Poster design for the Practio Office

One of the last tasks I did at Practio was poster design for eight posters with the intent to decorate the office space, with a collection of cultural values and quotes. The posters consisted of seven small (700mm x 500mm) and one big (1500mm x 1500m) to summarize them all. My design task was to make a design that clearly could convey the information in a delightful way in the everyday office life. Inspired by the classical Swiss-style, and especially the work of Joseph Müller-Brockmann, I designed the posters with an aim to balance the communication of a clear message, with a layout that still would invite for examination of the content, while leaving a calm feel to the physical space.


My first drawing machine

A few month ago I decided to build a drawing machine, inspired by the many DIY and open source projects available online. I found the V-plotter type of drawing machine to be a good “beginner” drawing machine, and based on the software an essential principles by the Polargraph drawing machine by Sandy Noble I tried to build my own. One of my goals for this machine was to make it portable and easy to attach to different size of surfaces. I wanted it to draw on 1x1m canvases as well as 3x3m canvases, without changing anything on the design. I achieved this by making a clamp design for the motors, and small clamps for the strings, making it possible to adjust the length of the used string. Some of my first test drawings were processed using the Polargraph software and can be see bellow.

The next step for me, is to create a custom algorithm than can output G-code from generative drawings made with Processing.


Capacitive sensing + Machine Learning

During a four weeks project on Play and Ludic Interaction, I have explored capacitive sensing as a starting point for the project. During the first week my group and I have explored the qualities of different conductive materials when combined with capacitive sensing. We have been working with the Tact library by NANDstudio, which is capable to capture very rich data from the sensor. Different materials and objects each affordance different interactions, and this also affect which spectrum readings can be read by the sensor. E.g. when a jar of water is used as a capacitive sensor it peaks when the water is touched. Where a bag of wet sand peaks when squished tightly.

Through these explorations we have found especially two very interesting ways of using capacitive sensing:

  1. Its possible to create a “chain” of sensors that works through non-conductive materials (wood, glass, acrylic etc.). E.g. we had a path of aluminium foil that could sense proximity and touch on a jar of water, through a 4mm layer of wood/acrylic.

Classifying the data with Machine learning (we used Wekinator) can be used to recognize different gestures very well. This is mainly due to the rich data from the Tact library. We used 32 inputs pr. Sensor.

These findings have been the core for our project in Play and Ludic Interaction, and the mechanics we developed can be seen on the gifs/video. Hopefully I can soon share how we have applied this technology in a concept.


Ice cube painting toy

During a 2 days project of the course Play And Ludic Interaction, we were set to explore the creation of toys and playful interactions based on a material. Together with my group I was set to explore water. This resulted in a series of small experiments that each explored playful expression and characteristics of water.

The findings from this explorative process let to several ideas to water based toys. We ended up prototyping a maze that used ice cubes with food colouring, to paint abstract paintings. Inspired by generative art, our idea was to have our 11 co-students to each navigate an ice-cube through the maze to create individual paintings. The final toy, and the experiments can be seen below.
