Some Aspects of Designing All-In-One Personal Software Support for Human-Centered Computing

Human-computer interaction is a multidisciplinary field that aims to streamline and automate human activities that involve working with computers. This field includes IT support for mental processes, which is based on a human-centered approach that involves either human-centered computing or a focus on the individual user. There is a lack of universal software, so that the user must use dozens of different single-purpose software products to process large amounts of information; the user must adapt to the technology. Our research approach is based on the design of a so-called virtual knowledge, the basis of which is an ordinary database table, into which the user inserts his information in natural language. This informatics structure representing knowledge is controlled by the software Writing Pad (WPad). It is developed as an all-in-one tool to replace the dozens of software products that the user would have to use instead. It also reduces the number of user interfaces and the thousands of necessary mouse clicks between online links and offline paths. The paper explains this human-centered software design, including a demonstration of how we used the knowledge table when writing this paper. The use of such tables for visually impaired users in computer-based learning solutions is also described.
