Note: Bubble size represents cost (relative, larger = more expensive). Spatial resolution increases bottom-to-top, temporal resolution increases left-to-right. Hover over bubbles to see detailed tooltips with all attributes. Checkboxes above let you filter modality types by category.

About This Visualization

This interactive web application maps different physiological and sensing modalities—like EEG, ECG, fNIRS, audio, and video—across two critical dimensions: temporal and spatial resolution. Each modality is represented as a bubble, with size indicating relative cost. You can toggle the visibility of categories such as neuro, cardio, visual, etc., to focus your exploration. It's a hands-on way to learn the trade-offs in signal fidelity, ease of use, and hardware expense.

Fun Review: Think of this chart as a cocktail party of sensors. EEG high-density shows up overqualified and overdressed, while GSR keeps things casual. Some guests crowd the same corner, like audio and video modalities clustering low on the spatial axis—but that’s what makes this visual chaotic in the best kind of way. It’s data-driven storytelling with orbs and color. And it works.
