Events: A Pilot Field Evaluation in Five Cases
Objectives: Conducting field tests of a vibrotactile aid for deaf/deafblind persons for detection, identification and directional perception of environmental sounds. Methods: Five deaf (3F/2M, 22–36 years) individuals tested the aid separately in a home environment (kitchen) and in a traffic environment. Their eyes were blindfolded and they wore a headband and holding a vibrator for sound id...
متن کاملA New Vision-Based and GPS-Signal-Independent Approach in Jamming Detection and UAV Absolute Positioning Assessment
The Unmanned Aerial Vehicles (UAV) positioning in the outdoor environment is usually done by the Global Positioning System (GPS). Due to the low power of the GPS signal at the earth surface, its performance disrupted in the contaminated environments with the jamming attacks. The UAV positioning and its accuracy using GPS will be degraded in the jamming attacks. A positioning error about tens of...
متن کاملWithin, but not between hands interactions in vibrotactile detection thresholds reflect somatosensory receptive field organization
Detection of a tactile stimulus on one finger is impaired when a concurrent stimulus (masker) is presented on an additional finger of the same or the opposite hand. This phenomenon is known to be finger-specific at the within-hand level. However, whether this specificity is also maintained at the between hand level is not known. In four experiments, we addressed this issue by combining a Bayesi...
متن کاملEffects of sexual arousal on vibrotactile detection thresholds in aged men with and without erectile dysfunction.
BACKGROUND Erectile dysfunction (ED) is a common problem in ageing men. Abnormalities in sexual arousal may contribute to its development, and to the failure of pharmacological therapies. However, there are few objective ways of assessing arousal. Sexual arousal has been shown to affect vibrotactile detection thresholds (VDT) in young, healthy men. The present study assessed the effects of sexu...
متن کاملMeasurements of vibrotactile perception thresholds at the fingertips in Poland.
OBJECTIVES The measurement of vibrotactile perception thresholds (VPTs) at fingertips in workers belongs in Poland among obligatory methods used to diagnose hand-arm vibration syndrome. The aim of the study was to compare vibrotactile perception threshold (VPT) values for healthy subjects using two different types of measuring equipment, i.e. a system designed according to the requirements of t...
