Optimizing Screen Time To Heart Beats
Kids spend too much time in front of a screen these days. They also won’t get off my lawn, and music today is just a bunch of static. They don’t respect their elders, either. While kids today are terrible, we can fix that first problem — sitting in front of a screen all day. For his Hackaday Prize entry, [Donovan] has created a device that optimizes screen time to reduce sensory overload. It’s the Optimote, the combination of a remote control and biofeedback.
The idea behind the Optimote is to actually to reduce stimulation when watching something on a screen. For many people, including people on the autism spectrum, watching TV or YouTube videos can often result in debilitating sensory overload. You can’t relax in this state, you can’t learn, and you certainly can’t get any entertainment value out of the glowing rectangle in front of your face.
The Optimote uses a pulse sensor, an Arduino, an incredible break-away cable that seems to be missing from any other wearable device like this, and a software stack that interacts with VLC. During periods of high pulse rate, the video skips to low-intensity footage. There’s a ‘calm’ mode that puts media volume and tempo in sync with heart rate. The ‘thrill’ mode plays an eerie scene looping with the Jaws theme.
So far, the prototype is a success, and [Donovan] is looking forward to large-scale user experience testing to determine how effective and enjoyable this technology can become.
