    Maybe solve it in this manner:

    case { device: Touchscreen }:
    case { device: Mouse }:
        var a = x.device;
        . . .
    

    or

    case { device: Mouse or Touchscreen }:
        var a = x.device;
        . . .
    

    where x is the object that is currently analysed.

    Probably it depends on other details.
