Summary:
iCanDraw? is the first system ever (EVER) to provide direction and feedback for drawing faces with a computer. The goal of iCanDraw? is to actually teach people how to draw the human face using actual metrics and techniques. It starts by generating a template of the face to be drawn so that the feedback can be tailored to the current task. Feedback is provided explicitly when the user finishes a step and asks for input. The system even includes some helpful features such as erase and undo gestures, reference line markers, and straight edges to provide guidelines. The user is led through drawing a face piece by piece, with help provided at the termination of each step. They can then choose to make changes or keep what they have. The users are not, however, constrained to certain steps and have the freedom to draw as much as they want or make past corrections.
The authors found 9 key design principles for assisting the act of drawing via sketch recognition. Also, they found out that users gained confidence after using the assistive system.
The omitted middle session of a different image with feedback turned on led to the user drawing a somewhat creepier and more correct baby.
Discussion:iCanDraw? software is in our lab, and I have even seen people use it, but I have yet to use it myself. And after reading this paper I want to! I think that having someone or something actively (but unobtrusively) provide feedback is an excellent way to hone ones skills without getting frustrated. I am guilty of "teaching" myself something and it being horribly, horribly wrong (you do not drive with both feet). Teaching tools are awesome. The End.
I completely agree, having tools that provide feedback is a very desirable thing and leads towards self-improvement. And it is not always easy to do it by yourself specially to detect what you are doing wrong, and since there is not always someone around to help a SW tool comes very handy. By the way, if someone has a standard drive car, now you know you should NOT lend it to Chris until you develop a teaching tool to use gas and breaks with only one foot.
ReplyDeleteI haven't use that before, lol. this system provides new way of solving HCI problem. like the idea!
