Capacitive Fingerprinting by
Capacitive Fingerprinting is a new sensing approach to differentiate between multiple users engaging with touch screens and other interactive surfaces. Although currently touchscreens can differentiate multiple points of contact, they are not able to differentiate who is touching the device. In Capacitive Fingerprinting we consider how the electrical properties of human bodies and their attire can be used to support user differentiation on touchscreens. The technique is based on Touche technology that we proposed earlier and which measures the impedance of a user to the environment (i.e., ground) across a range of AC frequencies. Different people have different bone densities and muscle mass, wear different footwear, and so on. Therefore, different people will have different impedance profiles, which allows for touch events, including multitouch gestures, to be attributed to a particular user. This has many important implications for interactive design in gaming, collaborative and security applications." |

Revel: Programming the Sense of Touch by
REVEL is a new wearable tactile technology that modifies the user's tactile perception of the physical world. It can add a layer of artificial tactile texture to almost any surface or object, with very little if any instrumentation of the environment. As a result, REVEL can provide dynamic tactile sensations on touch screens as well as furniture, walls, wooden and plastic objects, and even human skin. REVEL is based on Reverse Electrovibration. It injects a weak electrical signal into anywhere on the user's body, creating an oscillating electrical field around the user's skin. When sliding his or her fingers on a surface of the object, the user perceives highly distinctive tactile textures that augment the physical object. Varying the properties of the signal provides a wide range of tactile sensations. |

Touché: Enhancing Touch Interaction on Humans, Screens, Liquids, and Everyday Objects by DisneyResearchHub
Touché proposes a novel Swept Frequency Capacitive Sensing technique that can not only detect a touch event, but also recognize complex configurations of the human hands and body. Such contextual information significantly enhances touch interaction in a broad range of applications, from conventional touchscreens to unique contexts and materials. For example, in our explorations we add touch and gesture sensitivity to the human body and liquids. We demonstrate the rich capabilities of Touché with five example setups from different application domains and conduct experimental studies that show gesture classification accuracies of 99% are achievable with our technology. |
