NTT Do Co Mo research and development team are now presenting future accessories that can be seen at its CEATEC booth in Japan. They are presenting the bad breath, hunger, body fat, and food ananlyzers.
The bad breath ananlyzer can also be used as a blood alcohol level tester and it determines your body fat content. All you have to do is enter your gender, weight, height, and waist size. Then when you are done, it determines your fat and muscle percentages.
Another gadget is the hunger analyzer. It determines if it time for you to eat and and wether or not if you are in a position to burn fat with exercise. All you do is blow into the device and it will show you the percentage of your level and the fat buning test brings your results as well.
There are many other cool gadgetsat the CEATEC booth that are worth cheching out. Even though they are prototypes without a specific release date and will probably only be available in Japan, they are really awesome!
