Lights reminding you to turn things off

Lights reminding you to turn things off

Duncan Drennan, who writes the very thoughtful Art of Engineering blog, notes something extremely interesting: standby lights, if they’re annoying/visible enough, can actually motivate users to switch the device off properly: Our DVD player has (to me) the most irritating standby light that I have […]

One-way turn of the screw

One-way turn of the screw

One-way screws, such as the above (image from Designing Against Vandalism, ed. Jane Sykes, The Design Council, London, 1979) are an interesting alternative to the usual array of tamper-proof ‘security fasteners’ (which usually require a special tool to fit and remove). There’s a very interesting […]

Dishonourable discharge?

Dishonourable discharge?

Long overdue, I’m currently reading Bruce Schneier‘s excellent Beyond Fear, and realising that in many ways, security thinking overlaps with architectures of control: the goal of so many systems is to control users’ behaviour or to deny the user the ability to perform certain actions. […]

Another charging opportunity?

Another charging opportunity?

Last month, an Apple patent application was published describing a method of “Protecting electronic devices from extended unauthorized use” – effectively a ‘charging rights management’ system. New Scientist and OhGizmo have stories explaining the system; while the stated intention is to make stolen devices less […]

Making energy use visible

Making energy use visible

Photos courtesy of Harry Ward We’ve looked recently at water taps with meters built in, the thinking being the ‘speedometer’ approach to shaping users’ behaviour – making users aware of the scale/rate/level of some activity should cause them to adjust that behaviour. A number of […]
