Capacitive touch-sensing technology won’t be limited to smart devices (phones/tablets) and monitors as a group of researchers from Carnegie Mellon University and Disney Research plan to bring it to everyday objects and surfaces. To do this, the team designed what they call ‘Touché,’ which brings interactive capacitive-touch sensing to everything from tables and doorknobs. Where typical touch-capacitive screens use a single frequency to sense a predefined touch event, Touché uses multiple frequencies, known as Swept Frequency Capacitive Sensing, which can enable objects to sense complex combinations of touches or even gestures.
For example; a door would unlock itself based on how you grabbed the doorknob, or a table could sense and advise you on your posture based on how you’re leaning against it. The team states that this could be done by using just one sensing-electrode and can even be implemented on the human body making ‘you’ an input device. Another test showed that SFCS could detect a person’s body gestures using electrodes which could be used to interact with smartphones or other devices. An example could be silencing your phones ringer by simply placing a finger on your lips or starting your car just by grabbing the door handle. The possibilities are endless , and the researchers state that Touché could be immediately implemented in creating new ways of interaction with our environment.
