>From the draft spec: "Touch devices may also choose to reserve a portion of the touch interface for an unlock gesture." Mouse lock seems irrelevant on a touchscreen... I've added clarification to the draft spec in the use case section, "Touch screen device input All the application use cases are relevant on touch screen devices as well. A user should be permitted to make large gestures that are interpreted as movement deltas, without concern over the absolute positions of the touch points. Other UI elements from the user agent and system should be suppressed while under mouse lock. Absolute position of touch points should always be available, unlike mouse input where the concept of the cursor is removed. On a touch screen the absolute positions will always be relevant. Devices with no keyboard must provide escape from lock via either hard buttons or reserved screen space for an escape gesture."
