I did some rough statistics lately about how catchbob users' manage to communicate through the freehand drawing interface. I code all those messages using a simple coding scheme that focus on the content (position, direction, signal strength, strategy, offtask and acknowledgement), the mode (textual or graphical), the position on te map (site specific or not) and the intent (announcement, question or order). The presence of the location awareness tool have a positive effect on the total number of messages, the position/direction/strategical messages. There is also more announcement and questions messages in the condition with the awareness tool.
