CLEVELAND–Researchers at Case Western Reserve College are utilizing wearable sensor know-how to develop an automated alert system to assist individuals stop smoking.

The smart-phone app, initially restricted to android-based working techniques, mechanically texts 20- to 120-second video messages to people who smoke when sensors detect particular arm and physique motions related to smoking.

There isn’t a scarcity of merchandise or programs–from nicotine gum to hypnosis–to assist individuals give up smoking. Extra just lately, wearable know-how has gained recognition within the struggle towards habit.

However the cell alert system Case Western Reserve researchers are testing often is the first that mixes:

  • an present on-line platform with mindfulness coaching and a customized plan for quitting;
    * two armband sensors to detect smoking motions, a know-how that demonstrated greater than 98-percent accuracy in differentiating “lighting up” from different comparable motions. (That compares to 72-percent accuracy in techniques utilizing a single armband);
  • and a customized text-messaging service that reminds the consumer of both their very own plan to stop, or sends video messages that stress the well being and monetary advantages of quitting.

Collaborative effort

The system was conceived, developed and examined over the course of the final yr by a staff of Electrical Engineering and Laptop Science researchers on the Case College of Engineering and a highschool intern in collaboration with a scientific psychologist on the Case Western Reserve College of Medication.

A paper detailing the system and reporting early findings on a bunch of 10 customers was revealed in a July version of Sensible Well being. The researchers mentioned most earlier research have relied on people who smoke self-reporting how usually they smoked, whereas the Case Western Reserve system extra precisely tracked smoking exercise primarily based on the sensors.

“We have been in a position to differentiate between a single movement, which could possibly be confused with consuming or consuming, and a sequence of motions extra clearly linked to the act of smoking a cigarette,” mentioned Ming-Chun Huang, an assistant electrical engineering and pc science professor who led the technical facet of the research.

The collaboration to develop a technology-enhanced, and personalised mobile-smoking cessation system began after a dialog final summer season between Huang, who was in search of a brand new mission for his college students, and Monica Webb Hooper of the Case Complete Most cancers Middle, who was in search of new methods to assist her purchasers break the behavior.

“The sphere of tobacco management has actually adopted cell applied sciences as a result of many individuals will not are available for remedy,” mentioned Webb Hooper, who has been engaged on interventions for practically twenty years.

“We have been serious about translating one in every of our applications right into a video-based cell software, however the movement sensors made this much more superb,” mentioned Webb Hooper, who has prolonged the research to a different 120 smokers–half utilizing this system and a management group utilizing a typical textual content messaging program with out sensors or video messaging.

The habit drawback

Tobacco smoking is chargeable for one in every of each 5 deaths in america, based on the Facilities for Illness Management and Prevention. Different analysis has proven there are greater than 7,000 chemical substances in cigarettes, together with carbon monoxide, hydrogen cyanide and nitrogen oxides in cigarette smoke.

Additional, the Nationwide Most cancers Institute experiences that there are 69 recognized cancer-causing brokers in tobacco smoke.

“Tobacco is the hardest of all addictions to beat and cigarettes are one of many best medicine to turn into addicted to–all it takes is three (cigarettes) for some individuals,” Webb Hooper mentioned. “And, neurologically, it is tougher to stop as a result of we have now extra nicotine receptors within the mind. That is why I am so enthusiastic about this intervention.”


Different contributors to the analysis included PhD pupil Golnous Asaeikheybari; masters’ college students Taiyu Chen and Xiaoliang Zhang; and Nikhil Goel, a Hawken Excessive College pupil who was a part of Ok12 Science Summer season Internship within the lab and helped develop the app interface, Huang mentioned.

Case Western Reserve College is without doubt one of the nation’s main personal analysis establishments. Positioned in Cleveland, we provide a singular mixture of forward-thinking instructional alternatives in an inspiring cultural setting. Our modern school interact in educating and analysis in a collaborative, hands-on setting. Our nationally acknowledged applications embrace arts and sciences, dental medication, engineering, legislation, administration, medication, nursing and social work. About 5,100 undergraduate and 6,200 graduate college students comprise our pupil physique. Go to to see how Case Western Reserve thinks past the potential.
