Ah, okay – so those school lessons do come in handy hey. But that’s for one finger, there are 28 fingers in the machine! How on earth do you ask the machine to recreate this on each robotic finger?
“Yes, can you imagine the amount of workload?! They have to be programmed to move in harmony to deliver different therapy programs. It is a really challenging task, just like a conductor instructing the musicians. The program tells a finger to move up, while another goes down. Not only that, it also controls how long the finger stays in a position so that it simulates the physical therapist holding his fingers to maintain the force. We worked very closely with Chongsu Lee, BackHug’s physio founder to ensure the device provides users with similar experience.”
Thanks to Truong, we now have a much better idea how Backhug works underneath its comfy exterior. Maybe next time we lie down on the device, we’ll be thinking about a conductor controlling 12 musicians to bring to you the best back care experience!
