UGS 302 Usability and User-Centered Design Day 3

Objectives After this class you will be able to (it is my hope!): Describe some eye physiology Explain how the visual system works (somewhat) Identify visual cues to depth Be able to describe what it means to say “perception is not the simple sum of sensations.”

Whole point . . . Let’s design systems to fit people instead of the other way around.

Human Information Processing How do human beings take in and process information? Sensory psychology – how humans transform physical energy (e.g., light and sound waves) into sensory signals to and in the brain. Perceptual psychology – how humans interpret these sensory signals as perceptions. Cognitive psychology – how humans think about these perceptions, and previous experiences, and their own mental creations, and . . . Psycholinguistics – The psychology of language -- what goes on between the time I have a thought and you have the same (or similar!) thought, whether I say it or write it.

Sensation/Perception POINT: Perceptions are made up of more than just a collection of sensations! OTHER things influence our perceptions, e.g., Our experiences Our biases The context Our current emotional state Etc. So, what does that have to say about designing human-computer interfaces???

Perceptual Psy – Color Vision Color perception – 3 types of cones (RGB)

Perceptual Psy -- Depth Different visual cues to depth Oculomotor vs. Visual Oculomotor – Lens accommodation and extraocular muscle convergence are “read” by the brain Visual: Binocular vs. Monocular Binocular – Stereopsis (retinal disparity) Monocular (next screen) Static Motion parallax

More Depth Cues Monocular Static Motion parallax Interposition Size Perspective Linear perspective Texture gradient Aerial perspective Shading Motion parallax

Monocular Cues -- Interposition

Monocular Cues -- Size

Monocular Cues – Linear Perspective

Monocular Cues – Texture Gradient
