>I came across 2 Sensor module recently released by ST Microelectronics:
There will be in the future probably very few mobile devices without such sensors. When we worked on the project TEA in 1999 it seemed far away… What can you do with sensors on the mobile? There are a few papers to read: using them for context awareness , for interaction , , and for creating smart devices .
Last week in Finland I met Antii Takaluoma (one of the co-authors of ) and he works now for offcode.fi – I saw impressive Linux hardware – I expect cool stuff to come
