Inverse Kinematics (IK) is a way of procedurally changing the animations applied to a model so that the interactions that, that model makes appear to be more natural. In this case I am planning on using IK to modify the position of the fingers when a user grabs an object. This is taken from the research I have conducted from writers such as Casey Fictum as well as the primary research that I conducted. They agree with the point that VR should emulate real world interactions as closely as possible if trying to simulate something realistic. I hope that the introduction of IK will provide this to the user and they will feel as if they are more connected to the world that they are being immersed in through the use of VR.
This video shows the current state of the hand IK solutions this was several days of programming and fine tuning to get it to this state of completion unfortunately due to the fact I want the character to move their are some strange artefacts that occur with the hand such as the fingers wiggling and snapping unnaturally. Which is more detrimental to the user than having fixed animation states for different models. At this time I am planning on going with fixed animation states for each model as this will currently not do as it ruins the immersion for the user.
I plan on exploring this and fixing it at a later date if time permits but as the deadline approaches I do not thing I will have time to do this due to the fact I think the code will need a full rewrite and I think that time can be spent more wisely in progressing the project forward in other areas.
