3D Projection Mapping with the Touch Board & Olga Kit
Beyondvis & Archvisual studios returned with another amazing project. This time, they built a 3D projection mapping installation using the Touch Board and Olga Kit.
Inspired by Japanese origami, they wanted to create a story which combines several different presentation techniques: a three-dimensional triangular faceted structure that is interactively enriched with unfolding animations, sequences that overlap and intersect with each other and, losing hard defined boundaries. The display has an element of surprise, making the audience actively hunt for the touch areas.
The main theme for the interactive projection was “Travels” – Poland in the 20th century. All the materials had been previously used in the permanent exhibition – “Miracle workers’’ for the National Museum in Wroclaw. This time they had been looking for a new interactive way to present the idea. The approach was to merge two different techniques and technologies.
They used Olga Kit by HeavyM as a canvas. This gave them freedom and versatility to create the desired 3D shape. They came up with the idea of combining this with Bare Conductive’s technology. Utilising the Touch Board’s capacitive sensing feature, they were able to add the interactive element. This was essential to unveil the full storytelling experience of this showcase.
They used copper sheets as touch sensors, which were placed on the inside faces of the Olga Kit. Simply ‘duct-taping’ them did the trick, although for permanent installations, a more robust method should be considered. These were located centrally in previously designated triangles; they could also be triangular and much bigger to cover almost the entire facet.
All sensors are wired back to the Touch Board. Cabling is hidden within the 3D structure, which is routed at the back. Active areas are easily engaged through Olga Kit. They used the Touch Board’s capacitive sensing, but the proximity feature can be adjusted through the Arduino code. For large scale installations, proximity values in the code can be bumped up so they engage even with passing by people in i.e. 0.5m distance, making it kind of a passive interactive experience.
They created animations in After Effects and used Mad Mapper software to map the animations onto Olga Kit. When sensors are pressed, they create engaging animations like unfolding origami. These happen randomly to the spectator – at least they seem to be, although they are predefined.
This presentation is a small scale mock-up of a bigger, 3D projection mapping wall idea with multiple Olga Kits and a random approach. It can be easily assembled, giving the full freedom to create custom structures.
The whole large-scale concept is driven by the idea of the ‘unknown’ active areas which unfold content, sometimes spanning over several metres involving groups of people standing in front of the wall to engage with the creative, ‘hidden’ story behind.
