During their E3 2009 Media Briefing, Nintendo announced the Wii Vitality Sensor. Yet another add-on peripheral for Wii, the Wii Vitality Sensor clips on to your finger and monitors your heart rate, transmitting it to Wii and whatever game you happen to be playing. Obviously this fits in to Wii Fit and Wii Fit Plus in some form, and could be used in interested ways for other games, but in all honesty, it just looks kind of annoying.
