UX of radio waves Week 2 of 2
Term 1 week 8
Team

Our environment is saturated with radio waves. Mobile phones and their base stations, smart meters, satellite communications, radio and TV broadcasting, microwave ovens all use radio frequency electromagnetic emissions to function. Design an embodied experience of radio waves.

Ideas
In addition to the idea of human routers, we also explored the concept of an obstacle course. In this experience, strings would represent radio waves and bells attached to them would signal moments of disruption as users moved through the network.

Figure 1c. Integrating the obstacle course with the human router.

We decided to integrate the obstacle course with the human router idea because we felt they complemented each other well (Figure 1c). We imagined the obstacle course would spread from the human router’s body, making the experience embodied and material.

Testing

We wrapped string around the human router’s fingers, exploring how it might feel if the obstacle course was controlled by someone’s hands. Once we tied the other end of the string on chairs though, we realised that the setup was too small. The idea felt promising, but the obstacle course needed to be bigger so we could test the mechanics properly.

For our second round of testing, we wrapped string around the human router’s torso. Instead of tying the strings to chairs, we held them in our hands while a user moved through the obstacle course (Figure 5c). The interaction felt playful, but the obstacle course itself was still too small to make for an engaging experience.

In our third test, we wrapped string around the hands and legs of two human routers. This made the experience more interactive for everyone involved, though the strings were a little uncomfortable for the human routers and the course still felt too small. We were unable to document this exploration, so I have included a sketch of this attempt instead (Figure 4).

Using our bodies helped us realise that to add more height, we would need to start from the human router’s head. Our earlier attempts also showed that if we wanted to achieve a larger obstacle course, we would have to attach one end of the strings to the surrounding space instead of another person. That is when we started making a prototype that extended from the crown of the human router’s head through to the windows of our studio.

For our final design, we refined the human router’s headpiece and added bells on the strings. Our only instruction on presentation day was ‘Attempt to cross the obstacle course without disrupting any bells. Good luck.’



Room for growth
  • A diagrammatic analysis of our research would have allowed us to synthesise our findings without lengthy written explanations.

  • In the tutorial after our presentation, we disucussed that photographing the creative toolkit session would have been beneficial. It would have made it clear that the drawings were not produced by us, and easier to recall specific details had we needed to later in the project.

  • During our presentation feedback, it was suggested that we experiment with harsher sounds than jingle bells. I think it would be interesting to test this, and explore how sound alone could change the experience.

  • In our feedback, it was also noted that the experience could be enhanced by adding another human router at the opposite end of the course.

  • If I were to develop our design further, I would build on both feedback points. I would use the human routers to create a more complex obstacle course, and introduce low-pitch or electronic sounds to create an atmosphere. I would also test the design’s affordances more to explore how the human routers could move within space, and whether this movement might change the overall experience.

Figure 7. If I were to develop our design, I would reintroduce a second human router.
