Delay adaptation does not transfer between discrete button press actions and continuous control.

Area of Science:

• Human-computer interaction
• Cognitive psychology
• Motor control

Background:

• Humans frequently encounter action-outcome delays when using technology.
• Delay adaptation is a process where performance improves over time despite these delays.
• Previous research demonstrated delay adaptation across various tasks and control modes.

Purpose of the Study:

• To investigate if delay adaptation is specific to the control mode used.
• To determine if adaptation to delays transfers between different input methods.

Main Methods:

• Participants performed a target tracking task.
• Cursor control was managed using either a stylus on a graphics tablet or keyboard arrow keys.
• Adaptation to introduced delays was measured for each control mode.

Main Results:

• Delay adaptation was observed for both the stylus and keyboard control modes.
• No significant transfer of delay adaptation occurred between the two control modes.
• This suggests that adaptation is specific to the sensory-motor contingencies of the practiced control mode.

Conclusions:

• Delay adaptation is specific to the control mode employed during the adaptation period.
• Visuomotor adaptation to delays does not generalize across different input devices.
• Findings have implications for designing user interfaces and understanding human adaptability in interactive systems.
