Study Notes
Visual Perception
- The eye transforms light into electrical signals, which are then sent to the brain for processing.
- As luminance increases, the rate of flicker also increases.
- The human eye interprets rapidly on and off light as constantly on.
Color Perception
- The eye perceives color as a result of the interaction of light and objects in the environment.
- Color perception is influenced by factors such as the wavelength of light, the surface of the object, and the surrounding environment.
Capabilities and Limitations of Visual Processing
- The human eye is limited in what it can perceive.
- Visual perception can be influenced by factors such as environmental conditions, individual differences, and cognitive biases.
- Visual processing can create optical illusions.
Vision and Interaction with Computers
- The human eye and visual system limit what can be seen.
- The human vision system consists of two stages: reception of stimuli and processing and interpretation of that stimuli.
- Human computer interaction depends on the user receiving information output from the computer and providing input back to the computer.
