Errata to "Understanding Multimodal User Gesture and Speech Behavior for Object Manipulation in Augmented Reality...

Area of Science:

• Cognitive Science
• Human-Computer Interaction
• Speech and Language Processing

Background:

• Accurate temporal measurement is crucial for understanding human-computer interaction and speech production.
• Previous research relies on precise timing data for gesture and speech initiation.
• Inconsistencies in data reporting can significantly impact research findings and conclusions.

Purpose of the Study:

• To identify and quantify reporting errors in temporal data related to gesture and speech initiation.
• To correct the reported temporal data for accurate analysis.
• To highlight the impact of data reporting inaccuracies on scientific interpretation.

Main Methods:

• Analysis of reported temporal data in milliseconds.
• Identification of discrepancies between reported and actual time values.
• Recalculation of time differences based on identified error patterns.

Main Results:

• Temporal data was consistently reported in 100ths of a second instead of milliseconds.
• Time differences between gesture and speech initiation were reported as 60% of their actual value.
• Actual time differences were found to be six times greater than initially reported.

Conclusions:

• Significant systematic errors in temporal data reporting were present.
• Corrected temporal data reveals substantially longer intervals between gesture and speech initiation.
• Researchers must exercise caution and verify temporal data reporting to ensure scientific validity.
