This is a little project of mine aiming to research how vision LLMs could help out blind people on travel and in their every-day life by substituting eyesight for various visual tasks. VScan turns your smartphone's camera into a device for visual perception. You can define various optical cognitive functions, like looking for objects, signs, evaluating a scene or simply mediating visual impressions. You can afterwards use these functions on the camera view, just like a sighted person would use their eyes to achieve a specific goal in the physical world. Each cognitive tool consists of two major parts: • The camera to be used - front / back, as well as camera parameters - resolution, flashlight etc. • The prompts used for LLM processing. LLM is the bridge between raw pixel data and your interpretation of it, and in the user/system prompt, you can specify what exactly are you interested in for the particular function and how should it be communicated, as well as the LLM model that should be used. Camera input in combination with an LLM processing prompt forms a cognitive function, which can be used to serve various visual tasks. VScan is open-source software. Visit the project's official repository to learn more about its background, motivation, specific usage examples and setup instructions.

This app is for situations where you just cannot decide on rational grounds because of missing data or because the decision tree is so complex, a human could just flip a coin, because the computation of all outcomes would not be possible in the remaining life time. If you want to minimize the time you would normally lose in option paralysis, just press the big red button. The answer is a decisive and strict YES XOR NO. And there is also a delay to hinder you from fooling yourself and coming back to biased circles of fruitless thinking. But this is just what I think. Let me know what you think in the comments. ;) Everything is calculated locally, nothing is saved. Your data are yours. Nobody will ever learn about your specific love for wearing mismatched socks. How does it work Ask yourself a Yes/No question in your head You click the big red button Your answer will appear on the screen To prevent cheating, you can't go back for 5s.
