Analysis is a key part of usability testing where UX practitioners seek to identify usability problems and generate redesign suggestions. Although previous research reported how analysis was conducted, the findings were typically focused on individual analysis or based on a small number of professionals in specific geographic regions. We conducted an online international survey of 279 UX practitioners on their practices and challenges while collaborating during data analysis. We found that UX practitioners were often under time pressure to conduct analysis and adopted three modes of collaboration: independently analyze different portions of the data and then collaborate, collaboratively analyze the session with little or no independent analysis, and independently analyze the same set of data and then collaborate. Moreover, most encountered challenges related to lack of resources, disagreements with colleagues regarding usability problems, and difficulty merging analysis from multiple practitioners. We discuss design implications to better support collaborative data analysis.

We present a compact, field-portable lens-free microscope basedon the principle of spatio-spectral light-field fusion. This is the firsttime a device of this kind has been introduced whereby both superresolutionand signal-to-noise ratio are enhanced via the marriageof synthetic aperture imaging and spectral light-field fusionholography, culminating in a system that is self-contained and fieldportablewhile achieving high resolution, contrast, strong signal fidelity,and ultra-wide field-of-view. The active spatio-spectral illuminationis accomplished in the presented microscope by arranginga series of pulsing LEDs emitting at different spectral wavelengthsin a specific spatial formation. To demonstrate the performance ofthe presented microscope, the system was used to observe twohistology samples: a bovine lung, and corn stem. The imaging resultsdemonstrate the ultra-wide field-of-view advantage of the presentedmicroscope over any other system of its kind, thus enablingfor acquisition of the entire sample without the need for scanning,while producing high-resolution, high-contrast microscopy images(168 megapixels in the current system) that makes it well-suited forscientific and clinical examinations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
