--- res: bibo_abstract: - We present a novel optimization-based algorithm for the design and fabrication of customized, deformable input devices, capable of continuously sensing their deformation. 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.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Moritz foaf_name: Bächer, Moritz foaf_surname: Bächer - foaf_Person: foaf_givenName: Benjamin foaf_name: Hepp, Benjamin foaf_surname: Hepp - foaf_Person: foaf_givenName: Fabrizio foaf_name: Pece, Fabrizio foaf_surname: Pece - foaf_Person: foaf_givenName: Paul foaf_name: Kry, Paul foaf_surname: Kry - foaf_Person: foaf_givenName: Bernd foaf_name: Bickel, Bernd foaf_surname: Bickel foaf_workInfoHomepage: http://www.librecat.org/personId=49876194-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0001-6511-9385 - foaf_Person: foaf_givenName: Bernhard foaf_name: Thomaszewski, Bernhard foaf_surname: Thomaszewski - foaf_Person: foaf_givenName: Otmar foaf_name: Hilliges, Otmar foaf_surname: Hilliges bibo_doi: 10.1145/2858036.2858354 dct_date: 2016^xs_gYear dct_language: eng dct_publisher: ACM@ dct_title: 'DefSense: computational design of customized deformable input devices@' ...
