A multimodal user interface allows users to communicate with computers using multiple modalities, such as a mouse, a keyboard or voice, in various combined ways. This paper discusses a multimodal drawing tool, whereby the user can use a mouse, a keyboard and voice effectively. Also, it describes an interpretation method, by which the system integrates voice inputs and pointing inputs using cont...

A touchpad is a common input device for notebook computers. However, pointing performance is poor in comparison with a mouse. This research is motivated by the need to improve the touchpad as an input device -to bring it closer to a mouse in pointing performance. To learn how users operate the touchpad during pointing tasks, we measured the force applied to the touchpad. We also measured the fo...

This paper presents a Fitts' law-based analysis of the user's performance in selection tasks with the Leap Motion Controller compared with a standard mouse device. The Leap Motion Controller (LMC) is a new contact-free input system for gesture-based human-computer interaction with declared sub-millimeter accuracy. Up to this point, there has hardly been any systematic evaluation of this new sys...

Computers are widely used for business and entertainment purposes throughout our modern lives. Computer kits provide a variety of services such as text processing, programming, shopping, gaming. have greatly enhanced the quality lives; however, we discover an often-overlooked fact that engaging in computer-related activities may be eavesdropped upon by attacker sniffing emitted acoustic signals...

PID controller (which is an acronym to “proportional, integral and derivative”) is a type of device used for process control. As first practical use of PID controller dates to 1890s (Bennett, 1993), PID controllers are spread widely in various control applications till these days. In process control today, more than 95% of the control loops are PID type (Astrom et al., 1995). PID controllers ha...

800x600 as a tendency to use new technologies, gadgets such as laptop computers are becoming more popular among students, teachers, businessmen and office workers. today laptops are a great tool for education and learning, work and personal multimedia. millions of men, especially those in the reproductive age, are frequently using their laptop computers on the lap (thigh). over the past several...

This paper presents a new computer supported remote learning and gaming method using Tele-Face Mouse system. The Tele-Face Mouse system is being developed as a teleconference system. It converts simple desktop computers to a teleconference system. The main advantage of the Tele-Face Mouse system is that it enables people to share a computer screen as a working space, and to interact with it usi...

increasing of word demand load caused a new distributed generation (dg) to enter to powersystem. one of the most renewable energy is the photovoltaic system. it is beneficial to use thissystem in both separately as well as connected to power system using power electronics interface.in this paper an optimal pid controller for photovoltaic system systems has been developed. theoptimization techni...

CHRISTIAn ZEIDLER – Control systems that automate and manage production are at the heart of process industries. These systems are networks of interconnected sensors, actuators, controllers and computers, often distributed across vast processing plants that help manufacturers run their operations safely and cost-effectively, minimizing waste and ensuring consistent product quality. In the past t...
