Accessibility & Sensory Tools
If the rest of this app is about managing documents and files, this chapter is about something more fundamental: putting your phone's camera, sensors, and accessibility hooks directly in service of your independence. Every tool here turns a piece of hardware you already carry — a lens, a light sensor, a magnetometer, a GPS chip — into something that speaks to you in plain language.
Talking Camera and Object Detection both use the rear camera, but for different purposes: one reads documents and frames photographs for you, the other names the things in front of the lens in real time. The Ambient Light Detector and Vibration Compass turn invisible physical properties — brightness and direction — into spoken numbers, audio tones, and vibration patterns you can feel through your fingertips. Focus Bridge is different again: it's a system-level accessibility service that can read and interact with the screen of almost any app on your phone, not just this one, filling in gaps where another app's own accessibility support falls short. Location Announcer speaks your surroundings on demand, Time & Battery Announcer keeps you informed in the background without you ever opening the app, and Screen Recorder captures your device's display when you need a record of what happened on screen.
Every one of these tools was built and tested against a screen reader from the start, which is a different discipline than adding accessibility labels to a sighted-first design afterward. Buttons announce what they do before you press them. Settings are grouped logically and explained in the moment, not buried in a manual. Where a feature runs entirely on-device — as several in this chapter do — you'll be told plainly, because knowing your data isn't leaving your phone matters.
Taken together, these are the tools that make Tech Assistant feel less like an app and more like a companion device: the ones you reach for not to manage a file, but to understand a room, a document, a direction, or a stretch of unfamiliar street. Work through them once with a bit of patience, and each one becomes a reflex.
