This resource is a well-done visual dictionary of American Sign Language (ASL), and conssists of an alphabetical index and content frame. The content frame displays a looping video of the performance of the selected word along with a text description of how to sign the word. I was able to spend about 30 minutes, finding words of interest and seeing their sign performed, of this extremely well-done system. The video is quick and efficient, automatically looping several times. The user interface is not terribly elegant, but it serves the purpose and is not cumbersome. This resource would be an excellent resource for students in communication, speech & hearing, etc. fields. Though not necessarily an tool for communicating directly with the hearing impared (Wait a second, let me watch this video...), it would be great tool for learning and reviewing a large number of signs or could serve as a resource for more obsure words / signs. It's ease of use is one of its most positive features. Scrolling and clicking are the only skills required for use, making this resource valuable at ALL levels of education.
