## What is Trail it?

Trail it er et spil som træner dit syn og din koncentrationsevne. I spillet forbinder man cirkler i rækkefølgen "1-2-3-4" eller "1-A-2-B" der er fordelt i tilfældige mønstre på skærmen. Trail it er en digitalisering af Trail Making Test, som er en neuropsykologisk test man bruger til at diagnosticere og træne visuel negligering. Dette gør Trail it ved at måle din reaktionstid på henholdsvis højre og venstre side af skærmen.

Trail it er udviklet af studerende ved Aalborg Universitet, som forsker i digitale apps til brug i rehabilitering og derhjemme.

Det anbefales at spille spillet på IPad.
