Traffic Lights of the Body (2023)

Interactive installation on a sex-ed exhibition (second iteration)

An interactive installation in the 2023 sex-ed exhibition, I Have Asked Many People About You, by MAYLOVE, Guizhou Huachengxinghe Culture Co. Ltd., and PLUCK. The exhibition venue is at Wonderful Square, Guiyang.

Themed signpost on the outdoor ground of the square.

Reach out the hands and light up the body parts on the “body textbook”. Observe the different colours of the lights, and see the children’s understandings of privacy regarding their own bodies.

Interaction hint. “This is an interactive exhibit: after touching different parts of the simulated human body, you can see which parts of the body are ‘safe areas’ that can be touched by others, and which parts are inviolable as in ‘Taboo Boundaries’.”

This time I was again responsible for the implementation of electronic technologies. Artwork design by MAYLOVE member Annie. Compared to the 2022 revision, this one changes the technical approach to capacitive sensing, resulting in a coherent, aesthetically pleasing display surface. The circuit is integrated on a printed circuit board, with the majority of components assembled and tested on-site. Throughout the setup process, tremendous aid was received from the MAYLOVE members, exhibition volunteers, and external participants. Gratitude goes to Sea, Milky, Annie, Haihan, Qiqi, Haizi, Huajiang, Feifei, Jiayan, the little sister, and Li (in order of appearance within each group) together with a lot of friends who did not leave behind a name.

Diagram the back side of the installation. Copper sheets are connected to the microcontroller through wires. A partial zoom-in diagram on the side depicts the copper sheet fixed to the wires with conductive tape, or alternatively, the sensing area directly formed with conductive tape.

Back side. Text in purple: “sufficient to leave wires overhanging; consider fixing them to the panel with tape, if sensitivity becomes a concern”.

Diagram of the internal layer of the installation. This comprises light strips of different colours — red, yellow, green — each with positive and negative leads extended onto a 12 V power supply, and with another lead extended to a dedicated microcontroller pin.
