Kurzbeschreibung (Abstract)

In this paper the Linoc prototyping toolkit is presented. It is a sensor toolkit that focuses on fast prototypingof sensor systems, especially on capacitive ones. The toolkit is built around two capacitive and two ElectricPotential Sensing (EPS) groups providing unobtrusive proximity detection in the field of Human ComputerInterface (HCI). The toolkits focus lies on its usability and connectivity in order to be adapted in future researchand novel use cases. A common obstacle in the beginning of a project is the time required to familiarize withpresent tools and systems, before the actual project can be attended to. Another obstacle while tackling newtasks is the actual physical connection of sensors to the processing unit. This situation can be even worsedue to dependencies on previous work, most of the times not fully documented and missing knowledge evenif the the original designer is involved. Good toolkits can help to overcome this problem by providing alayer of abstraction and allowing to work on a higher level. If the toolkit however requires too much time tofamiliarize or behaves too restrictive, its goal has been missed and no benefits are generated. To assess thequality of the Linoc prototyping toolkit, it was evaluated in terms of three different aspects: demonstration,usage and technical performance. The usage study found good reception, a fast learning curve and an interestto use the toolkit in the future. Technical benchmarks for the capacitive sensors show a detectable range equalto its predecessors and several operational prototypes prove that the toolkit can actually be used in projects.
