A Performant Web-Based Visualization, Assessment, and Collaboration Tool for Multidimensional Biosignals

Abstract

Biosignal-based research is often multidisciplinary and benefits greatly from multi-site collaboration. This requires appropriate tooling that supports collaboration, is easy to use, and is accessible. However, current software tools do not provide the necessary functionality, usability, and ubiquitous availability. The latter is particularly crucial in environments, such as hospitals, which often restrict users' permissions to install software. This paper introduces a new web-based application for interactive biosignal visualization and assessment. A focus has been placed on performance to allow for handling files of any size. The proposed solution can load local and remote files. It parses data locally on the client, and harmonizes channel labels. The data can then be scored, annotated, pseudonymized and uploaded to a clinical data management system for further analysis. The data and all actions can be interactively shared with a second party. This lowers the barrier to quickly visually examine data, collaborate and make informed decisions.

SLAM – a Thin-Client for Interoperable Annotation and Biomedical Signal Handling

“…Inspired by seminal contributions ten years ago, especially the popular EEG analysis toolbox MNE [16], some efforts were geared towards developing alternative software tools dedicated to this task. One can cite, non-exhaustively, Robin Viewer [17], an open-source, platform-independent, interactive web application, designed for allowing deeplearning paradigms; a clinical EEG research platform [18] designed to allow progressive model construction, including in particular EEG visualization and annotation; copla-editor [19], a web-based visualization, assessment and collaboration tool for multidimensional biosignals; and the time series plug-in of CrowdCurio [20], a generic annotation library with support for EEG data.…”

“…While CrowdCurio [20] claims to support EEG annotation, it is unclear how to run the program [10]. Regarding the other two freely available software platforms, namely Robin's Viewer [17] and copla-editor [19], our contribution shares common properties and purposes, but also differs in various points. Both projects implement an EEG viewer, with the possibility to add annotations in a web-based user interface.…”

“…It can also be used for active learning of a segmentation task, such as artifact detection. [19] is also a web-based EEG visualizer with annotation capabilities. However, these projects do not work solely on a web browser, and do not provide a solution for interoperable annotations.…”

MiCADO-Edge: Towards an Application-level Orchestrator for the Cloud-to-Edge Computing Continuum

“…However existing solutions such as [50,51] suffer from security and privacy failings [49] that make them ill-suited for cloud deployment. Searchable Encryption (SE) is a promising new technology that allows queries on encrypted data in a way that the cloud provider can neither reveal the metadata search term, nor the query result.…”

Cloud apps to‐go: Cloud portability with TOSCA and MiCADO

“…Here, higher levels of data protection are required. Sharing and remote visualization of sleep data is already available, based on the popular open source biomedical data repository xnat and WebRTC 29,30 . However, only transport layer encryption is currently enabled, making it inappropriate for cloud deployment in the current state.…”
