Infrared light is the most common choice for illumination of the eye in current eye trackers, usually produced via IR light-emitting diodes (LEDs). This chapter provides an overview of the potential hazards of over-exposure to infrared light, the safety standards currently in place, configurations and lighting conditions employed by various eye tracking systems, the basics of measurement of IR lig
This report was initiated and conducted as input to the discussions based on the “Vision 2015” document for the Nordic Swan that explicitly states a wish to find ways to make use of ecolabelling in the green public procurement (GPP) setting. In 2014, the Directive (2004/18/EG) on public procurement was revised and replaced by Directive (2014/24/EU). Some of the restrictions in using ecolabelling i
Popular Abstract in Swedish Tarot är ett exempel på new age i praktiken. Tarotkorten har dock anor långt ned i den medeltida världen. Författaren återkommer till att new age erbjuder alternativ: kritik mot rationalitet, modernitet och ekonomisk utveckling. "Deltagarna är generellt sett skeptiska till det etablerade i samhället: medicinskt, politiskt och vetenskapligt. De vill bortse från det instiIn the course of my dissertation work, I have sought knowledge about what New Age is, contains, and conveys by looking at practice and rhetoric, how the participants act and reason regarding their commitment, as well as how the contents of the field is discussed. I have put an emphasis on the small details: the objects, the rituals, and the narrating. Using the tarot cards as a starting point, the
Popular Abstract in Swedish En semiautomatiskt uppgiftsorienterad (eng. task oriented) systemstruktur har utvecklats och testats i en svetsapplikation. I normal industriell robotprogrammering skapas verktygsvägar varefter tillverkningsprocessen baseras på den väg som fastslagits. Här föreslås istället en processorienterad metod. Det är naturligt att fokusera på processen eftersom verktygsvägen egeA semi-automatic task oriented system structure has been developed and tested on an arc welding application. In normal industrial robot programming, the path is created and the process is based upon the decided path. Here a process-oriented method is proposed instead. It is natural to focus on the process, since the path is in reality a result of process needs. Another benefit of choosing process
A great need exists in many fields of eye-tracking research for a robust and general method for scanpath comparisons. Current measures either quantize scanpaths in space (string editing measures like the Levenshtein distance) or in time (measures based on attention maps). This paper proposes a new pairwise scanpath similarity measure. Unlike previous measures that either use AOI sequences or forgo
