Straw-like User Interface developed by Inami Laboratory at Keio University "allows users to virtually experience the sensations of drinking. Such sensations are created by referencing sample data of actual pressures, vibrations, and sounds produced by drinking from an ordinary straw attached to the system."
"The system transmits pressure changes to the straw, which applies vibrations to the mouth. The pressure changes are created by a valve in the interface. If the valve is closed, the pressure increases. If the valve is open, the pressure decreases. Also, when the speaker inside the interface vibrates, the straw attached to it receives the vibration and transmist it to the lips."
I can see this being used in game experiences where the user interacts with while waiting at a bar or restaurant for example. Or help the elderly and physically challenged to experience and sense perception that they are unable to do. Or possibly a gamified water bottle that you can play with and helps you hydrated at the same time.
