Abstract: Aiming at the limited capacity of single input modality,hybrid input techniques with touch,pen and mid-air gestures were proposed.First,the performance of touch,pen and mid-air gestures was investigated.Then,10 hybrid input techniques with 2 or 3 modalities were proposed and investigated according to operation complexity.Results showed that,compared to Single-modality Pen(S-P),Double-modality Parallel Touch+Pen(DP-T+P)performed the best in parallel situation.And Double-modality 2-Dimensional Touch Click+Pen(D2D-TC+P)performed the best in 2-dimensional situation.Although subjects committed the fewest mistakes in the hybrid input techniques with mid-air gestures,they gave it the worst subjective evaluation.The discussions and conclusions can be used as reference for hybrid interaction and interface design with touch,pen and mid-air gestures.
