摘要：We explore in this work users’ perceived workload, desirability, and usability of selecting mid-air targets representing TV menu options anchored to physical loci in 3-D space. Toward this end, we introduce a gesture-based selection technique and a spatial user interface for Smart TVs that consists of shortcuts to TV channels located in mid-air in front of the user’s body. Target selection is implemented with pointing and hand gestures recognized with the Myo armband. Ten participants evaluated our prototype and were elicited for feedback. We report empirical results about perceived usability (SUS=77.8), desirability (high frequency of positive connotation words),and workload (TLX=43.9) of our gesture-based selection technique and spatial user interface and discuss future work directions.
