While looking at what the big box stores had to offer proved useful, we thought it was important to dig deeper and see what else was out there. We focused on materials that either enabled music devices or had embedded controls.
We looked at a range of online technology magazines for emerging technology for music devices, Eleksen's wearable audio controls, emerging design for hearing aids, Philips phototonic textiles, a mobile phone interface for the London underground (undersound), and fabric control research by Amy Hurst.
This research was extremely valuable when considering Plügg's features, design, and interaction.
