Next Big Thing – physiologically personalised movies

Sweat more, scare more – that's the formula for a new breed of apps and interactive films headed straight for your shiny mug

Apps that read my sweat? After you.

Don't be scared, the Sensum wrist-mounted sensor and accompanying app wants to entertain you not embarrass you. It measures your galvanic skin response (GSR) while watching videos then sends the sweaty data to your phone via Bluetooth. That generates a graph to show your levels of engagement plus how it compares to others.

What kind of movies we talking about?

Less hot and heavy, more Fright Night – the idea is to be able to reward you for getting involved in jumpy horror films, for example. Filmtrip demoed an interactive short film at SXSW back in 2011 in which the audience's GSR and heart rate were measured so that the movie could get gorier the more excited the audience got – now it's working on a full-length sci-fi movie with multiple endings.

Better keep my cool.

Don't – if you do, you'll miss out on unlocking tailor-made soundtracks, characters, special effects and plot twists. Chances are it won't stop at movies either – online comics and video games could become much more interesting if Sensum takes off.
