Doug Englebart’s team proposes a demo of how the data are related to another, and how it’s classified, using the prototype of an early computer and the three tools: mouse, keyboard, and a keypad. Doug Englebart types the text on the blank screen. There’s a beep sound for every aspect of the action. There are metadata, showing a file’s name, author, and date. This metadata is displayed on a modern computer. He moves the mouse around through a horizontal and vertical wheel. He clicks the pointer at the sentence on-screen and drags it from one end to another. Then he simultaneously connects the keypad to perform duplicate. The process is a combination of two cognitive processes, choose a particular part, and copy and paste that. Nowadays, the process is similar, drag from one point to another and press Ctrl+C then Ctrl+V, which is a direct successor of Englebart’s demo, or right-click the mouse showing various executions, including copy and paste. He demonstrated modifying the hierarchy of the multiple files. The metadata of individual file now assesses the order of the files: date added, size, type.
Doug Englebart’s team had trouble with some links, which there was a blank screen, not showing up in any directory. The insert instrument has evolved with the touchpad’s introduction, which replaced the traditional combo of mouse and keys. Jump and return authorize the content to go to the previous or later stage. However, the button replaced the return key as it could affect other aspects of the system, such as removing a letter on the search or file on the folder.
I like how you talked about the mishaps of Englebart’s demo and the frustrations he probably went through when his screen was bugged and his directory was not functioning properly.
