Disruptabottle: Encouraging Hydration with an Overflowing Bottle.

We present a prototype for a targeted behavioural intervention, Disruptabottle, which explores what happens when a 'nudge' technology becomes a 'shove' technology. If you do not drink water at a fast enough rate, the bottle will overflow and spill. This reminds the user that they haven't drunk enough, aggressively nudging them to drink in order to prevent further spillage. This persuasive technology attempts to motivate conscious decision making by drawing attention to the user's drinking habits. Furthermore, we evaluated the emotions and opinions of potential users towards Disruptabottle, finding that participants generally received the device positively; with 59% reporting that they would use the device and 92% believing it to be an effective way of encouraging healthy drinking habits.
