Fig. 6From: Stable haptic feedback generation for mid-air gesture interactions: a hidden Markov model-based motion synthesis approachQualitative results. The comparative plot of different motion profiles during horizontal drag gesture execution under unstable tracking conditions. The synthesized motion data is smooth and best replicates the reference motion pattern. By comparison the measured motion data has high fluctuations making the vibrotactile feedback unrealistic and unpleasantBack to article page
