Compare up to 10 devices across categories. Keep the purpose and the source beside the numbers.
Lowest recorded store prices take priority over announced or launch prices, within the selected source market. Currencies use the dated EUR reference rates. Deposits and recurring charges are excluded from price order; missing prices stay last. Original price records remain visible.
Hand and arm gesture control of electronic music
Keep in mind Photograph records the physical instrument at STEIM in2006; it is not presented as the original1984 revision.
Surface muscle signals as musical control input
Keep in mind Wearable electrodes and interface require the external rack processor; not a self-contained wearable.

Battery claims use different conditions and are not a controlled benchmark. “Not verified” is an evidence gap, not a missing feature. Prices are dated regional snapshots. Deposits, bundles and historical launch prices are labelled. Brightness measurement methods and battery workloads vary by manufacturer.
