Before revision:  Our results show that the proposed algorithm successfully estimates human posture based only on the trajectory of the haptic-input device stylus. We additionally show that ergonomic risk estimates derived from our posture estimation approach are comparable to those estimates from gold-standard , motion-capture based pose estimates.
After revision:  Our results show that the proposed algorithm successfully estimates human postures and ergonomic risk scores comparable to those estimates from gold-standard , motion-capture based pose estimates.
