We propose to embed piezoresistive sensing elements into flexible 3D printed objects. These sensing elements are then utilized to recover rich and natural user interactions at runtime. Designing such objects is a challenging and hard problem if attempted manually for all but the simplest geometries and deformations. Our method simultaneously optimizes the internal routing of the sensing elements and computes a mapping from low-level sensor readings to user-specified outputs in order to minimize reconstruction error. We demonstrate the power and flexibility of the approach by designing and fabricating a set of flexible input devices. Our results indicate that the optimization-based design greatly outperforms manual routings in terms of reconstruction accuracy and thus interaction fidelity."}],"quality_controlled":"1","conference":{"name":"CHI: Conference on Human Factors in Computing Systems","location":"San Jose, California, USA","start_date":"2016-05-07","end_date":"2016-05-12"},"date_updated":"2021-01-12T06:49:51Z","publication_status":"published","author":[{"last_name":"Bächer","full_name":"Bächer, Moritz","first_name":"Moritz"},{"last_name":"Hepp","full_name":"Hepp, Benjamin","first_name":"Benjamin"},{"first_name":"Fabrizio","full_name":"Pece, Fabrizio","last_name":"Pece"},{"last_name":"Kry","first_name":"Paul","full_name":"Kry, Paul"},{"id":"49876194-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-6511-9385","last_name":"Bickel","full_name":"Bickel, Bernd","first_name":"Bernd"},{"last_name":"Thomaszewski","full_name":"Thomaszewski, Bernhard","first_name":"Bernhard"},{"last_name":"Hilliges","full_name":"Hilliges, Otmar","first_name":"Otmar"}],"day":"07","publisher":"ACM","title":"DefSense: computational design of customized deformable input devices","doi":"10.1145/2858036.2858354","month":"05","type":"conference","department":[{"_id":"BeBi"}],"publist_id":"5951","status":"public","citation":{"mla":"Bächer, Moritz, et al. <i>DefSense: Computational Design of Customized Deformable Input Devices</i>.
