The Shape of Things to Come: Pin-Based Tactile Shape Displays
نویسنده
چکیده
Tactile displays are used to convey small-scale pressure and shape information to the finger tip. Our device designs include a 1x10 pin display using shape-memory alloy actuators and a 6x6 pin display using inexpensive commercially available servomotor-gearhead packages. Our human factors studies suggest that bandwidths of about 30 Hz are required for free exploratory motions with pin-based displays, and that perception and task performance can be assisted through signal processing algorithms that compensate for the artificial interactions between the display and finger tip. One promising application area is surgery, where relaying tactile information to the surgeon’s finger tip from within the patient’s body may enhance minimally invasive procedures.

A Tactile Shape Display Using RC Servomotors
Tactile displays are used to convey small-scale force and shape information to the tip of the finger. In this paper, we present a 6x6 tactile shape display that uses commercial RC servomotors to actuate an array of mechanical pins. The display has a maximum pin deflection of 2 mm along with a resolution of 4 bits. Pin spacing is 2 mm with a pin diameter of 1 mm. The display can accurately repre...

Tactile displays are used to convey small-scale force and shape information to the fingertip. We describe a 6 x 6 tactile shape display design that is low in cost and easily constructed. It uses commercially available RC servomotors to actuate an array of mechanical pins. The pins deflect a maximum of 2 mm, with a resolution of 0.1 mm. The pin center spacing is 2 mm and the pin diameter is 1 mm...

A shape optimization problem of cooling fins for computer parts and integrated circuits is modeled and solved in this paper. The main purpose is to determine the shape of a two-dimensional pin fin, which leads to the maximum amount of removed heat. To do this, the shape optimization problem is defined as maximizing the norm of the Nusselt number distribution at the boundary of the pin fin's con...

This paper describes the design of a controller for a tactile shape display for dexterous telemanipulation applications. This device consists of an array of pin elements which rest against the human finger tip. Shape memory alloy (SMA) wire actuators raise individual pins to approximate the desired surface shape on the skin. To overcome the slow response times of SMA actuators we have implement...
