We have seen the rise of smartphones and highly capable mobile computing platforms over a relatively short period of time. These devices are quickly becoming ubiquitous and already enable access to basic sensors to augment the excellent communication and computing capabilities. However, advanced sensor interaction has been limited. Readily available environment and health sensors cannot effectively leverage the smartphone yet. One such health application that holds much promise is breath analysis through laser absorption spectroscopy (LAS). Breath analysis can help augment existing diagnostic techniques with early detection. Technology advances have led to the development of portable LAS sensors that can monitor the user's health and the environment. Our demonstration will show such a portable laser sensor along with an event-driven data collection architecture to enable future personalized health applications.
