Material and production research to create a touchscreen accessory
As an extension of reality pepper’s ghost effect has been used in theatre productions. The use of this phenomenon based on reflection has been growing with the number of screens around us. In cooperation with the Berlin based Fraunhofer CeRRI options to add interaction to this normally static „hologram“-experience were explored. Expanding the interactivity of touchscreens into the third dimension.
An exploration of materials such as reflective and bendable foils, conductive pastes and coatings, and different production techniques with partners around Germany made JUWL Touch possible.
JUWL now is an independent business offering media solutions for hologram experiences.

A symmetric but non-isosceles triangle forms the basis for the touch recognition based on three pads which are in contact with the touchscreen.
Material and geometry tests to register position and orientation on capacitive touchscreens. A variety of materials and configurations were tested, from custom silicone mixtures infused with graphite or silver to coated PCBs to reduce friction and scratches on the glass of the touchscreen.
To add to JUWL's inherent capacity a conductive connection to the users hand needed to be established to allow for continuous tracking of the accessories position and orientation thus enabling smooth interaction.
