Portable electronic apparatus including a display and method for controlling display content based on movement of the display and user position
First Claim
1. Portable electronic apparatus includinga display configured to display content;
- a user position estimating unit for estimating a position of a user with respect to the display; and
a display movement estimating unit for estimating movement of the display; and
wherein the apparatus is configured forestimating, with the user position estimating unit, an initial position of the user, at a first moment;
during an interval of time after the first moment, estimating, with the display movement estimating unit, the display movement, and controlling the display content based on the display movement and the initial position of the user,the apparatus being further configured, before estimating the position of the user, fordetermining whether a user is present in front of the display, and,wherein controlling the display content based on the display movement and the initial position of the user includes generating, if it is determined that a user is present in front of the display, on the display a three-dimensional effect based on the display movement and the initial position of the user, andif it is determined that no user is present, operating the apparatus in a non-three-dimensional effect mode wherein no three-dimensional effect is generated on the display.

Abstract
A portable electronic apparatus includes a display, a user position estimating unit and a display movement estimating unit. The user position estimating unit is for estimating the user position with respect to the display. The display movement estimating unit is for estimating the display movement. The apparatus is configured for estimating the user position, here referred to as initial user position, at least at a first moment; and, during at least an interval of time after the first moment, estimating the display movement, and controlling the display content based on the initial user position and the display movement. The invention also relates a method for controlling such an apparatus and to a computer program therefor.

1. Portable electronic apparatus including
a display configured to display content; -
a user position estimating unit for estimating a position of a user with respect to the display; and a display movement estimating unit for estimating movement of the display; and wherein the apparatus is configured for estimating, with the user position estimating unit, an initial position of the user, at a first moment; during an interval of time after the first moment, estimating, with the display movement estimating unit, the display movement, and controlling the display content based on the display movement and the initial position of the user, the apparatus being further configured, before estimating the position of the user, for determining whether a user is present in front of the display, and, wherein controlling the display content based on the display movement and the initial position of the user includes generating, if it is determined that a user is present in front of the display, on the display a three-dimensional effect based on the display movement and the initial position of the user, and if it is determined that no user is present, operating the apparatus in a non-three-dimensional effect mode wherein no three-dimensional effect is generated on the display. - View Dependent Claims (2, 3, 4, 5, 6)

7. Portable electronic apparatus including
a display configured to display content; -
a user position estimating unit for estimating a position of a user with respect to the display; and a display movement estimating unit for estimating movement of the display; and wherein the apparatus is configured for estimating, with the user position estimating unit, an initial position of the user, at a first moment; during an interval of time after the first moment, estimating, with the display movement estimating unit, the display movement, and controlling the display content based on the display movement and the initial position of the user, the apparatus being further configured for determining, before estimating the position of the user, whether a plurality of users are present in front of the display, and, if it is determined that a plurality of users are present in front of the display, selecting one of the users for the step of estimating the position of the user, wherein selecting one of the users is based on at least one of determining a user'"'"'s face which is the closest to the display; determining a user'"'"'s face which is the biggest as seen from the display; determining a user'"'"'s face which is the closest to a perpendicular originating from the center of the display; determining a user'"'"'s face which is the closest to the center of the field of view of a camera of the apparatus;
ordetermining that a face of one of the users is recorded in the apparatus.

8. Method for controlling a portable electronic apparatus including a display configured to display content, the method including steps of
at a first moment, estimating an initial position of a user with respect to the display; -
during an interval of time after the first moment, estimating movement of the display, and controlling the display content based on the display movement and the initial position of the user, wherein controlling the display content based on the display movement and the initial position of the user includes generating on the display a three-dimensional effect based on the display movement and the initial position of the user, and further including, before estimating the initial position of the user, steps of determining whether a user is present in front of the display, and, if it is determined that no user is present, switching the apparatus to a non-three-dimensional effect mode wherein no three-dimensional effect is generated on the display. - View Dependent Claims (9, 10, 11, 12, 13, 14, 16)
