version: "1.0.0" name: tap-tapping description: Decode Tap tapcodes (which fingers tapped), map finger combinations to app actions or keyboard shortcuts, and give haptic feedback. Use for tapping, finger combos, chords, tap-to-action, shortcuts, input modes, or the TAPPING vision model.

Tapping

Works on every Tap. Start from the tap-getting-started skill for connection.

Tapcode bitmask

A tapcode is an int 1-31. Each bit is one finger:

Examples: 1 thumb, 2 index, 3 thumb+index, 6 index+middle, 31 all five.

FINGERS = ["thumb", "index", "middle", "ring", "pinky"]
def first(value):  # int or [int]
    return value[0] if isinstance(value, (list, tuple)) else value
def fingers(tapcode):
    return [name for bit, name in enumerate(FINGERS) if tapcode & (1 << bit)]
ACTIONS = {
    2: "next",       # index
    4: "previous",   # middle
    6: "select",     # index + middle
    31: "quit",      # all fingers
}
def on_tap(identifier, tapcode):
    action = ACTIONS.get(first(tapcode))
    if action:
        handle(action)

Single-finger taps are the most reliable. Prefer them for frequent actions. Use 2-finger combos next. Use 3+ finger combos only for rare actions.

Turn on tap events

After await sdk.start():

• If hasattr(sdk, "set_input_mode"): await sdk.set_input_mode(InputModeController()).
• InputModeText() (default): the Tap types letters on the OS keyboard. The SDK gets no taps.
• InputModeController(): the SDK gets tap, mouse, and air-gesture events. No typing.
• InputModeControllerText(): both at the same time.
• The SDK re-sends the mode every 10 s, so the device stays in it.
• Otherwise: set_feature(DeviceFeatures.MODEL_DETECTION, True), set_vision_sensor_model(ModelTypes.TAPPING), set_vision_sensor_op_mode(VisionSensorOpModes.TRIGGER).

Double taps and multi-taps

The SDK reports every tap. Detect double taps yourself with a time window:

import time
last = {"code": None, "t": 0.0}
def on_tap(identifier, tapcode):
    code, now = first(tapcode), time.monotonic()
    if code == last["code"] and now - last["t"] < 0.35:
        handle_double(code)
        last["code"] = None
        return
    last.update(code=code, t=now)
    handle_single(code)

If single and double must not both fire, delay the single action until the window ends (schedule it with loop.call_later(0.35, ...) and cancel it on the second tap).

Map taps to keyboard shortcuts

The SDK does not send OS key presses. Add a library in the user's app, for example pip install pynput:

from pynput.keyboard import Controller, Key
kb = Controller()
SHORTCUTS = {2: Key.right, 4: Key.left, 6: Key.space}
def on_tap(identifier, tapcode):
    key = SHORTCUTS.get(first(tapcode))
    if key:
        kb.press(key); kb.release(key)

macOS: the terminal / IDE needs Accessibility permission to send keys.

Haptic feedback

await sdk.send_vibration_sequence([80])              # short buzz
await sdk.send_vibration_sequence([100, 100, 100])   # double buzz

Values are on/off durations in ms (10-2550, max 18 values). From a sync callback, schedule it: asyncio.get_running_loop().create_task(sdk.send_vibration_sequence([80])).
