Jan Chipchase is Principal Researcher in the User Experience Group of Nokia Research Center. A part of his fascinating job is to observe and describe how different cultures use mobile technologies differently - often in ways unintended or unpredicted by the industry that he represents.
He has carried out ethnographic fieldwork around the world, such as in Uganda where access to electricity and mobile phones is limited and the user need thus quite basic.
As a consequence of these limitations, people have developed an alternative solutions and service economies, such as phone-sharing systems and battery-charging services (photo) where batteries can be recharged for a relatively small price.
