SightAdapt 0.5 Alpha

SightAdapt is an open-source visual-accessibility application for Windows 10 and Windows 11. It applies configurable visual correction to selected application windows through a separate input-transparent overlay. It does not modify another application's files or process memory.

Current version

Product version: 0.5.0-alpha.1+<commit>

The commit suffix in ProductVersion identifies the exact source revision used to build the executable.

Functionality

SightAdapt currently provides:

• persistent per-application visual-profile assignments;
• automatic activation for enabled application assignments;
• fixed Exact invert and editable Soft invert profiles;
• independent user-defined Soft Invert profiles;
• output-black, output-white, brightness, contrast, saturation, and hue controls;
• grayscale and hue-spectrum profile previews;
• create, duplicate, rename, edit, assign, and delete operations for user-defined profiles;
• per-application overlay scope: client area, full window, current screen, or all screens;
• foreground-window detection every 75 ms with duplicate suppression;
• a bounded runtime application-identity cache;
• reuse and retargeting of one overlay instance during normal application switching;
• a short transition grace period that reduces visible white flashes;
• two global shortcuts;
• a notification-area menu and configuration panel;
• immediate explicit and emergency overlay shutdown;
• schema-versioned JSON settings with migration and atomic persistence;
• automated build, test, architecture, migration, and Windows publish validation.

New application assignments use Soft Invert and client-area scope by default.

Keyboard controls

Shortcut	Action
Ctrl+Alt+I	Locally enable or disable visual correction for the active window without changing saved settings
Ctrl+Alt+Shift+I	Add, disable, or re-enable the active application's persistent automatic assignment

Emergency shutdown is available from the notification-area menu.

Build a standalone EXE

The application can be published as a self-contained single-file executable. It does not need to be started with dotnet run, and the target computer does not need a separately installed .NET runtime.

Detailed instructions: docs/BUILD.md.

From the repository root:

dotnet restore .\src\SightAdapt\SightAdapt.csproj

dotnet publish .\src\SightAdapt\SightAdapt.csproj `
    --configuration Release `
    --runtime win-x64 `
    --self-contained true `
    -p:PublishSingleFile=true `
    --output .\artifacts\win-x64

The executable is created at:

artifacts\win-x64\SightAdapt.exe

Current limitations

• only one foreground target is corrected at a time;
• background or fully obscured windows are not persistently filtered by the current Magnification API backend;
• profile import and export are not implemented;
• palette analysis, dominant-color extraction, targeted color rules, and LUT import are not implemented;
• protected or DRM-controlled content may not be capturable;
• elevated applications may require SightAdapt to run at a compatible integrity level;
• remote-desktop sessions and some graphics drivers may not support the magnifier control correctly;
• endurance and broad compatibility testing are not complete.
