πŸ’Ž On the importance of timely feedback

For example, the clever people from Dulux paint recognised that an absence of visual feedback also wreaks havoc for exhausted DIYers looking to decorate white ceilings with white paint (it’s near impossible to know where you have already painted!).

Addressing this issue, Dulux created NeverMiss, a ceiling paint that goes on pink (providing clear feedback against white ceilings) and dries white, helping painters create a uniform finish. Likewise, to prevent ‘creepers’ edging over the speed limit, radar-enabled speed displays providing real-time feedback now reduce speeding by up to 10%. There are nappies that signal when they’re soiled, tissues that change colour when you’re nearing the end of the box, razorblades that turn green when it’s time to change the blades, and even tyres that wear away to reveal the message “change tyre” when your tread becomes dangerously thin.
