This project called Interface Ergonomics was about finding new physical ways of interacting with devices and products we use every day. The interaction should be more exciting and intuitive than the buttons, switches and touchscreen we nowadays find everywhere.
The first use case for this cable interface is a charging cable. If the battery is empty the cable lies flat, but as it gets charged, it makes a bow that gets sharper. This lets the user see their phone‘s battery status at a glance without the need of any additional device.
In the second use case, the power chord of a lamp acts as an input device to control the lamp. By pinching the chord the lamp can be switched on and off. By sliding the hands on the chord closer to each other or further apart, the light can be dimmed.
