South African conservation scientist Louis Liebenberg (and helped by former University of Cape Town computer scientist Justin Steventon) have developed a software for PDAs that assist Bushmen of the Kalahari Desert from being trackers to being cyber trackers. While most of the Bushmen cannot read or write, they are able to interpret the icons on their PDAs.
The PDA screen displays more than 40 animal species and plants. Anther set of icons cover activities such as drinking, feeding, running, fighting, mating and sleeping. Pressing an animal icon and than an activity icon records a sighting and or other finding. This digital recording which records time, date and exact location is than sent wirelessly to a computer server by satellite. That information is than processed on a base-station computer to create maps and charts of animal movements and feeding habits.
