Vessyl uses a small, proprietary sensor located inside the glass-lined cup to detect what kind of liquid it's holding and how fast the user is drinking. It tracks a number of parameters -- from standard nutritional information to the brand of the drink -- and displays the data using a companion app or via an embedded display on the side of the cup.
Mark One, Vessyl's creators, say the 13-ounce cup can handle any kind of liquid that people normally drink. It can even analyze thicker liquids, like yogurt and smoothies.
A built-in battery will power the cup's sensor and display for between five and seven days. The battery can be topped up in approximately one hour using an inductive charging pad -- which Mark One calls a "saucer" -- that plugs into a wall socket.
Vessyl is available now for pre-order directly from the company's website at a discounted cost of $99. The cups are expected to ship early next year, at which time the price will increase to $199.
