Tiny Compose Multiplatform utility for reading the current environment's factual interaction capabilities.

Use it when a design system needs to adapt component sizing, spacing, or interaction affordances based on whether touch, pointer, or keyboard input is available.

This is a small helper library until Compose media query APIs are stable and available across Compose Multiplatform targets.

dependencies {
    implementation("com.composables:compose-interaction-capabilities:1.0.0")
}

import androidx.compose.runtime.Composable
import com.composables.interactioncapabilities.currentInteractionCapabilities

@Composable
fun Component() {
    val capabilities = currentInteractionCapabilities()
    val useTouchSizes = capabilities.hasTouch

    // Map capabilities to your own design-system sizing rules.
}

• Web and Wasm use browser media queries:
  • hasTouch = matchMedia("(any-pointer: coarse)").matches
  • hasPointer = matchMedia("(any-pointer: fine)").matches
  • hasKeyboard = true
  • Compose state updates when the media query result changes.
• JVM Desktop uses AWT to detect headless environments and pointer availability. hasTouch remains false because standard JVM/AWT does not expose a reliable touch capability query. hasKeyboard reports whether desktop keyboard input is available through AWT, not a low-level hardware inventory.
• Android checks PackageManager for touch support and InputDevice/configuration for pointer and keyboard devices. The conservative baseline is touch-first.
• iOS returns hasTouch = true, hasPointer = false, and uses GCKeyboard to report whether a hardware keyboard is currently connected. Pointer remains conservative because iOS/iPadOS exposes pointer interactions and events, not a reliable public connected-pointer query for this tiny Compose-only API.

• iOS Simulator Arm64

The :demo project renders the current InteractionCapabilities result using the published API from this repository.

./gradlew :demo:run
./gradlew :demo:jsBrowserDevelopmentRun
./gradlew :demo:wasmJsBrowserDevelopmentRun
./gradlew :demo:installDebug

For iOS, the demo module builds an InteractionCapabilitiesDemo framework with a MainViewController() entry point.
