Computational cellphone microscopy
ACM SIGGRAPH 2012 Posters on - SIGGRAPH '12, 2012Within the last few years, cellphone subscriptions have widely spread and now cover even the remotest parts of the planet. Adequate access to healthcare, however, is not widely available, especially in developing countries. We propose a new approach to converting cellphones into low-cost scientific devices for microscopy. Cellphone microscopes have the

You're enjoying a rare bit of peace and quiet, perhaps dozing on a train, when someone begins a loud cellphone conversation nearby. Electromagnetic countermeasures are available to reclaim the silence, but for the most part they are illegal. In the United States, for example, only federal agents can legally use signal jammers to block cellular ...

Optimizing a Personalized Cellphone Keypad
2011Current layouts for alphabetic input on mobile phone keypads are inefficient. We propose a genetic algorithm (GA) to find a suitable keypad layout for each user, based on their personal text history. It incorporates codes for frequent multigrams. We optimize for two-thumb use, minimizing the number of strokes, and consecutive use of the same key or ...
