How a Laser-Wielding Robot Will Help Fight Forgetfulness

What’s all the hype about Watchbot? 

If you’re like me, perhaps you jot everything down in a pocket-sized notebook. Maybe you are the type to fill your phone with alarms and reminders. You may even have a calendar on your desk, filled with important dates and events.

Whatever your method is, there is no shortage in ways people have attempted to overcome forgetfulness. It may seem like the premise of a sci-fi comedy, but researchers at Cornell and Stanford Universities have developed a new way to keep your habits and routines in check. That method? A laser-equipped robot made from some surprisingly simple materials.

The robot (known as WatchBot) is designed to help keep daily routines in check by pointing out forgotten steps with a small, low powered laser. This calls attention to the missed step in a minimally invasive, yet noticeable manner.

Watchbot made its debut at the International Conference on Robotics and Automation earlier this year. Crafted using a Kinect sensor, a tripod-mounted camera, a laptop, and a laser pointer, the robot is designed to silently observe routines. While observing, Watchbot learns the routine, everyday actions. When those patterns are broken, WatchBot points in the direction of the missed step.

Initial tests placed WatchBot in environments like kitchens and offices, observing routine, step-by-step based tasks, like cooking. If someone failed to put something away, such as a carton of milk, after pouring a glass, WatchBot would focus its laser on the carton until the action was corrected.

In the study, the researchers noted WatchBot’s potential for use in assisted living scenarios, rather than simply treating it like a futuristic personal assistant. Some speculate that WatchBot or similar mechanisms can be used to help those with degenerative diseases and conditions like Alzheimer’s, allowing patients higher levels of independence.

WatchBot is also a potential candidate for applications in the workplace, where skipped routines can lead to dangerous mistakes. A non-invasive monitor of safety might prove to be beneficial in manufacturing and other industries, where accidents and missed steps can lead to critical accidents and injuries.

LIA Showcases Potential Solutions to Laser Strikes on Aircraft

By Geoff Giordano

Despite significant criminal penalties, laser pointer strikes on aircraft continue to endanger flight crews, passengers and other citizens. Experts spotlighted the persistent problem by sharing potential solutions at the Laser Institute of America’s International Laser Safety Conference.

With nearly 4,000 laser strikes of aircraft reported annually in the U.S. since 2011, according to the FAA the need for educating the public is clear, according to LIA Executive Director Peter Baker and Education Director Gus Anibarro. When laser beams illuminate the cockpit of an aircraft, they can distract or temporarily blind pilots.

Several experts shared growing concerns about handheld laser devices during ILSC 2015 from March 23-26 in Albuquerque, N.M. Such devices, readily available from online sellers or at tourist destinations, are often mislabeled and more powerful than indicated.

Joshua Hadler, chief laser safety officer of the National Institute of Standards and Technology, detailed NIST’s method for determining laser pointer output. Many of the handheld devices he has tested exceeded the output listed on those devices. Continue reading

Laser Pointer Characterization and Evaluation at NIST

By Joshua Hadler

Using a low-cost apparatus designed to quickly and accurately measure the properties of hand-held laser devices, National Institute of Standards and Technology (NIST) researchers tested 122 laser pointers and found that nearly 90 percent of green pointers and about 44 percent of red pointers tested were out of compliance with federal safety regulations. The NIST test apparatus was designed so that it can be replicated easily by other institutions. Continue reading

Laser Pointer Prohibition – Improving Safety or Driving Misclassification?

By Trevor Wheatley

It is well known that since 2008 Australia has had some of the world’s most restrictive laws regarding the possession and importation of “laser pointers” with powers exceeding 1 mW. Following the purchase of a laser pointer that was misrepresented as legal in Australia, the question as to whether this strict legislation has actually improved safety concerning laser pointers is addressed. The legislation has been in effect for four years now, so one would expect that the ripples of change will have settled sufficiently that comparisons of pre and post implementation can be made.   Continue reading
