“…In capacitive touch devices, touch inputs can be invoked through a conductive material such as metal [39,40], conductive rubber [18,41], or ink [10,38], in addition to finger contact. An emerging stream of research has focused on using physical objects with conductive materials to enrich touch devices interactions.…”

“…The ability of capacitive touch devices to impart interactivity to physical objects with conductive materials, without requiring additional active sensors or batteries, has led to several applications that extend touch devices for interactions. However, most of the conventional physical interfaces focused only on the occurrence of tapping at specific positions [41] or touch gestures in predetermined directions [3,20] (e.g., up and down scrolling). As a result, the degree of freedom of input is limited.…”

We propose a 3D-printed interface, CAPath, in which conductive contact points are in a grid layout. This structure allows not only specific inputs (e.g., scrolling or pinching) but also general 2D inputs and gestures that fully leverage the "touch surface. " We provide the requirements to fabricate the interface and implement a designing system to generate 3D objects in the conductive grid structure. The CAPath interface can be utilized in the uniquely shaped interfaces and opens up further application fields that cannot currently be accessed with existing passive touch extensions. Our contributions also include an evaluation for the recognition accuracy of the touch operations with the implemented interfaces. The results show that our technique is promising to fabricate customizable touch-sensitive interactive objects. CCS Concepts: • Human-centered computing → Human computer interaction (HCI).

“…Multi-touch capacitive screens can also be used to transform tokens into interactive elements. The approach consists of building tokens that create a conductive circuit between users' fingers and the capacitive surface through the tokens' feet, that are in contact with the surface (e.g., [7,16,28]). As soon as the user touches the token, the feet become grounded and generate a drop in capacitance similar to a multi-touch pattern.…”

TouchTokens were introduced recently as a means to design lowcost tangible interfaces. The technique consists in recognizing multitouch patterns associated with specific tokens, and works on any touch-sensitive surface, with passive tokens that can be made out of any material. TouchTokens have so far been limited to a few basic geometrical shapes only, which puts a significant practical limit to how tailored token sets can be. In this article, we introduce TouchTokenBuilder and TouchTokenTracker that, taken together, aim at facilitating the development of tailor-made tangible interfaces. TouchTokenBuilder is an application that assists interface designers in creating token sets using a simple direct-manipulation interface. TouchTokenTracker is a library that enables tracking the tokens' full geometry. We report on experiments with those tools, showing the strengths and limitations of tangible interfaces with passive tokens.

“…As soon as the user touches an object, its feet become grounded and generate a drop in capacitance similar to a multi-touch pattern. Physical widgets [33] rely on this technique, as do physical button pads that can be clipped to the edges of a device [55], or more advanced objects that feature moving parts [17,28] or that can be stacked [17]. Designing conductive tokens is challenging: the feet must be positioned carefully and the circuit must be stable so that the generated touch pattern can be recognized consistently.…”

“…Designing conductive tokens is challenging: the feet must be positioned carefully and the circuit must be stable so that the generated touch pattern can be recognized consistently. As capacitive screens have been designed for human fingers, properties such as the feet's minimal size and the minimal distance between two feet, which depend on the device, must be carefully chosen [55].…”
