Output device

Summary

An output device is a piece of computer hardware that converts information into a human-perceptible form or, historically, into a physical machine-readable form for use with other non-computerized equipment. It can be text, graphics, tactile, audio, or video. Examples include monitors, printers, speakers, headphones, projectors, GPS devices, optical mark readers, and braille readers. In an industrial setting, output devices also include "printers" for paper tape and punched cards, especially where the tape or cards are subsequently used to control industrial equipment, such as an industrial loom with electrical robotics which is not fully computerized. Visual Electronic visual display A display device is the most common form of output device which presents output visually on computer screen. The output appears temporarily on the screen and can easily be altered or erased. With all-in-one PCs, notebook computers, hand held PCs and other devices; the term display scre

The goal of VR is to embed the users in a potentially complex virtual environment while ensuring that they are able to react as if this environment were real. The course provides a human perception-action background and describes the key programming techniques for achieving efficient VR applications

Machine learning and data analysis are becoming increasingly central in many sciences and applications. In this course, fundamental principles and methods of machine learning will be introduced, analyzed and practically implemented.

This course teaches basic knowledge on haptic devices, force feedback and mechanical man-machine interfaces. Lectures are about 40 %, the rest is hands-on practical work with the "haptic paddle", a complete mechanical device with full laptop control interface. Realization of project in groups of 2.

Development of SCARA-Type Haptic Device for Electrostatic Non-Contact Handling System

Benjamin Burns

This paper describes the development of a SCARA-type haptic device, which will be used to assist a human operator in non-contact object handling of silicon wafers using electrostatic levitation. The device has three degrees of freedom, of which only one (vertical) is actively controlled. By utilizing the admittance control paradigm, a high vertical stiffness and a high output force can be achieved. These properties are necessary for the intended application of non-contact object handling to prevent instabilities (induced by the human motion) of the electrostatic levitation system. As the nominal air gap between object and electrostatic levitator is in the order of 350 micrometer, with an allowable position error of about 150 micrometer, instability can easily occur if there is no haptic assistance, especially in the picking up or placing process. The developed SCARA-type haptic device has a mechanical stiffness of 51 N/mm for the vertical direction when it is in the weakest posture, which is sufficient for the non-contact handling task. The design and performance of the haptic device for the active vertical degree of freedom are described in this paper.

The Pyramic architecture is a flexible 48-microphone array mounted on a powerful FPGA-SoC system. It allows to do massively multi-channel audio processing in real-time. This project implements an extension to the original system. In the original system, audio output is not allowed from the hardware processor system of the SoC, thus we cannot perform simultaneous capture and output. We implemented this through the design of an audio output controller, as well as a library (libpyramicio) that drives the capture and output from the software part and makes it easy for application developers to create algorithms that run on the Pyramic array.
