We present a new tactile display for use in dexterous telemanipulation and virtual reality. Our system renders the location of the contact centroid moving on the user’s fingertip. Constructed in a thimble-sized package and mounted on a haptic force-feedback device, it provides the user with concurrent feedback of contact location and interaction forces.We believe such a design will enable more ...

ACR/NEMA (now DICOM) has released for public comment the Display Function Standard document. This standard, produced by ACR/NEMA Working Group XI, has been developed in order to solve the problem of standardizing the response of grey scale display systems . This paper presents a methodology proposed in the Display Function Standard for quantitatively calculating the conformance of a display dev...

A surface meso-structure measurement and tactile device input vibration signal synthesis techniques are proposed. To measure the surface meso-structure, some photos are taken using a fixed camera with changing lighting incidence direction. A surface normal image is obtained from these photos. Then vibration signal as tactile device input signal is synthesized. Adding friction sound, the tactile...

Flexible display devices allow users to interact with the device by deforming the surface of the display to trigger a command. When these devices become mainstream, for example as smart phones, e-readers, or tablets, they will require a means of authenticating legitimate users. In this poster, we present an authentication scheme for flexible display devices, its implementation on a flexible dis...

Existing large scale display systems generally adopt an indirect approach to user interaction. This is due to the use of standard desktop-oriented devices, such as a mouse on a desk, to control the large wall-sized display. By using an infrared laser pointer and an infrared tracking device, a more direct interaction with the large display can be achieved, thereby reducing the cognitive load of ...

Beam projector is popularly used for presentation. In order to pay attention to local area of the beam projector display, a laser pointer is used together with a pointing device(Mouse). Simple wireless presenter has limited functions of a pointing device such as “go to next slide” or “back to previous slide” in a specific application(Microsoft PowerPoint) through wireless channel; thus, there i...

We propose a tentative tactile perception model called Simple Bundle Model and examine it by a tactile display based on ultrasonic radiation pressure. The ultrasonic tactile display reproduces high-resolution stress patterns with wide bandwidth on the skin. It is a multipurpose device for synthesizing high-fidelity tactile feeling, and useful to clarify the human tactile perception. The prototy...

In this paper, a design of LED display control system based on ARM and FPGA is proposed, according to module structure characteristics of the RGB three colors LED display and the dynamic scanning display of the LED display which is achieved by FPGA technology, this system uses ARM chip S3C2240 as the control core. with the help of the programmable logic device auxiliary, it completed the data s...

The basic components of the video signal comprises of Video information, Chrominance level and Sync. Pulses. The Grey scale signals are required to check the compatibility of the display device with composite form of the modern signals, which is affected by chrominance interferences. In this paper, we will analyse the multi format signal generators, which are utilised and has the capability to ...

This paper describes an object oriented editor for designing and running graphical user interfaces for control screens of the Distributed Object Oriented Control System (DOOCS). The whole DOOCS system [1] is based on the object-oriented methodology, i.e. devices are handled as objects, data objects are transferred between client and server programs and the data is visualized by display objects....
