Fluid Sketches: Continuous Recognition and Morphing of Simple Hand-Drawn Shapes

James Avro and Kevin Novins

Summary

The authors introduce a new form of visual feedback about sketch recognition. Feedback is provided as shapes are drawn. The approach beautifies portions of the current stroke to reflect the recognition systems understanding of what is being drawn by the user. The approach works for two shapes, circles and squares.

Discussion

The approach is novel and interesting. There are two main problems I find with this work. One, it only works with two shapes. Two, they don't evaluate the effects of the feedback on human attention. Does it disrupt drawing? Do users find themselves waiting for feedback before drawing too far into a stroke?
