• Perception Space– The physical space
where the user’s attention is.
• Action Space– The physical space
where the user acts in.
• Design Principle:– perception space and action
space must coincide! [δ=0]– “Interlacing the display and
manipulation space” (Djajadiningrat, 1998, TU Delft)

Interaction Props: user study
Props design factors: form, size, material and metaphor:
An experiment was carried out to explore different design strategies.
Tasks were based on initial planning of an interior architecture.
Focus of the experiment was subjective opinion (n=12) about the bricks.
The bricks were ranked by user performance before (first number) and after (second number) task solving activity.

Different Prop Designs…
Ref: Napier (1956) classified grips into 2 different categories’precision grip’ and ’power grip’.

The Next Steps
• full-duplex audio connection
• additional interaction techniques, e.g. speech, handwritten input
• more 2 and 3D interaction possibilities
• video conferencing functionality for distributed cooperation

Future Directions…
Further research questions:? gaze/eye contact with remote partner
? variation of interface prop designs
? additional input technologies
? presence supported by full-duplex audio connection
And how to analyze human behavior in 2/3D space & time over a longer period?
