Created by Florian Born, Modulares Interface B.A. is a physical interface for iPad comprised of knobs, buttons and sliders to provide precision and haptic feedback when operating a digital interface.
Multi-touch devices like the iPad have become more and more popular over the last couple of years. Nowadays they are not only used for browsing and sending e-mails, but also as a medium for new fields of applications. One particular thing of multi-touch devices is in need of improvement: It is the lack of haptic feedback, which makes it difficult to set parameters precisely.
Regarding to this problem the project has been developed to provide a variety of physical controllers. These controllers expand the usage of a touch device with a haptic feedback while adjusting parameters. By using magnets, the different controllers can easily be arranged onto the iPad. A modular interface appears, which uses a given device just like the iPad.
The system contains three different parts:
– The physical controllers (button, slider and knob), made out of conductive aluminium to pass on the electrical discharge of the human skin.
– A frame, made out of aluminium and plastic, in which the iPad is inserted. The edge of the frame has embedded magnets, making it possible to position the controller precisely and easily.
– The software, running as an app on the iPad. It organizes the control elements and sends the parameters to the corresponding software, which is controlled by the modular interface.
“Recent research proposes augmenting capacitive touch pads with tangible objects, enabling a new generation of mobile applications enhanced with tangible objects, such as game pieces and tangible controllers. In this paper, we extend the concept to capacitive tangibles consisting of multiple parts, such as stackable gaming pieces and tangible widgets with moving parts. We achieve this using a system of wires and connectors inside each block that causes the capacitance of the bottom-most block to reflect the entire assembly. We demonstrate three types of tangibles, called CapStones, Zebra Dials and Zebra Sliders that work with current consumer hardware and investigate what designs may become possible as touchscreen hardware evolves.”
