EECS 247, Spring 1997, UC Berkeley With the increasing popularity of multimedia PC’s and particularly multimedia laptop computers, there is an increasing need for high performance audio and video in the system. This paper reports on a stereo CD-quality D/A converter that has been developed for integration with a 3D graphics controller IC to help reduce the size and power of the multimedia subsy...

Industrial Robots are complex systems with hard real time, high safety, reliability and availability requirements. Robot Controllers are part of these systems and they are complex hard real time computers, which control a robot’s mechanical parts. To be useful, Robot Controllers must be programmable by end customers. This is typically done through a domain and vendor specific programming langua...

With the advent of digital computers the engineers felt the need of utilizing computer advantages in the industrial process through the centralized control system. This thought led to the introduction of direct digital control (DDC) phylisophy. In this paper the author has presented a brief review of the structure of DDC as well as its working with illustration. The two types of algorithm used ...

We present a simple controller for terrain navigation called Strider. The controller is based on the concept of walking and is implemented using a standard mouse device as used with virtually any desktop computer. Terrain can be explored at any detail by changing the height of the Strider. By applying a scale factor to the rate of change in position and Strider height based on the current heigh...

Gone are the days that computers will be used by select users sitting at a desk with a mouse and keyboard. The next wave of computing, ubiquitous computing, is upon us. With smart phones, tablet computers, and embedded sensors/actuators flourishing, users are already interacting with dozens of computers per day. A large body of research has addressed many issues in hardware and software for the...

Today we have computers in all kind of work places, and it is a fairly common artefact in many homes. What becomes an interesting topic when computers end up in everyday occasions and used by people who are not necessarily computer experts is how the user interface should be designed to be rendered practically useful. This thesis explores part of this problem by looking into the details of how ...

A variety of techniques have been proposed to manipulate objects in three dimensions using only a two-dimensional input device, such as a standard mouse. Some of these methods lacked full six degree of freedom (DOF) control, instead manipulating only the two DOF orientation of the object. Others provide six DOF control at the cost of complex user operations and complex implementations. We exten...
