Intangible Interaction: week one

Project #1: Redesigning Interaction

Group Member: Zoe Cohen, Peiyu Eva Zhou


The hand dryer is the most interesting and the highest technology thing we found in the bathroom, the air coming out from a paper-thin gap, and the hand dryer was covered with metal. And we wonder how it detects our hands and where they put the sensor?


The product name is Dyson Airblade V, so we researched; however, the result was confusing. We googled the parts, how to fix the sensor, how to install the product on the wall, even the product's design background, and everything was talking about their new digital motor...

We learned that Dyson designed this product to reduce bacteria; the product outlook was intended to fit everywhere. And the V shape can help users to dry their hands naturally, and their new motor can wipe the water faster within 12 seconds.

Finally, we found something on a video called James Dyson explains the Dyson Airblade V hand dryer. And its called (approximately) compacity sensor.

The capacity sensor - Capacitive proximity sensors are non-contact devices that can detect the presence or absence of virtually any object regardless of material.  They utilize the electrical property of capacitance and the change of capacitance based on a change in the electrical field around the active face of the sensor - and it means it can detect motion or objects through metal.

However, we could not locate where is the sensor...
