At a crowded Samsung booth, one attendant demonstrated how hand gestures were used to play simple kids' games. Raising her hand brought up an on-screen cursor. Grasping the air was equivalent to clicking on what her digital hand was hovering over.
However, when she tried the same gestures on a menu of TV-watching options, the TV didn't respond well. When she tried to give a kind of sideways wave — like Queen Elizabeth greeting her subjects — the page didn't swipe to the left as it should have.
Later, in a quiet, enclosed Samsung booth, the TV struggled to comprehend voice commands. The TV was asked, "find me a movie with Tom Cruise," and correctly pulled up an online trailer of his latest movie, "Jack Reacher." The system was then asked to "find me dramas." The command "Number 3" was given to choose the third option in the results, but the TV instead started a new search and offered a range of viewing options for "Sommersby."
