A PDA for the Bushman
Understanding the Reality Gap Between Technology Have's and Have Not's
Dr. Susan Dray was the featured speaker at the WUD 2005 Minneapolis event.
Dr. Dray is a pioneer in Human-Computer Interaction, and her firm in Minneapolis is internationally known for its work in human factors and user-centered design. She travels frequently to countries in South Africa and Asia to conduct usability studies for clients.
On one such trip, she observed User Centered Design professionals in South Africa who were able to develop a PDA interface that worked for illiterate bushmen. The bushmen would use their exquisite knowledge of animal habits to transmit extraordinarily valuable data to wildlife managers.
On another trip, she saw tuberculosis patients with cell phones get text message reminders to take their medications on schedule, and to take the full course of medication, even after symptoms disappeared. This system increased successful treatment of TB. Perhaps most importantly, taking the full course of medication helps stop the development of drug-resistant TB strains.
Why are technology development efforts in developing countries failing? For the same reason that products fail in markets everywhere, she says: lack of awareness of what user needs really are, the failure to develop products that meet those needs, and failing to continue relevant product support.
