Compare these with computers, information channels, memory and processing.
possible mismatches - size, speed, range and resolution.
Interaction, execution-evaluation cycle, interaction styles.
Menu-design, grouping like with like, size of groups, ease of locating functions.
Graphical User Interfaces, WIMP interfaces, virtual windows vs multiple superposition.
UIST conferences and recent topics. Icon design, clarity, distinctness, cultural background and assumptions.
Use of colour, need for high contrast, choice of colours, opposites vs related shades.
Colour blindness, theory, results, recommendations for choice of colour in interfaces. Examples of powerpoint templates and colour schemes.
Natural interfaces, current state of the art in handwriting recognition.
Visualisation methods, example of data sonification.
Evaluation of software?
