After a considerable build-up, and revelations a-plenty already, CES finally opened the doors of its three show halls and welcomed crowds of consumers, industry experts, exhibitors and journalists in to the main event.

The Smart Home
The connected home and the increasing number of smart appliances has been a big theme of this years CES, with everything from washing machines to plant pots now feeding information to each other and learning your habits.

Among the innovations on show was the Petnet Smartfeeder, which holds around two weeks worth of pet food, and uses an algorithm that takes a pets age, weight, health and level of activity into account, as well as the type of food, to produce an optimised schedule of how much it should be fed.

The Smartfeeder connects to a mobile app, enabling owners to adjust feeding schedules and manage portion sizes, and sending notifications when food needs to be replenished.

Mobile health was also addressed, with Atericas new Veta smart case for EpiPens. Designed to replace the standard plastic cases used to carry and store EpiPens, which are used by people with severe allergies, the Veta case connects to your smartphone and notifies friends and family when it is used, letting them know you are suffering an allergy attack.

The case can also issue audible alerts and instructions to strangers or those unfamiliar with how to use an EpiPen on how to administer the medication in the event you are unable to, and even monitors temperatures changes that could affect the epinephrine within the EpiPen.

Connected Cars
The future of motoring technology has already been making headlines at CES, with Mercedes-Benz self-driving concept car and VWs gesture controlled displays. Today saw BMW and Ford reveal their innovations.

BMW had a variety of new technologies on show, including gesture control displays similar to Volkswagens, with in-car cameras enabling you to adjust the volume of your music by drawing a circle in the air, or answer a phone call by pointing in the right direction.

The company also demonstrated its driverless car solution, powered by its proprietary cloud technology, with a representative able to control a BMW i3 with audio commands via a smartwatch, and also bravely demonstrating the collision detection technology by stepping in front of the car as it pulled close.

Ford also threw itself behind the push towards driverless cars, with co-CEO Mark Fields saying he was focused on being the first auto company to produce a mass-market autonomous vehicle.

During his keynote speech, he noted that while other companies are likely to have self-driving cars first, “when we do come out with an autonomous vehicle, we want to make sure it is accessible and affordable to everyone.”

Wearable Tech
As well as Intels new wearable processor, the Curie, there was plenty of other personal tech on display today, such as the new SnapCam from iON Camera. Designed as an extension of the smartphone camera function, the 1.5-inch square camera weighs a little over an ounce, and can be attached to clothes, sporting gear or accessories with a clip or magnet.

The camera connects wirelessly to a smartphone using both wi-fi and Bluetooth, and shoots 8 megapixel photos or films HD and live-streaming video. Content can also be saved directly on the camera with a micro SD card.

According to iON, the tiny camera can shoot 5,000 photos in time-lapse mode, shoot an hour of live streaming video on a single charge, and boasts a seven-day standby life. It has a touch-based interface, designed to be super-responsive and easily facilitate social sharing.
