There are two search options:
1. An alphabet search where the letters of the alphabet are presented on a grid. Touching one of those then shows a list of words beginning with that letter.
2. A Word Search where you type the word or part of and matching words are shown in the list.
In both cases, once you have the list, touching a word shows either a video of the sign, or, if we do not have a video, a static image that depicts the sign.
All images and videos are stored within the app so that internet access is not necessary to look up a sign. This may be revisited if the app size gets too large and we may change it to pull the video in particular from the BSL Signbank website. This is not something we want to do as we see the strength of this app in the fact that it can be used off line. To be honest if you have good internet connectivity, you would be better off using the source websites shown below.
Please note that enormous thanks are expressed to British Sign (http://www.british-sign.co.uk) for their permission to use their static images and to the BSL Signbank project at University College London (http://www.BSLsignbank.ucl.ac.uk) for the use of their video database.
