Floating speakers, connected hairbrushes, personal robots are just some of the bizarre range of new gadgets on offer as the 50th Computer Electronic Show in Las Vegas. Zoe Kleinman reports.

Steve Koenig of the conference organiser Consumer Trade Association tells her what he thinks the next big trends are, while tech analyst Carolina Milanesi explains why she thinks some trends may have been taken a bit too far already.

Zoe also gets to speak to artificial intelligence pioneer Andrew Ng of China tech giant Baidu about how the mainstreaming of AI may prove as significant as that of electricity a century ago.
