By now you have surely driven in cars that illuminate your side view mirror when someone is in your blind spot, vibrate your steering wheel when you stray out of your lane and beep when you’re about to back up over your trash can. Your car might even have cruise control functions that automatically regulate your speed and braking based on how close you are to other vehicles. Cars use a combination of cameras and sensors to determine how far an object is from your bumper. The sensor is constantly analyzing the camera’s video feed in real time and alerts you with a vibration, beep or flashing light when you are too close to something.
If having this technology in your car has become novel, maybe it’s time to incorporate it on your construction site. While cameras and sensors are mostly used on job sites for security, these car technologies could monitor a whole range of things to maintain quality, efficiency and safety. But let’s focus on safety for now since one in five worker fatalities occur in construction. Cameras and sensors strategically placed on buildings, vehicles and vests, gloves and hard hats could help minimize the Fatal Four:
- Falls: Sensors could warn a worker if they are about to walk into a hole or sense when a guardrail is broken or missing. It could let someone know when a ladder is being used too far from the work that needs to be done so somebody doesn’t overreach and fall. Workers could also be reminded when they should be tied off and that they shouldn’t jump across scaffolding.
- Electrocutions: Sensors could tell electricians when an unsafe electric current is running through scaffolding near them or if there’s a live wire on site. They could notify someone if an electrical panel was ajar or if wire nuts or electrical tape aren’t appropriately adhered. Sensors and backup cams could also alert a crane operator when they are working too close to power lines.
- Struck by object: Wearable technology that uses sensors and cameras could vibrate when the worker is in the path of a moving object or vehicle. They could even cut the ignition switch if that vehicle was about to hit something or someone. This technology could also alert a crane or excavator operator when someone or something was in their blindspot. Sensors can also make sure cranes and other machinery are safely grounded.
- Caught in/between objects: This technology could automatically turn off a scissor lift that was about to trap someone against a ceiling. They could also alert someone if they are between two objects that could potentially pin them.
At the same time, 360-degree cameras with sensors could be mounted to a safety manager’s hardhat to literally give them eyes in the back of their head. The sensors would not only alert them if something outside their periphery was amiss or dangerous, but they would have the ability to record and survey the site to review later.
Still not convinced that this is ready for primetime? Well, the biggest proof point that these car technologies can be incorporated into wearable technologies for construction is Toyota’s Project BLAID. Worn over the shoulders, this device for blind people uses cameras and sensors to detect objects in the user’s surroundings the same way cars do. BLAID has speakers and vibration motors that help users locate bathrooms, escalators, stairs and doors. Given the fact that Toyota successfully migrated these cameras and sensors from cars to wearables, it’s easy to imagine how this technology could be used on a construction worker to help make the job site safer.
