Error analysis of task performance with laptop in vibration environment

The present study investigates influences of vibration directions, vibration magnitudes, object sizes, object distances and angles of approach on producing errors while performing pointing and clicking activity on a laptop monitor similar to passengers working on moving trains. Attempts made outside the boundary of an object while performing the activity is registered as an error. The number of errors produced under different exposure conditions is computed. Higher vibration magnitudes, smaller size of the objects, and diagonal angular movements are found to create more errors and affected accuracy of the activity and hence showed difficulties to perform the activity.

► Detailed study on the effect of vibration on accuracy of object selection task.
► Reports the effect of object sizes and its positions on accuracy of task under vibration.
► Multi-axis, higher magnitude vibration, and smaller size objects induce more errors.
► The effects of angle of approach are sensitive to mouse movement direction.
