Ex-Apple employee turned technology journalist Michael Grothaus proposes a tablet-powered means for customers wanting to easily keep closer track of their nutrition-- the SITU Bluetooth food scale.

The SITU shows the weight and  nutritional value of food the user plans to eat. It connects to iPads or Android tablets via Bluetooth, and a companion app calculates the nutrition value of the food in question, from calories to salt, sugars, vitamins and minerals. In other words, it promises to eliminate the need for calorie counting tables and the like.

The easy to use app even keeps track of entire meals, and provides a user history complete with nutrient limit alerts and data exporting options.

The more paranoid of visitors would have all reason to believe CeBIT 2014 is all about science-fiction as robots appear able to take care of anything from driving to even opening ceremony duties.

After all, the show was opened by a so-called "RoboThespian," an Engineered Arts creation designed for use as an educational guide. The robot was arguably the more amusing on-stage presence (in the least it was less mechanical than the "Digital Native") but alas it was too quickly carted off to make way for more human speakers.

Other robots occupying CeBIT include... pole dancers. No, really. Germany's Tobit Software decided to put the talents of British artist Gile Walker to good (?) use with a booth decked out as a nightmare club of the future compete with two robot dancers and a robot DJ with a megaphone for a head. The robot dancers are actually upgraded versions, having made a first CeBIT appearance back in 2012.

Mobile World Congress 2014 hosts more than smartphone and tablet launches-- Oral-B makes an appearance at the show with the SmartSeries 7000, a toothbrush with Bluetooth connectivity.

The toothbrush connects to smartphones equipped with an Oral-B app and, as the company puts it, guides users through fully personalised brushing routines. As one does.

Meanwhile the app monitors brushing progress in realtime, telling users to move to different parts of the mouth or whether they are brushing too hard. It also allows dentists program individual brushing programs according patient needs.

"It will guide you in terms of how to brush, and you will be able to fully personalize the brushing routine for you," the company tells Reuters.

Startup YEI Technology proposes a wearable means for customers wanting more immersive gaming and, perhaps, a spot of exercise-- the PrioVR, a motion-sensing suit able to turn body movements into in-game actions.

First seen at CES 2014 as a working prototype paired with the Oculus Rift VR headset, the PrioVR comes in Lite, Core and Pro versions. The Lite is an upper-body only suit with 8 sensors tracking the torso and arms. The Core is a full-body number with 12 sensors torso, arms and legs, and the Pro boosts sensor count to 17 for a system YEI claims is suitable even for professional motion capture.

"Inertial" sensors promise 360-degree low-latency real-time motion tracking, without need for Kinect-style cameras or additional equipment. Connectivity is wireless (YEI does not specify the technology in use), and the system handles multiple simultaneous users.
