It is possible for the SD card to become corrupted if unplugged or power failure, but it is rare. As shown in the project setup, the camera is mounted on a stand in such a position that if a paper is placed in between the area marked by angular braces, it captures a full view of the paper into the system. 5. Please refer to the project page for more details. The program makes use of the google translation service to record the spoken words. b. Yes, the speech sounds a bit like Stephen Hawking. OCR can be limited due to fonts, colors, text size, etc. Use an external audio converter (USB DAC) and have the volume control performed on that hardware without loss in quality. The commands will trigger specific actions, some of them depending on whether the user is navigating through the folder hierarchy (FolderBrowser) or actually playing a (non-metafile) mp3 file (MusicPlayer). Many of the things needed to be read are smaller text, so if the camera is too far away, it cant resolve. Android App which functions analogous to a white cane for the visually challenged using Computer Vision. 3) With notepad, create a file called wpa_supplicant.conf with following: Use Save As All files to K:\wpa_supplicant.confAgain, do not let Notepad change it to wpa_supplicant.conf.txt!! Once a mp3 file has been playing for a certain amount of time (we selected 30 seconds) a bookmark will be set automatically in the folder of the respective file when leaving the file. Limit the number of subfolders within the same hierarchy level to about 10 folders. When the camera takes the snapshot of the paper, it is ensured that there is a good lighting condition. When the camera takes the snapshot of the paper, it is ensured that there is a good lighting condition. It was created to make data science fun for the visually impaired. The image should be right side up, good contrast, in focus. Hello, everything seems to be working perfectly but the camera click sound when the button is pressed doesnt work, any help? For playing a new book, the "one button audio player" project (http://blogs.fsfe.org/clemens/2012/10/30/the-one-button-audiobook-player/) requires insertion of a USB stick loaded with the new book, while in another project (https://gist.github.com/wkjagt/814b3f62ea03c7b1a765) the already preloaded books are activated using specific RFID cards to be swiped over the RasPi.
