     • ability to detect energy through sense organs
   • different from recognition
     • one can perceive without recognising the object

2. Approaches to perception

   • Gibson (1979) - Direct Perception
   • Marr (1982) - Information Processing
   • Gregory (1980) - Constructivist
   • Dual-processing
     • combining top down and bottom up processing
   • Gestalt approach
     • focus on perceptual organisation
     • different elements are grouped together
     • 2D only

3. Top down processing

   • Based on experience and prior knowledge (Gregory)

4. Bottom up processing

   • Combining the bottom up and top down processing
     • Dual-processing (Di Lollo), (Hupe et al), (Norma)
     • perception can be for both recognition and action
   • what you see is what you get (Gibson) and (Marr)

5. Perception for action

   • Direct Perception (Gibson)

6. Perception for recognition

   • Constructivist (Gregory)
   • Information Processing (Marr)
