Indikatorji svetlobe in barve so naprave, ki slepim pomagajo pri prepoznavanju barv in svetlobe. S pomočjo točno določene frekvence senzor prepozna barvo in jo v govorni obliki sporoči slepi osebi.

Indikatorji tekočine pa s pomočjo spojenih kontaktov, ki jih sproži nivo tekočine, slepim nakažejo, kdaj je posoda oz. kozarec napolnjen do določenega nivoja. 

Slika prikazuje Lumi test, ki slepim sporoča prisotnost svetlobe in njeno intenzivnost. Na ta način ugotovimo, ali je zunaj mrak, oblačen ali sončen dan.

Slika prikazuje napravo Colorino, ki z govorno indikacijo sporoča barvo različnih predmetov. Na voljo je tudi v slovenščini.
