WASHINGTON, Jan. 8 (Xinhua) -- Good news for people with bad memory. HoloLens, a pair of augmented reality (AR) glasses developed and manufactured by Microsoft, can help people find and track objects such as car keys.

HoloLens works by "remembering" what things look like when the person wearing the glasses holds an item up to tiny cameras fitted into the glasses and orders: "Track this object."

Then, whenever that item is in view, the glasses record their locations. When people asked "where are my keys," a tiny screen in the corner of the lens will pop up and suggest where they last saw the keys.

The new device is expected to make life easier for those having trouble finding their everyday objects, especially for the elderly and patients suffering from Alzheimer's disease.

"Assistive technology like these glasses can enable people with dementia to live independently for longer, reduce stress and enhance their quality of life," Alzheimer's Society head of policy George McNamara told the Daily Mail.

However, to some people, the idea of locating lost things by wearing the AR glasses does not make a lot of sense, as it is inefficient and inconvenient to always wear the smartglasses.

If you drop your keys somewhere without looking at them, the system might not register the new location, and thus could not find them. It is also possible that you even forget about where you have dropped your HoloLens.

But according to tech news website the Verge, what's really interesting about HoloLens isn't the idea of tracking an object in an Internet connected household. What matters more is the smartglasses learning what items matter to you and choosing what to follow, before you worry about losing something, it said.
