The document discusses the application of ubiquitous computing (ubicomp) to address issues related to poverty in developing areas. It presents findings from field studies conducted in slums in Mumbai and Bangalore, India. The studies examined how residents currently use technologies like mobile phones and how technologies could be designed to better fit the needs and constraints of low-income environments. Key considerations for ubicomp design discussed are using human mediators instead of full automation, designing for disruptions, creating low-cost multi-purpose technologies, and accommodating both literacy and orality in interactions.
