- In their daily lives, people use more than one sense to perceive and interpret their environment. Likewise, audio-visual interfaces can support human data analysts better than interfaces relying on just one sense. While the research communities of sonification and visualization have both carried out extensive research on the auditory and visual representation of data, comparatively little is known about their systematic and complementary combination for data analysis. After two workshops at Audio Mostly 2021 and IEEE VIS, this 3rd workshop on audio-visual analytics continues building a community of researchers interested in combining visualization and sonification.

- We survey the space of three-dimensional mobile visualizations, that is, 3D abstract or spatial data on mobile 2D displays, or mobile head-mount augmented- and virtual-reality displays. As a playful “case study” we use a scenario from the film “Aliens,” in which a mobile, small-screen visualization device is used to track the movements of enemy aliens around a group of space marines. In this scenario, the marines are overrun by aliens in the ceiling, as their device fails to show them the height dimension of the space around them. We use this example to illustrate how different mobile and 3D interaction techniques could have prevented the misunderstanding in the movie, using both hypothetical descriptions of the improved movie action and a scientific discussion of these scenarios and their implications

Parallel Chords: an audio-visual analytics design for parallel coordinates
- 2024

- One of the commonly used visualization techniques for multivariate data is the parallel coordinates plot. It provides users with a visual overview of multivariate data and the possibility to interactively explore it. While pattern recognition is a strength of the human visual system, it is also a strength of the auditory system. Inspired by the integration of the visual and auditory perception in everyday life, we introduce an audio-visual analytics design named Parallel Chords combining both visual and auditory displays. Parallel Chords lets users explore multivariate data using both visualization and sonification through the interaction with the axes of a parallel coordinates plot. To illustrate the potential of the design, we present (1) prototypical data patterns where the sonification helps with the identification of correlations, clusters, and outliers, (2) a usage scenario showing the sonification of data from non-adjacent axes, and (3) a controlled experiment on the sensitivity thresholds of participants when distinguishing the strength of correlations. During this controlled experiment, 35 participants used three different display types, the visualization, the sonification, and the combination of these, to identify the strongest out of three correlations. The results show that all three display types enabled the participants to identify the strongest correlation — with visualization resulting in the best sensitivity. The sonification resulted in sensitivities that were independent from the type of displayed correlation, and the combination resulted in increased enjoyability during usage.

Integrating Sonification and Visualization – But Why?
- 2024
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The research communities studying visualization and sonification share exceptionally similar goals, essentially aiming to make data interpretable to humans. One community uses visual representations, while the other employs auditory (nonspeech) repre- sentations of data. Although the two communities have much in common, they developed mostly in parallel, with only compara- tively few examples of integrated audiovisual data analysis idioms presented so far. This panel brings together researchers from both the fields of visualization and sonification to collectively discuss the question: ‘Integrating Sonification and Visualization – but why?’ In the panel discussion, we will tackle this question along two main hypotheses: Combining the modalities to (1) increase the “bandwidth from data to brain,” or (2) to increase a user’s personal engagement during the data analysis process. On the one hand, designers might aim to communicate more data in less time or gain more and more complex insights from the data by using a multi-modal display. This argument follows an understanding that two senses should be capable of processing more information than “just” one. On the other hand, sometimes, a more engaged analysis of the represented data is desirable. Engagement with data visualization stands as a crucial topic in numerous contexts within our field, encouraging “deeper” thinking by expert analysts, readers of data journalism articles, and students in educational settings. We hypothesize that integrating visualization with sonification holds the potential to enhance user engagement during analysis. Through the panel discussion, we want to delve into the spectrum between aiming for bandwidth and engagement, seeking to understand the opportunities and challenges of integrating sonification and visualization.

Hyperfine interaction limits polarization entanglement of photons from semiconductor quantum dots
- 2023
-
Ingår i: Physical Review B. - 2469-9950 .- 2469-9969. ; 108:8

Tidskriftsartikel (refereegranskat)abstract
- Excitons in quantum dots are excellent sources of polarization-entangled photon pairs, but a quantitative understanding of their interaction with the nuclear spin bath is still missing. Here we investigate the role of hyperfine energy shifts using experimentally accessible parameters and derive an upper limit to the achievable entanglement fidelity. Our results are consistent with all available literature, indicate that spin noise is often the dominant process limiting the entanglement in InGaAs quantum dots, and suggest routes to alleviate its effect.
