Envision is an app that can extract visual information from your surroundings and convert it to meaningful audio output. The functions of Envision are categorised into two tabs: Text, General and Scan & Find.
All the current and future text recognition functions will be found under this tab that can be always accessed easily. Within this tab you will find the following functions:
Tap the button and Envision will instantly read out any short text you’re pointing the camera at. Tap the button once again for Envision to stop reading.
If you intend to only read Dutch or other latin-based languages, you can turn on Offline Text Recognition from the Setting to make it even faster.
Envision can also automatically detect languages. If you tend to come across text in multiple languages in your everyday life, we recommend turning Automatic Language Detection on. If you mostly only read one language, its best if you keep it off.
Tap the button to capture a photo of the handwritten text you want Envision to read. Tap the button again for Envision to stop reading.
This could be used for reading neatly written greeting cards or notes.
Tap the button to activate the feature. Envision will provide audio guidance to adjust the document. It will then automatically capture a photo when all edges are visible. You can also manually take a picture by tapping in the middle of the screen. The recognised text appears on a new screen allowing you to:
• Navigate through the text using VoiceOver commands.
• Read the document by tapping the play button.
• Share the document by tapping the share button.
• Adjust the font size tapping the font button.
If you long press the ‘Read Documents’ button, you can scan and read multiple pages at once.
This function allows users with low vision to zoom into pieces of text they want to read.
This can be activated by simply using pinch and zoom on the screen or by pressing the magnifier icon on the top left corner. You can use any of the text recognition functions along with this mode. There is also an option to invert colours if you want to read texts with a higher contrast.
All functions that does not involve recognising text can be found under this tab. Currently, this tab offers the following functions:
Tap the button to capture a photo you want to be described. Envision will speak out the most probable description for it. If you have already taught Envision faces of your friends and family, they will be included in the description.
Envision also provides description based on the scene. When you take a photo of a watch, it tell you the time and when you take a picture of a window, it tells you the current weather.
You can save these images in your camera roll with their descriptions, which can be accessed with VoiceOver.
Tap the button and point the camera at the object or clothing you wish to recognise the color of. Envision will immediately start speaking out the color it sees. Tap the button again for Envision to stop recognising colors.
In the settings, you can select whether you want Envision to recognise just the standard 30 colors or the much more descriptive 950 colors.
Tap the button and point the camera at the product you want to recognise. Slowly move or rotate the product until you hear a beeping sound which means a barcode has been detected. Use the frequency of the beeping sound to bring the barcode in focus. You will hear a succesful ‘ting’ once the barcode has been successfully scanned.
You will then hear the product’s name. You can also learn more about the product by tapping ‘More Information’.
Envision allows you to teach faces and objects to it that can later be recognised through the Describe Scene function.
Tap on the Teach Envision button, this will take you to a screen with an option to 'Teach a face' and 'Teach an object'. Tapping any of those options takes you to a new screen, where you can start taking photos. By default the back camera of the phone is active, but this could be changed within the screen if you are intending to take a selfie. In the 'Teach a face' option, the camera will also provide a guide to help you position your face properly.
You are required to capture at least 5 photos, but we recommend taking around 10 photos for the recognition to be more accurate. Also, it helps if you take these photos from different angles and with different backgrounds. After clicking the photos, press Done. You will be prompted to enter the name of the person or the object. Once you do that, Envision will start teaching itself, which takes a few seconds. Once the teaching is successful you are taken back to the General Recognition tab.
Within the Teach Envision screen, you also have the option to Open Library. All the faces and objects that you have trained will be displayed here. You have the option to delete any of the faces or objects you no longer want Envision to recognise.
This tab helps you to use the real time recognition of the app to find people and objects around you. You will see the following options in this page:
Tap the button and scan your surroundings in real time. Envision will speak out the name of an object or face you have trained, whenever that appears in the frame. You can use this function to look for a friend in a cafe or find your keys on a table.
Tap the button and scan your surroundings in real time. Envision will speak out the names of general objects it sees in your surroundings like cup, laptop, chairs, etc.
Tap the button and select to teach Envision a face or an object. In the camera view, take at least 5 photos of a face and at least 10 photos of an object. Make sure these photos are from different angles and distances. Tap ‘Done’ once you have taken a sufficient number of photos.
Then, name the face or object and tap ‘Teach Envision’. It will take a few minutes for Envision to finish the training in the background, while you continue to use the app. You can manage the trained faces and objects in the library.
Envision can also be used to read and recognise images you come across in other apps like Photos, Twitter, WhatsApp, etc. This can be done by simply pressing the "Share" button from within that app and selecting the option "Envision it" from the list of actions that show up on the action sheet.
For the first time, you will have to enable this option by tapping on the "More" option in the bottom right corner of the share sheet and adding Envision It to the actions.
Envision is a constantly evolving app and we keep on improving its functions and capabilities. So make sure you either have your automatic updates on or check for new updates on a weekly basis. We will list a number of more tips here that we have crowdsourced from our users that may improve your experience of using Envision optimally:
