The Sony PS3 3D Shutter Glasses are disassembled by removing 6 very small cross-headed screws, then pulling the glasses apart into separate halves.

Two screws hold in the nosepiece.Two more are on each side, by the hinges.  Fold the arms to expose them.

2 on the left, 2 on the right.  With all the screws removed, carefully pull the back "half" of the glasses frame away from the front "half" of the frame.  The center part will be held by a bit of glue.  

This is a tedious process but it's doable.

The "front" half of the frame contains all the worky bits.  A small rechargeable li-po cell and main circuitboard with IR receiver are in the center over the nosepiece.  On the right is the power switch.

With the glasses disassembled (and some degree of confidence in re-assembling them), the next step will be to figure out how to trigger the LCD shutters on demand.  

(The existing electronics are not likely to be useful, since they'll be all about detecting a valid IR video sync signal and correspondingly shuttering the left and right lenses for very brief periods of time.)
