A study by Bonita Sharif and Jonathan I. Maletic from Department of Computer Science Kent State University about how the eye response to camelCase and under_score indentifier, or might be function or variable naming style.
Visual effort is determined using six measures based on eye gaze data namely: fixation counts and durations. Although, no difference was found between identifier styles with respect to accuracy, results indicate a significant improvement in time and lower visual effort with the underscore style.
personally, i like underscore rather than camelCase, it’s more readable and concise, and easily to read between word.
