Wearable glasses are a tricky business. Just ask Google, whose Google Glass was slammed widely as ugly and intrusive. This has not stopped Germany's University of Passau from pursuing wearable glasses through the WISEglass project. The initiative has now produced a pair of spectacles that are, for now, referred to as Diet Eyeglasses.

In a new paper, researchers outline how the glasses can help wearers with their diet. The device uses electromyography to monitor chewing. Data gathered can be utilized to track food intake. Researchers told Digital Trends that they use machine learning to categorize different foods, differentiating between crunchy and chewy items, for example. Over time, researchers hope the technology can evolve to replace manual logging of food intake.

The prototype of the glasses was made using 3D printing. It is unclear whether this kind of product could be a big seller. Glasses are usually an item of necessity that have become fashionable, too. Other wearable makers are dealing with the convergence of fashion and tech, but the process is not smooth. If wearable glasses do become popular, however, some people might want a pair that does more than simply monitor their food intake. This feature might make it into other, more full-featured smart glasses.
