Investigation of Vhi Affected by the Density of Mechanoreceptive Units for Virtual Sensation

چکیده
The velvet hand illusion (VHI) is an innovative tactile illusion that enables a human to perceive a velvety sensation by gently rubbing the hands on both sides of wire mesh string through a frame. In order to enhance tactile displays presentation ability, VHI’s mechanism is applied through a series of psychophysical experiments. In this paper, we have investigated the effects of several physical parameters on intensity variation of VHI in subjects’ fingers and fingertips, such as wire distance D and a dimensionless ratio of wire stroke r to wire distance r/D in passive touch based on psychophysical experiment. We obtain D = 45 mm and r/D ≈ 1 as optimum values for VHI intensity for wire distance INTERNATIONAL JOURNAL ON SMART SENSING AND INTELLIGENT SYSTEMS VOL. 6, NO. 4, SEPTEMBER 2013

Investigation on Velvet Hand Illusion Using Psychophysics and Fem Analysis
In the velvet hand illusion (VHI), a person rubs his/her hands together on either side of wires strung through a frame, producing the sensation of rubbing a very smooth and soft surface like velvet. We investigate the VHI mechanism to obtain an effective hint for a new tactile display because such tactile illusions play a good role in deceiving the brain so that operators believe that a virtual...

متن کاملMeasurement of Tactile Sensation by Vibrometric Technique
The ability to quantify the sensation of vibration is a valuable indicator of the state of tactile sensory system. Elevated threshold in the detection of vibratory stimuli may be the first sign of neuropathological disorders. Mechanoreceptive units are responsible for vibrotactile sensation of the skin, and different types of these units respond to different frequencies. Vibrometry is based on ...
متن کاملVelvety Massage Interface (VMI): Tactile Massage System Applied Velvet Hand Illusion
Velvet Hand Illusion (VHI) is a tactile illusion that generates sensation of soft and smooth feelings. We propose to apply this illusion to develop the novel interface called Velvety Massage Interface (VMI). This system gives realistic sensation of being massaged on surface of sole of foot like reflexology. We conducted an experiment to verify if the VHI is generated to the sole of foot and if ...
