Peter ChengEmeritus Professor (Informatics)
Research
Peter Cheng's research spans:
- Cognitive science of representational systems / Knowledge visualization:
- Cognitive processing underpinning the use of graphical representational systems.
- Information visualization / visual analytics in conceptually demanding domains.
- Design and evaluation of novel diagrams and notations systems to support higher forms of cognition, such as complex problem solving, conceptual learning and discovery.
- Design and evaluation of novel graphical interfaces for information intensive tasks.
- Science and mathematics learning and instruction.
- Cognitive learning analytics:
- Measurement of competence in conceptually rich domains using millisecond behavioural signals in writing and drawing.
- Underpinning cognitive processes of writing and drawing.
- Methods and tools for graphical protocol analysis.
- Cognitive science of tactile graphics and haptic interaction:
- Nature of the cognitive processes of reading by touch.
- Design and evaluation of novel graphical materials for people with visual impairment
- Design and evaluation of novel touch interfaces for portable devices.
- Methods and tools for graphical protocol analysis.
- Symbolic cognitive modelling of problem solving with graphical representations.
- Cognitive biometric user authentication:
