ChargerPro: Hey! For screen readers, keep the curve data in a plain‑text table – voltage and time pairs that can be read line by line. Add a live‑update text summary like “Current voltage: 4.20 V, target 4.20 V reached at 00:12:34”. Use ARIA labels on the canvas so the reader knows it’s a graph and can skip to the numbers if it wants. Make the colors high‑contrast and offer a grayscale mode for color‑blind users. If you need a visual curve, let the user zoom with a slider; each zoom level should update the text table. Add optional audio cues for when the charger hits a key threshold, and keep the numeric data precise so you don’t lose that calibration edge. That way, the UI stays crisp for the tech‑savvy and friendly for the accessible crowd.
