Tactile arrays use a matrix of individually controllable elements to present spatial and temporal patterns of cutaneous information. Early devices of this type were in the field of sensory substitution to replace vision or hearing for users with a sensory impairment. Many advances have been made due to the appropriation of tactile displays for telerobotics and virtual reality, to represent physical contact with a remote or simulated environment. However, many of these have been limited to engineering prototypes. The recent commercial availability of affordable, portable tactile pin arrays has provided renewed impetus to apply the technology to sensory substitution applications. Lack of access to digitally stored data can prove a significant barrier to blind people seeking careers in numerate disciplines. Tactile displays could potentially provide a discrete and portable means of accessing graphical information in an intuitive non-visual manner. Results are presented from experiments on tactual perception related to understanding graphs and simple visualisations with a commercially available tactile array device. It was found that subjects could discriminate positive or negative line gradient to within 74.71 of the horizontal, compared to 73.251 for results with a force feedback mouse and 72.421 with a raised paper representation. r

“…In some aspects, Digital Clay is similar to tactile sensors with tactile stimulators [1] [2] except Digital Clay has a longer stroke and operates hydraulically. Electromagnetic [3], pneumatic [4] and shape memory alloy [5] actuators have been used in tactile arrays. The sizes of these arrays are small, about the size of the pad of a finger.…”

Digital Clay is an NSF funded project for human machine communication through a tangible haptic surface actuated using fluid power. Digital Clay's hardware can be divided into three subsystems: massive-integrated actuator-sensor array, fluidic driving system, and control system. Focus of this paper is the control of some of the special mechanisms of Digital Clay. Specifically, the Fluid Matrix Drive, Capacitive-Coupled Resistive Sensing technology for position feedback and the other control related issues are discussed. Analysis and testing results on these topics are provided based on a 5x5 actuator array prototype. Most of the topics discussed in this paper are widely applicable to other devices as well as Digital Clay.

Abstract-Many surgical procedures are now performed using the techniques of minimally invasive surgery (MIS), in which unnecessary trauma is limited by reducing the size of incisions to less than about 1 cm or by using catheters or endoscopes threaded through vessels, the gastrointestinal tract, or other tubular structures. Micromechatronic technologies have great potential to allow access to regions now inaccessible, or to enhance the surgeon's abilities in applications where current minimally invasive techniques do not permit the full range of human dexterity and perception. Key needs and applications in MIS are identified, and relevant technologies, methods, and systems issues in mechatronics are discussed. The authors' millirobotic system for MIS of the abdomen is used as an example.
