The system is part of Mitsubishi's new Wellness Navigator prototype. MIT's Technology review explains that the software and sensors will be able to take your pulse, analyze body fat, sample your breath and it even has a built in pedometer. The phone was on display at a big Personal Tech Show in Japan and the service will be provided by DoCoMo.
The phone can also track your food intake and keep you on your diet, perhaps suggesting exercise or more sleep. The demand in Japan and the USA for such a device should be obvious indeed. Checking breath is not as difficult as you think since each odor produces minute amounts of gas and the breath plume can be easily analyzed for instant feedback.
The Online Think Tank did a big study on this concept previously with a device called the "PHD" or "PHD +" Personal-Health-Device and considered all the potential side applications, including a website link in for a small fee, which would help users visualize their health online from their phone, wherever they are. The Mobile Cell Phone Industry is going high-tech with an all in one portable system capable of everything you desire, that future cometh. Sincerely, Lance.
