Flowchart diagram of the data acquisition (purple), processing pipeline (yellow for pre-processing, blue for amplitude features processing, and red for entropy features processing), and classification (gray) phases of our proposed method. Note that the Dataset 1 uses Visual guidance and a combination of Visual guidance and Vibrotactile guidance, and the Dataset 2 uses Visual cue only
