Description:
To investigate user performance evaluation for different alarm forms on the digital interface under single dimensional information coding, such as color, shape, flash frequency, size and number, this study designed 5 visual alarm modes by following the design specification of visual alarm signal and carried out behavioral experiments for a certain radar interface. Based on the statistical analysis of accuracy rate and reaction time and comprehensive experimental interviews, the results reveal that, visual coding alarm form in the best identification performance is number and the worst is flash frequency. The research conclusions can be applied to the actual alarm interface design. It has a certain reference value for reducing the cognitive friction between the user and the digital interface, establishing a good man-machine cognitive matching relationship and perfecting the usability evaluation system of information coding.
