想做而没有做的。。。建设性意义

We selected this task for several reasons:
1) We are interested in using two-handed input to enhance curve editing. While the task does not truly reflect a practical way to perform curve editing (for example, most curve editing involves the manipulation of more than 2 CVs), we hope that what we learn about two-handed input from this simple curve editing task can be applied to more realistic curve editing situations and different problem domains.
2) We believe that for this simple curve editing task we can create a two-handed interaction technique that supports conceptual, visual and input space integration, thus avoiding some of the pitfalls of two-handed input.
3) We believe that curves which are difficult to match will require high amounts of manipulation and exploration. We believe that this task is a strong candidate to bring out the advantages of two-handed input.
