- 1HCI Consists of Three PartsHuman
Computer
Interaction - 2_____are the users of computers. HCI should always consider what users expect and need, what physical abilities and limitations they may have, how their perceptual systems work, and what they find attractive and enjoyable when they use computers.Humans
- 3Information is received and responses are given via several input and output channels:▪ visual channel
▪ auditory channel
▪ haptic channel
▪ movement - 4Information is stored in memory:▪ sensory memory
▪ short-term (working) memory
▪ long-term memory - 5Information is processed and applied:▪ reasoning
▪ problem-solving
▪ skill acquisition
▪ error - 6A _____ carries on its business in a much less obvious way. The information a computer contains and the operations it performs are represented inside the computer in a form that we can’t directly observe, binary digits encoded as two levels of electrical charge.computer
- 7_____ between users and computers occurs at the user interface which includes both software and hardware. People have to use computers or different embedded devices for different purposes. For this, they have to interact with these machines. Researchers have built different interfaces and methods for those. The designers and programmers look for a reasonable balance between what can be programmed within the necessary schedule and budget, and what would be ideal for the users.Interaction
- 8The interaction between the user and the system has four parts:▪ User
▪ Input
▪ System
▪ Output - 9It provides a means of expressing instructions to be computer directly, using function keys, single characters, abbreviations, or whole word commands.Command Line Interface
- 10A _____ is a list of options or commands presented to the user of a computer or communications system. A ____ may either be a system's entire user interface, or only part of a more complex one.menu
- 11Users, unable to remember a command or lost in a hierarchy of menus, may long for the computer that can understand instructions expressed in everyday words. Language is by nature vague and imprecise: this gives it is flexibility and allows creativity in expression. Computers, on the other hand, require precise instructions.Natural Language
- 12The user is asked a series of questions (mainly with yes/no responses, multiple- choice, or codes) and so is led through the interaction step by step. An example of this would be web questionnaires.Question/Answer and Query Dialog
- 13______ interfaces are used primarily for data entry but can also be useful in data retrieval applications. The user is presented with a display resembling a paper form, with slots to fill in.Form-Fills and Spreadsheets
- 14_____ stands for Windows, Icons, Menus, and Pointers (or maybe Windows, Icons, Mouse, Pull-down menus). _____ is the style of graphical user interface that uses the above-mentioned common widgets.WIMP
- 15__________ are the actions of a computer user moving a pointer to a certain location on a screen (pointing) and then pressing a button on a mouse, usually the left button (click), or another pointing device.Point and click
- 16Virtual reality is one of the best examples of three-dimensional interfaces, but VR is only a part of a range of 3D techniques available to the interface designer.Three Dimensional Interfaces
