1. A display system comprising:
a remote control apparatus including a motion sensor and keys, the keys comprising a left direction key, a right direction key, an up direction key and a down direction key; and
a display apparatus including:
a display,
a communication unit configured to enable communications with the remote control apparatus, and
a controller configured to:
operate in a step mode in which a focus is stepwise movable among menu items displayed on the display in a direction in accordance with manipulation of the left direction key, the right direction key, the up direction key and the down direction key,
determine multi-directional spatial movements of the remote control apparatus along a spatial path sensed by the motion sensor,
obtain a signal sensed by the motion sensor based on determining the multi-directional spatial movements,
switch from the step mode to a pointing mode in which a pointer is displayed on the display and the pointer is moveable in a direction in accordance with a spatial movement of the remote control apparatus based on the signal sensed by the motion sensor and operate in the pointing mode in which the pointer is displayed on the display and moveable in accordance with the spatial movement of the remote control apparatus sensed by the motion sensor, and
switch from the pointing mode to the step mode in response to receiving, through the communication unit, a signal corresponding to manipulation of a key among the keys from the remote control apparatus.
