NTT DoCoMo App Nutrition Service
Lots of interesting, useful items were featured at NTT DoCoMo's display, including a Geiger counter attachment for a mobile phone. My favorite tech demo was of a service that used the camera on an Android phone to capture a picture of your meal, communicate back with the servers, and then identify the nutritional information accordingly.
Panasonic Waterproof Tablet and Portable TV
Just in case you've been hankering to take your tablet into the bath with you, Panasonic has the solution. The company showed off its recently released waterproof SV-ME970, a portable 7-inch TV for the Japanese market that runs a Web browser and has a YouTube app.
The screen resolution was unimpressive -- 800 by 480 pixels -- so the tablet isn't necessarily the best place to look at your digital photos, even if it does have a high-capacity SDXC card slot.
