- Cell Navigation (Table Cell Navigation, Cell-by-Cell Navigation)
- Cell navigation is a method of accessing tabular data non-visually by moving between individual cells using directional commands (up, down, left, right). Rather than reading a table linearly from top-…
- Center of Pressure (COP, Centre of Pressure)
- The point on a surface where the total sum of pressure forces acts, used as a key measure in balance and postural stability assessment. In standing balance evaluation, COP is measured using force plat…
- Central Bank Digital Currency (CBDC)

- Central Vision Loss (Central Scotoma, Macular Vision Loss)
- Loss of vision in the central part of the visual field, typically caused by conditions affecting the macula such as macular degeneration or Stargardt disease. Central vision is responsible for detaile…
- Central Vision Loss (Central Field Loss, Central Scotoma)
