— Motion blur is a significant display property for which accurate, valid, and robust measurement methods are needed. Recent motion‐blur measurements of a set of eight displays by a set of six measurement devices provided an opportunity to evaluate techniques of measurement and analysis. Both the raw data waveforms collected by each device and the metrics derived from those waveforms were examined. Significant discrepancies between instruments and variability within instruments were found. A new motion‐blur metric (GET) that exhibits increased robustness and reduced variability relative to existing metrics is proposed.
