Shoes that help the wearer feel the virtual reality world they're walking in and a smart hair brush that can detect hair damage are among the early product highlights at CES.

The annual Las Vegas technology show draws companies and products from around the world to its convention centre to showcase their creations. Here are some of the first to grab the attention.

:: Taclim VR shoes
Developed by Japanese firm Cerevo, the shoes work in sync with virtual reality headsets and are worn alongside them, giving haptic feedback and vibrations to the wearer to give them a sense of walking on the virtual surfaces they see in front of them.

:: Hypersuit
Another extension to a virtual reality headset, the Hypersuit is a wearable simulator from French firm THEORY that gives the wearer the impression they have wings or can fly like a superhero.

:: Olly personal assistant
Described as a "robot with personality", Olly is a smart home hub that uses machine learning to evolve as you speak to it each day. The device is also able to learn and identify different members of a family and tailor itself to each of them and their likely commands.

:: Hair Coach
The result of a collaboration between hair care giant Kerastase, tech giant Withings and L'Oreal's Research and Innovation Technology Incubator, the Hair Coach claims to be the world's first smart hairbrush. It uses a range of sensors to spot hair damage and offer feedback to users on how to better protect their hair, including changes to brushing technique.

:: FridgeCam
As the name suggests, this is a small remote camera that sits inside your fridge. However, FridgeCam is also able to scan and identify bar codes on food, tracking expiry dates and notifying users when food needs to be eaten or thrown away.
