Abstract [en]

This thesis presents experimental results of shape’s influence on user’s performance in terms of time and accuracy in shape replication task. The shapes are drawn with mouse, pen and touch input devices. For this purpose, two non-meaningful, semi- randomly generated shapes have been used. The first shape has a combination of straight lines and curves whereas the second shape has curves only. Each of these shapes is presented in four versions namely contour, polygon, narrow tunnel and wide tunnel. A method to compare versions of these shapes with the corresponding versions of user drawn shapes is presented. In general, the results showed that the replication of second shape takes less time and the replicated shape is more accurate when compared to the first shape. In addition, performance of the input devices was found to be dependent upon the shapes and their versions they were used to draw.
