You can click through various color blindness conditions and see in the video output a simulation of the way a person with that condition might see the world. You can turn the device into landscape mode too, which will give you the same options, but with a layout fit for that mode (with the video on the left, and the list of options on the right).
Point the device’s back camera to an object. The app will classify and isolate the colors in the video into red-ish colors and green-ish ones. The box on the left will have the video of the parts which are red-ish in color, and the one on the right will be for green-ish colors.
In this way, a person who is not sure whether an object is red or green, will get to know for sure which of the two color categories it falls into. If the object is neither red-ish in color nor green-ish, it simply won’t appear in either of the two boxes.
To magnify, extend the slider all the way to the right. The magnifier allows you to zoom all the way upto the maximum limit that the mobile phone camera allows – but then you can magnify even further using pinch-and-zoom. This way, you can combine optical and digital zoom to get a boost in magnification, and just this feature alone makes it instantly better than every other magnifier native app out there.
To enable the torch (but seeing in low-light conditions), tap on the icon to the right of the slider which looks like a torch. Tapping it again would disable it.
To freeze the camera, tap on the button which says ‘Freeze Caemra’. This will give you a snapshot image of the currently focussed camera outoput, so that you can take more time to see the image and not need to keep the phone physically pointed at the object. Once you’re done, and need to go back to the live camera output, click on the button which says ‘Return to live camera’.
The icon which looks a bit like a book or tablet device is for ‘reading mode’. For text, (and especially handwriting) people with low-vision sometimes appreciate a mode where the colors could be inverted (so that most text, which is light background with dark text becomes dark background with light text – which is easier on the eyes for long reading) and the contrast could be made better. This mode does exactly that.
Click on the icon for reading mode again to exit reading mode.
These simulators all work in the same way. The portrait view shows the video output with a simulation of how a person with the respective condition would see it. Turning the device over to landscape mode would enable ‘headset mode’, which is stereoscopic video mode. Tapping on the video in this mode will make it go full-screen, and will be ready to be mounted on a VR headset for a more ‘immersive’ experience.
To exit headset mode, tap on the video again.
