A display device is an output device for presentation of information in visual [1] or tactile form (the latter used for example in tactile electronic displays for blind people). [2] When the input information that is supplied has an electrical signal the display is called an electronic display .
In interactive mode, the eye-tracker is used as an input device. From a general point of view, an interactive system responds to the observer's actions and interacts with them. Because the display updates in response to the observer's eye movements, the gaze-contingency paradigm can be classified an interactive eye-tracking application.
A tachistoscope is a device that displays a picture, text, or an object for a specific amount of time.It can be used for various purposes such as to increase recognition speed, to show something too fast to be consciously recognized, or to test which elements of a display are memorable.
A display's legibility is critical and necessary for designing a usable display. If the characters or objects being displayed cannot be discernible, the operator cannot effectively use them. 2.Avoid absolute judgment limits. Do not ask the user to determine the level of a variable based on a single sensory variable (e.g., color, size, loudness).
Self-organizing systems: Systems that typically (though not always) display emergent properties. Steady state: A state in which the variables (called state variables) which define the behavior of a system or a process are unchanging in time. In chemistry, it is a more general situation than dynamic equilibrium.
Affect displays are the verbal and non-verbal displays of affect (). [1] These displays can be through facial expressions, gestures and body language, volume and tone of voice, laughing, crying, etc. Affect displays can be altered or faked so one may appear one way, when they feel another (e.g., smiling when sad).
An electronic visual display is a display device that can display images, video, or text that is transmitted electronically. Electronic visual displays include television sets , computer monitors , and digital signage .
[A] [a] In psychology, a conceptual system is an individual's mental model of the world; in cognitive science the model is gradually diffused to the scientific community; in a society the model can become an institution. [b] In humans, a conceptual system may be understood as kind of a metaphor for the world. [3]
