The mouse is a very convenient and popular device used in data entry in desktop computers and workstations. For desktop publishing, CAD, paint or drawing programs, using the mouse is inevitable. This application note will describe how to use the COP822C microcontroller to implement a mouse controller.

The purpose of this explorative research was to explore the mood of a computer user and his or her use of keyboard and mouse. Twenty-six users (13 programmers and 13 frequent computer users) took part in the study. A background software application executing on participants’ computers logged the keyboard key press and mouse click events. The correlations between moods of the participants and th...

The dominant paradigm for programming a computer today is text entry via keyboard and mouse, but there are many common situations where this is not ideal. For example, tablets are challenging the idea that computers should include a keyboard and mouse. The virtual keyboards available on tablets are functional in terms of entering small amounts of text, but they leave much to be desired for use ...

The Universal Serial Bus is a complex and, therefore, a popular bus on personal computers and other devices. Many devices including disks, keyboards, mice, and network cards are attached to computers using it. The bus is a tree with hubs as nodes and devices as leafs and uses pol­ ling from the root of the tree, which is the bus controller. It permits hot plugging and removal of devices at any ...

A computer-controlled system is a synergistic coupling of the controlledprocess and the controller computer. We have defined new performance measures for real-time controller computers based on this

Objectives: Mouse is one of the most important data entry devices for computers. Undesirable and prolonged postures during work with the computer mouse increase workload, muscle aches and upper extremity musculoskeletal disorders. The present study aimed to evaluate and compare muscle activity during the use of 4 types of mouse, including trackball, trackpad, slanted and standard by Electromyog...
