![]() ![]() The data show RB can be obtained under conditions in which memory problems are minimal and where perceptual sensitivity is assessed independently of biases. Results of five experiments show that perceptual sensitivity is strikingly and significantly reduced in the RB condition relative to both baseline control conditions. In control treatments, the precue was either an unrelated word or a dummy (XXXX). In the critical condition for RB a precue of the post-target word was provided prior to the target stimulus (identity precue), so that the required judgement amounted to whether the target did or did not repeat the precue word. Confidence ratings permitted use of signal detection methods to assess sensitivity and bias effects. Subjects made only a single judgement about whether one masked target word was the same or different than a post-target probe. "single-frame" paradigm introduced by Johnston and Hale (1984) in which memory demands are minimal. ![]() The standard rapid serial visual presentation (RSVP) paradigm used in most RB studies is, indeed, open to such objections. Recently, however, researchers have attributed RB to post-perceptual processes such as memory retrieval and/or reporting biases. The phenomenon of repetition blindness (RB) may reveal a new limitation on human perceptual processing. ![]() Together this work characterizes how designers can use area touches in watch UIs, which area touches are most appropriate and how users respond to this interaction style. We report generally positive user reactions to these demonstrators: the area touch interactions were perceived as quick, convenient and easy to learn and remember. Finally, we describe three demonstration applications that instantiate ideas from the workshop and deploy the most reliably and rapidly produced area touches. Secondly, we describe a sensor unit and study that captured user performance with 31 area touches and contrasted this against standard targeting performance. Firstly, we present four design themes that emerged from an ideation workshop in which five designers proposed concepts for smartwatch. We explore how touch contact areas, such as lines generated by flat fingers, can be used to increase input expressivity in these diminutive systems in three ways. Smartwatches are emerging device category that feature highly limited input and display surfaces. Gauge Capability Ratio, study variance to tolerance ratio, et al.) of 11% and resolving up to 74 distinct categories when measuring these features. ![]() The Gauge R&R studies effectively provided management with quantitative measures for determining whether a candidate system was adequate for measuring the critical feature of interest, which was a 10 ± 2 micron difference between adjacent step heights, and as a result, Accumold has purchased a new multi-sensor system capable of achieving a precision to tolerance ratio (a.k.a. The ANOVA-based "Gauge R&R" (Repeatability and Reproducibility) study was employed as the main analytical tool for determining the efficacy of a potential measurement system factors like potential for automation, ease of use and programming, and shop floor robustness were considered. Many measurement technologies (including confocal and dynamic range lasers, scanning electron microscopes, white light interferometers, and precision video) from manufacturers around the world were explored. As engineering tolerances approach the submicron range and customer demands for statistically verified quality levels increase, Accumold, a highly specialized, high-tech manufacturer of injection molded lead-frame and small- and micro-scale plastic parts, has realized a critical need for an improved measurement system. ![]()
