Movement transformation on multi-touch devices: Intuition or instructional preparation?

Area of Science:

• Human-Computer Interaction
• Usability Engineering

Background:

• Multi-touch technology is prevalent in modern computing.
• The intuitive interaction differences between direct and indirect multi-touch devices are not well understood.

Purpose of the Study:

• To identify interaction difficulties with indirect multi-touch devices.
• To apply action regulation theory and movement transformation principles to gesture utilization.

Main Methods:

• An experimental study involving 54 subjects.
• Utilized an Apple Magic Trackpad for common computer tasks.
• Collected data through gesture analysis and User Experience questionnaires.

Main Results:

• Gestures on indirect multi-touch devices are not intuitively used without guidance.
• Instructions are necessary to overcome conceptual challenges in indirect gesture use.
• Gesture use impacts product assessment, but prior direct multi-touch experience does not.

Conclusions:

• Product developers should use video instructions to enhance the sense of intuitive interaction.
• Addressing conceptual difficulties is key for indirect multi-touch device usability.
• Direct multi-touch experience does not transfer to improved indirect multi-touch interaction.
