Hi all, We will HCI meeting this Tuesday Oct. 20 12:30pm-2pm. We will have three DGP members to present this time. They are�Varun Permumal, Michael Glueck, and Haijun Xia. They each will give a practice talk about their upcoming conference talk (UIST'15,�VAST'15 TVCG). Please attend and give them feedback. Lunch will be provided.� The titles and abstracts of their presentations are listed below. Speaker: Varun Permumal Title: Printem: Instant Printed Cirucit Boards with Standard Office Printers and Inks Abstract:�Printem film, a novel method for the fabrication of Printed Circuit Boards (PCBs) for small batch/prototyping use, is presented. Printem film enables a standard office inkjet or laser printer, using standard inks, to produce a PCB: the user prints a negative of the PCB onto the film, exposes it to UV or sunlight, and then tears-away the unneeded portion of the film, leaving-behind a copper PCB. PCBs produced with Printem film are as conductive as PCBs created using standard industrial methods. Herein, the composition of Printem film is described, and advantages of various materials discussed. Sample applications are also described, each of which demonstrates some unique advantage of Printem film over current prototyping methods: copper-quality conductivity, flexibility, the ability to be cut with a pair of scissors, and the ability to be mounted to a rigid backplane to provide a more standard rigidity for the resulting PCB. Additionally, related work is described in detail, and future applications of Printem-like technology are described.
� Speaker: Michael Glueck Title:�PhenoBlocks: Phenotype Comparison Visualizations Abstract:�The differential diagnosis of hereditary disorders is a challenging task for clinicians due to the heterogeneity of phenotypes that can be observed in patients. Existing clinical tools are often text-based and do not emphasize consistency, completeness, or granularity of phenotype reporting. This can impede clinical diagnosis and limit their utility to genetics researchers. Herein, we present PhenoBlocks, a novel visual analytics tool that supports the comparison of phenotypes between patients, or between a patient and the hallmark features of a disorder. An informal evaluation of PhenoBlocks with expert clinicians suggested that the visualization effectively guides the process of differential diagnosis and could reinforce the importance of complete, granular phenotypic reporting. � Speaker: Haijun Xia Title:�NanoStylus: Enhancing Input on Ultra-Small Display with a Finger-Mounted Stylus Abstract:�Due to their limited input area, ultra-small devices, such as smartwatches, are even more prone to occlusion or the fat finger problem, than their larger counterparts, such as smart phones, tablets, and tabletop displays. We present NanoStylus – a finger-mounted fine-tip stylus that enables fast and accurate pointing on a smartwatch with almost no occlusion. The NanoStylus is built from the circuitry of an active capacitive stylus, and mounted within a custom 3D-printed thimble-shaped housing unit. A sensor strip is mounted on each side of the device to enable additional gestures. A user study shows that NanoStylus reduces error rate by 80%, compared to traditional touch interaction and by 45%, compared to a traditional stylus. This high precision pointing capability, coupled with the implemented gesture sensing, gives us the opportunity to explore a rich set of interactive applications on a smartwatch form factor. � Thanks for your attention, Mingming
