- We're live from this year's Innovation Show in Brazil and we're very lucky to have top American innovator and designer Ruth Martin, here with us today. Welcome to the show, Ruth.

- Thank you for having me.

- So, Ruth. Tell us, what is your favourite gadget in the show so far?

- Well, some of the smartphones are brilliant. But if I had to choose one gadget to take home, it would be the Q-watch. It's an amazing all-in-one watch, phone and camera that you can also use for surfing the internet and social networking. And it looks so good, too! It comes in purple, pink, grey, red, brown and black. You can choose cotton, metal, leather or plastic straps.

- So, you think wearable technology is here to stay?

- Yes. It's a great mix of technology and fashion, I think!

Taking a walk in the park could help those suffering from depression, researchers have found.They studied whether a nature walk could improve the mood of people with clinical depression.The research also tested theories developed in a cognitive science field known as Attention Restoration Theory, which propose that people concentrate better after spending time in nature or looking at natural scenes.According to ART, those in peaceful settings are not bombarded with external distractions, which tax their working memory and attention systems.As a result, the brain can relax and enter a state of contemplation, which helps restore cognitive capacities.For the latest study, 20 people with clinical depression – 12 women and eight men, with an average age of 26 – took part in an experiment that involved walking in a quiet nature setting and in a noisy urban setting.Before their walks, participants completed testing to determine their cognitive and mood status, and were asked to think about an unresolved, painful memory.They were then told to go for an hour-long walk in a woodland park, or stroll along a busy street.
