Sometimes projects come along that draw us outside of the realm of multi-touch table development, challenge us in new ways, and allow us to show off the full range of capabilities that Ideum’s multi-talented staff offers, from graphic and user-experience design to software development, content creation, engineering, industrial design, animation, and hardware development. Recently, Ideum collaborated with Exploratorium’s Global Studios on one such project to build a series of interactive exhibits for a new science center in Turkey. The Exploratorium is a premier, interactive science museum in San Francisco, but they also make their services available to clients around the world through their Global Studios department.
The three first-of-their-kind interactives focus on a wide range of scientific subjects, and present information to visitors in a wholly engaging way.
In one interactive, visitors play a game to learn about star identification. At the heart of the activity are 3 prop “telescopes” through which visitors view star types and their corresponding spectral patterns. Through the telescope viewer and its associated Windows Surface Tablet touch display, visitors try to correctly identify a star based on its spectral pattern.
Ideum’s industrial designers and engineers worked closely with the team at the Exploratorium to develop these complex props, which were fabricated, assembled, and tested here in New Mexico. The telescope utilizes an embedded 4.3″ LCD screen to view each star. The stars move across the LCD as the visitor pushes the telescope from left to right. A rotary encoder embedded into a gear box at the base of the telescope relays positional data to an Arduino which then communicates that data to the application running on the Surface tablet.
In another interactive game, visitors learn about materials found in nature (wool, nacre, petroleum, etc.) by matching those materials with clues about their unique properties.
This interactive can be played in single-player or two-player mode. Each player has a set of 10 clear acrylic pucks that are embedded with natural materials and have a unique RFID tag on their underside. Clues are presented on the player’s touchscreen, and they must determine the material that those clues are referring to.
To answer, the player places a puck on an animated 32×32 LED panel powered by a Teensy microcontroller. An embedded RFID reader scans the tag from the puck and the user is presented with a different animation based on their response. The visitor receives visual feedback throughout the game, providing an arcade-like feeling. Points are awarded based on correct answers.
For the third application, Ideum developed the software for a large-scale, Magic Planet interactive. Global Imagination develops the compelling Magic Planet hardware, an internal projection globe that displays various, dynamic animations about Planet Earth. On a 32” touch-screen, visitors pull up various datasets on the 6ft diameter globe to learn the story about our changing planet–from plate tectonics to ocean currents.
In the coming weeks and months, we plan to share more details about this project through a larger case-study that will detail the various technologies that we experimented with and employed in order to bring these interactives to life. Stay tuned!
