Many people have iPads, smartphones and PDAs. The challenge of creating an effective interface can be quite difficult. These small devices contain powerful technologies that make the user's life easier by allowing immediate access to the Internet. With this access, almost any type of information is available. However, without using your computer's keyboard or mouse, the WIMP interface (windows, icons, menus, and pointers) becomes useless. Fortunately, the technological world has adapted to these changes by creating new interfaces. Many of these interfaces are known as “post WIMP” interfaces. This document will introduce these new "Post WIMP" interfaces, show how they were implemented, and explore the potential challenges you will face when implementing these ideas.Introducing Post WIMPDefining Post WIMPPost WIMP interfaces rely on the interaction that the the user shares with the computer to manipulate and explore data without a keyboard or mouse. Many devices that are so common today do not have these tools and to perform the same functionality you need to apply different tools. A gyroscope is used to detect the angle at which a device is positioned. Built-in cameras are used to scan barcodes. These things are used to interpret data and interact with the computer. Interaction Properties Human-computer interaction must be maintained to complete the task at hand. Post WIMP ideas must follow similar rules. [3] stated: “The essence of these interfaces is, therefore, a set of ongoing relationships, some of which are permanent and some of which are engaged and disengaged from time to time. These relationships accept continuous user input and typically... middle of the paper ......production of human-computer interaction?.
