Plug in to your phone and give your loved ones a kiss over the Internet. Kissenger can sense your kiss and transmit realistic kissing sensations to your partner in real time. You can also feel the force on your lips when your partner kisses you back. Share an intimate moment with your friends and families while chatting with them on your phone.

This research looks into sharing intimacy and emotion in digital communication through mediated physical interactions, kissing in particular. It aims to extend our sense of touch by creating an interactive kissing machine that produces dynamic haptic force feedback and other sensory stimuli to transmit realistic kissing sensations over a telecommunication network. The research takes a novel approach to affective communication by constructing a mathematical model of kissing, including the forces, dynamics and bilateral control of the forces to enable remote kissing in a communication system.

A multimodal interactive system for remote kissing interaction is developed. The kissing device is designed as an attachment device for mobile phones, allowing users to kiss each other remotely while having a video chat using their mobile phones. It measures and transmits real-time lip pressure over the Internet. The device consists of force sensors that measure the the contact force between the lip surface of the device and the user’s lips, as well as a linear actuator array to produce accurate force feedback and lip movements during user interaction. A bilateral force controller is used such that both users feel the reflections of their own lip forces as well as the forces from each other. The system also engages the sense of smell by emitting body scents or pheromones from the device.

The system provides a new communication channel for people to share intimacy and affection through remote physical interaction. It engages a wide spectrum of our sensory modalities, including touch and smell, thereby increasing the sense of telepresence and allowing for deep emotional exchanges. While face-to-face interaction is not always available in this increasingly globalised society, this system also offers an effective and intuitive way for parents and grandparents to communicate with young children who have limited language abilities, as well as with people with physical disabilities or communication disorders. The outcome of this research could also make a great impact in the area of robotics and artificial intelligence. The digitisation of kissing provides exciting opportunities for human-robot relationships or even robot-robot relationships. Robots will be able to possess emotional intelligence and learn to understand the emotional meaning and pleasure of kissing, hence establishing intimate and humanistic relationships.

Experience The Internet Kissing

Kissing is the most direct and effective way to express your feelings and love.

With Kissenger, you can kiss your loved ones even when you are physically apart.

How It Work

High precision force sensors are embedded under the silicon lip to measure the dynamic forces at different parts of your lips during a kiss. The device sends this data to your phone, which transmits it to your partner over the Internet in real time. Miniature linear actuators are used to reproduce these forces on your partner’s lips, creating a realistic kissing sensation. Kissenger provides a two-way interaction just like in a real kiss. You can also feel your partner’s kiss on your lips when they kiss you back.
