👁️ DrishtiAi - Real-Time Visual Help

📌 Overview

DrishtiAi is a visual assistant for people who are blind or have low vision. It uses the camera on your Android device to look at the world around you, find hazards, and speak what it sees in real time.

It can help with daily tasks like:

• Detecting obstacles in your path
• Warning about stairs, doors, and other hazards
• Reading basic scene details
• Giving spoken feedback while you move

DrishtiAi runs on the device, so it can work without sending camera data to a remote server. This keeps the app fast and helps support privacy.

🧪 Tips for Better Results

DrishtiAi works best when the camera gets a clear view of the area ahead.

Try these tips:

• Use bright light
• Keep the phone level
• Avoid covering the camera lens
• Hold the device at chest height or face height
• Point it where you plan to walk
• Stop and scan before moving through tight spaces

If detection feels weak:

• Move to a brighter spot
• Clean the lens
• Restart the app
• Make sure the camera permission is still enabled

🛠️ Troubleshooting

The app does not open

• Check that the install finished
• Restart your phone
• Try opening the app again

The camera does not work

• Confirm camera permission is on
• Close other apps that use the camera
• Restart the app
• Reboot the device if needed

No speech comes through

• Check the volume level
• Make sure silent mode is off
• Test with headphones removed
• Confirm speech output is enabled in the app

Detection feels slow

• Close other heavy apps
• Keep the device cool

🔧 Technical Notes

DrishtiAi uses Kotlin and TensorFlow Lite for on-device vision tasks. It is built for Android and uses machine learning models to process camera frames on the phone itself.

That setup helps the app:

• Respond with low delay
• Reduce network use
• Keep core vision work local
• Support use in places with weak or no internet
