REACT addresses causal completion of avatar motion when tracked joints are noisy or missing. It estimates joint reliability and coordinates current measurements with a short-horizon motion prediction and a smoother, longer-horizon candidate. In the shared synthetic-corruption evaluation, Ref-last REACT records 12.2 ± 6.6 degrees MPJLAE versus 20.6 ± 5.1 degrees for GRU-ctx-large; real tracking failures remain untested.
