Note: Sound device in which a photoelectric cell is used to scan a text, which then produces electric signals that are converted into audible sound. The instrument today is generally used to enable the blind to read, although the device had its origins with the inventions of Austrian artist and Dadaist Raoul Hausmann in the 1920s, who was preoccupied with unifying the senses, and changing light into sound. It was patented in 1935 as a "calculating device".

Additional Notes: |
|
| Dutch ..... Instrumenten waarin met behulp van een foto-elektrische cel een tekst wordt gescand en omgezet in elektrische signalen die vervolgens worden weergegeven als geluid. Het apparaat wordt tegenwoordig voornamelijk gebruikt om blinden in staat te stellen te lezen, maar het had in de jaren 20 van de 20ste eeuw zijn oorsprong in de uitvindingen van de Oostenrijkse kunstenaar en dadaïst Raoul Hausmann, die zich bezighield met het verenigen van de zintuigen en het veranderen van licht in geluid. De optofoon werd in 1935 geoctrooieerd als rekenmachine. |
