Q and I Listening Together

Introduction

Listening to music with a group of friends representing different preferences should be joyful. ‘Q and I’ is the perfect music system for you and your friends, enriching your shared listening experience. This design facilitates leverage to discussions by showing authorship through color in the queue, represented by rows in both shared interfaces. In this way, everyone can put in their favorite vibes on the digital interface, while present friends can notice when changes are made in the music queue from the tangible interface.

The aim of this respository is to share how the music-sharing prototype works (specifically the tangible prototype) from a technicial perspective and how to replicate such a prototype (maybe) in other peers' projects.

Techniques

(An overview of how the final prototype was structured)

Creativity and aesthetics

M1.1_SISS_Report-2

To improve the aesthetics of the prototype:

  • three different methods of the light diffusings were developed (see figure 1)
  • placing aluminum foyers (area A) underneath the LED strips to diffuse the light evenly (see method 2 and method 3)
  • three methods of transparent jointers for connecting each diffuser were applied ( Image 16). These methods allowed lights emitted from the LED strip to travel inside the diffusers and avoid leaving shadows. However, the second method required glues for connecting parts, which would leave the gluing marks on the acrylics and therefore the third method was introduced. (see figure 3, 4, 5, 6)

Credits

This was a highly colaborative design project finished with a group of four master students at the TU Eindhoven. The development of the tangible prototype was mainly and solely developed by @Sark P. XING, and the digital tangible (functional) was implemented by @OliviervDuuren, an interface where users can add songs through and update the database for the NodeMCU to read wirelessly. The other members of the group, Seji Bernabela and Ward de Groot, mainly contributed on the GUI interface (demo) development and user research.
