This paper proposes Attractive Flicker, a novel technique for visual guidance in dynamic narrative visualizations.

However, finding a visual feature to enhance for the focus to pop out from its context in a large dynamic scene, while leading to minimal visual deformation and subjective disturbance, is challenging. Waldner, Manuela Le Muzic, Mathieu Bernhard, Matthias Purgathofer, Werner Viola, Ivanįocus+context techniques provide visual guidance in visualizations by giving strong visual prominence to elements of interest while the context is suppressed. Secondly, light spectrum flicker response measurements of different lampĪttractive Flicker-Guiding Attention in Dynamic Narrative Visualizations. These lamp flicker response models are implemented into the improved flickermeter models, which can provide the better match between the output and customer complaints for specific lamp types. The lamp flicker response models are studied and tested by using the Matlab/System Identification Toolbox. The five lamp types flicker response models are derived by using linear system identification methods based on the results of the flicker response (illuminance flicker response) measurements. To analyze and evaluate the measured data, Fourier analysis is done and different filter types are tested using Matlab. Flicker response (illuminance flicker response) measurements of five lamp types (the incandescent lamp, fluorescent lamp, halogen lamp, energy saving lamp and LED lamp) have been made in the Power Quality Lab of TUE. This is due to the fact that the UIE/IEC flickermeter model is built by only considering the incandescent lamp as the reference lamp. The statistical measurement database shows that the average long-term flicker indicator P) that correlate well with the customer sensitivity for different lamp types. In the Netherlands, the grid operators' database of complaints on voltage quality shows that almost 60% of all complaints are about flicker.

It is the noticeable light intensity variation of a lamp caused by rapid voltage fluctuations in the electrical power system.
