Acorn computer inventor: Interactive objects big in 2014

Acorn computer inventor Herman Hauser has been talking about how he thinks future technology will develop, including robots that can learn to ride a unicycle faster than a human.

Many felt Acorn's technology was superior but Apple managed to sell its products to become the world's biggest company, and Mr Hauser now spends his time and money investing in new companies.

He told the BBC's Chloe Hayward that the next big thing would be the "internet of things" - or objects that are capable of interacting with each other.
