This is a great idea! That sensor is in perfect place and easy to operate for this purpose! The right clicking is quite critical, in Broken Sword you miss some of the feel because you cannot actually just look at the objects.

There is another problem concerning Broken Sword 1. The inventory bar opens in top of the screen. Even when playing in full screen mode and trying to handle the first object in inventory bar, the N900 application menu is triggered although it is not visible on screen.

One more thing is that there is no working escape-button in ScummVM. It would be nice to be able to skip the intro movies and whatever is skippable.
