7thSense in Rhythm with Chicago Museum of Science and Industry Giant Heart
For the real-time mask control that allows guests to fade the external view down at the same time as the internal view fades up, 7thSense added a Dynamic Transparency feature to Delta. This enables the guests to use a simple slider control to adjust the level of the internal view, relative to the external one.
Another key element of the Giant Heart – and perhaps its single most compelling feature – is its ability to synchronise its beat with that of the guest, so that the audio and video of the pre-programmed movies are matched to the visitor’s heart rate, as read into the system via two handgrips on the touch console. This amazing interface between a guest and the Giant Heart was made possible by BBI and Chicago-based leading fitness manufacturer and pulse capture interface company, LifeFitness.
For 7thSense, this posed yet another technological challenge, as Macpherson explains: “Delta was designed as a fixed-rate movie server, but for this project we added the ability to send in a simple external control command which alters the playback rate to the incoming demand immediately. Not only does this keep the audio in sync with the video, it corrects its pitch in real time so that the sound itself is not altered as the tempo changes.”
BBI proprietor Mark Roos concludes: “7thSense technology is extremely capable to begin with, but for this project the company really went the extra mile – adding unique features to Delta, assisting with the on-site integration and alignment, and generally making themselves available whenever we needed them. To pull off a project such as the Giant Heart, with its multiple channels of seamless projection and synchronized Dolby 5.1 surround audio, is never an easy task. Having partners such as 7thSense just helps everything run that little bit smoother.”
