With a relatively simple software update, your smartwatch could be even smarter.

Researchers have developed a proof-of-concept that can take any smartwatch and make it capable of telling what object (which must be vibrating in your hand) you are currently holding.

This is done by changing how often the watch takes motion readings from 100 times a second to 4000 times a second. That change in the frequency of readings enables the watch to use the vibrations of the object and tell what you are holding.

From dustbusters to electric toothbrushes, the possibilities are endless.

Imagine picking up your pill bottle, giving it a shake, and your watch tells you which medication it is and how many pills you have left. Potentially, with the right application, your watch could also automatically request refills when you are running low.

Another possibility for this technology could be as simple as little everyday reminders. In the morning when you pour milk on your cereal, your watch could recognize that you are running low on milk. Later that day, when it picks up on the vibrations of you pushing a shopping cart, it sends you a friendly reminder to pick up more milk before you leave the store.

Having technological advancements like this are always great for numerous reasons. Smartwatches like these could be a great help to the elderly and the blind. And a giant convenience to the everyday consumer by helping to alleviate little stressors like forgetting to buy more milk.
