Microsoft's Kinect system hasn't gained a lot of traction amongst more hardcore gamers, but there's been a lot of curiosity about how it might be used in their preferred games. One possible example is shown by the enterprising team at PC Games Kinected, who have hooked it in to Skyrim:
Like the original Skyrim Kinect, you can use your arms to swing swords, cast spells, use your bow, or block with shieds. Movement, like walking/running and sneaking, is still handled with body movements and has seen an increase in precision. As a result, gameplay using the Bow is very enjoyable and preice.
As well, Voice Commands have been greatly improved. In Skyrim Kinect: Fus Ro Dah, you can use your voice to select up to 11 spells, to drink mana/health potions, to equip your sword/shield/bow, and to equip 2 different armor sets.
Voice Commands also allow you to say your favorite shouts (10 currently), by simply saying the dragon shout words of power. Not only can you say "Fus Ro Dah", you can also simply say "fus", or "fus roh". The majority of the shouts, which have multiple shout levels, use this approach.
