Decades of rapid advancement in semiconductor technology has enabled computing in cheap, small form factor everyday devices. Human users are now submerged in a sea of computers, with which they are constantly interacting. User interaction with the surrounding environment is one of the key aspects of ubiquitous computing. Communication between devices during a touch-based interaction will significantly enhance the effect of a touch event and open up new interaction modalities in human–computer interaction (HCI). The standard method of achieving this is through coupling touch (Figure 2(a)) and communication (Figure 2(b)) separately. That can be done by utilizing a touch sensor (example: capacitive touch sensor) along with some wireless communication protocol such as Bluetooth, Near Field Communication (NFC) (Figure 2(c)). These protocols use radio waves, utilizing air as the communication medium. Wireless radio wave communication suffers from the problem of security and selectivity, as the signal gets transmitted through air medium and is available to any device within a certain range. As a result, information may get communicated when the devices are in close proximity, even before touch. Thus, communication strictly during a touch event i a secure and selective manner is difficult to achieve with radio communication.
