“…Tactile perception, similar to visual and auditory perception, provides us with a set of important information about an object of an interest (Shimojo et al 1999). For example, the pressure applied by the object on our skin provides us with shape information while the skin vibrations perceived when scanning the surface of the object mediates our recognition of the fine texture (Asamura et al 1998). Therefore, a tactile display that is capable of delivering both pressure and vibration information would greatly enhance our tactile perception of an object.…”

User study results showed that the fabricated multimodal tactile display system successfully delivered both shape information with an accuracy of 73 % and texture information with an accuracy of 90 %. This work demonstrates the potential of our multimodal tactile display system for uses in various applications such as tele-operation, tactile communication, and visual presentation for visually impaired.

“…This is the case in aids for the handicapped and in virtual reality, where spatial form, edges and texture can be important components of the information transferred through the skin (AsAMURA et al, 1998). A problem common to all tactile arrays is power consumption, as they are composed of several dozen transducers (CHOLEWIAK and WOLLOWlTZ, 1992;SAUNDERS, 1983).…”

“…HUMAN-MACHINE information transfer through tactile excitation has addressed new applications in virtual reality, robotics, telesurgery, sensory substitution and rehabilitation for the handicapped in the past few years (ASAMURA et al, 1998;HOWE et al, 1995;IKEY et al, 1997;ROSEN et al, 1999). Tactile interfaces permit a distant transfer of pressure, force or texture sensation, allowing a human to perform remote control of devices with improved precision.…”

“…in virtual reality, there is a need for physical interaction between the user and the computer to enhance the feeling of reality of the synthetic space in which the user is immersed. Haptic sensation has been proposed to complement visual image displays and auditory displays (IKEY et al, 1997;ASAMURA et al, 1998). Gloves have been developed to allow human interaction with virtual environments created by a computer (MACPHERSON and KEPPELL, 1998).…”

“…When the subject explores the surface of the virtual object, tactile displays apply forces on the hand or fingers (WALAIRACHT et al, 2000). Also, an application to identify textures was developed using tactile feedback (ASAMURA et al, 1998). Using cameras, visual information was transformed into tactile information and applied to the distal portion of the finger to simulate virtual touch on objects (OWAKI et al, 1999).…”

Human-machine information transfer through tactile excitation has addressed new applications in virtual reality, robotics, telesurgery, sensory substitution and rehabilitation for the handicapped in the past few years. Power consumption is an important factor in the design of vibrotactile displays, because it affects energy needs and the size, weight, heat dissipation and cost of the associated electronics. An experimental study is presented on the power required to reach tactile thresholds in electromechanical and piezo-electric transducers. Three different waveforms are considered, with an excitatory period formed by a burst of rectangular 50% duty cycle pulses (R50), rectangular low duty cycle pulses (RLO) and sinusoidal pulses (SIN). Ten different pulse repetition periods (RPs) were considered in the range 1/550-1/25 s. The voltage and current waveforms applied to the transducers at sensation thresholds in a group of 12 healthy subjects were sampled and stored in a digital oscilloscope. The average power was determined for each subject, and differences of two orders of magnitude were measured between the electromechanical and the piezo-electric transducer power consumption. Results show that, for the electromechanical transducer, a smaller power consumption of 25 microW was determined for RP = 1/25 s and the RLO waveform. In the case of the piezo-electric transducer, power of 0.21 microW was determined for SIN excitation and RP = 1/250 s. These results show the advantages of reducing power requirements for vibrotactile displays, which can be optimised by the choice of appropriate types of transducer, excitatory waveforms and pulse repetition periods.

Tactile stimulators manipulate sensors in the skin to produce sensations such as light touch, vibration, pressure, shape, and texture. The wide variety of applications for tactile stimulation include sensory substitution and augmentation, telepresence and telerobotic sensory feedback, improved immersion in virtual environments, and general information communication through the skin senses. This article discusses the three primary classes of tactile stimulation technologies: vibrotaction, dynamic mechanical shape arrays, and electrocutaneous stimulation. An overview of basic mechanoreceptor physiology is provided, including implications for stimulator design parameters. Predictions for the future development of tactile stimulation are presented, including the emerging applications in wearable computers.
