Abstract

There is provided a method for determining if an object has been observed by user, said object being rendered in a graphical environment provided to a user with a head-mounted device, where the computer generated graphical environment is able to change over time, the method comprising the steps of: a) determining if the geometric proportion S of the size of the object, in relation to the total field of view generated in the graphical environment, is larger than a predetermined threshold value (Smin), and, if S is larger than Smin, determining for how long time (T) that S is greater than Smin, and if T is greater than a predetermined time Tmin, determining that the object has been observed by the user. There is also provided a method for placing objects in a graphical environment.

Dependent claims

A method for determining if an object rendered on a display of a head-mounted device has been observed by a user, said object being rendered in a computer-generated graphical environment provided on the display to a user with the head-mounted device, the method comprising the steps of:

a) using proportion determination software to determine the display area that is used to render the object,
b) using the proportion determination software to determine the proportion (S) of the area of step a) in relation to the total field of view generated in the graphical environment,
c) the proportion determination software providing S to observation determination software,
d) using the observation detection software to determine if the proportion of the display area used to render the object is larger than a predetermined threshold value (Smin), and, if S is larger than Smin, determining for how long time (T) that S is greater than Smin, and
if T is greater than a predetermined time Tmin, determining that the object has been observed by the user,
where the graphical environment is dependent on the direction of viewing of the user and wherein S is modified by a coefficient K, where said coefficient K is selected based on the angle α between the horizontal direction of the user's line of sight in the computer generated graphical environment and the horizontal direction from the point of observation of the user to a predefined point on the object, where α is determined by angle determination software and where K is constant for at least one interval of values of α,
or
where the object has a flat surface and the proportion S is modified by an incidence angle coefficient L, where L is selected based on the angle β between a vertical plane that is defined by the user's line of sight and a vertical plane that is perpendicular to the flat surface of the object, where β is determined by the angle determination software and where L is constant for at least one interval of values of β.

A system comprising a head-mounted device for rendering a graphical environment provided to a user on a display of the head mounted device, said system comprising a computer with a memory, the memory comprising observation detection software and area proportion determination software, and angle determination software,

said area proportion determination software being configured to determine the area of the display that is used to render the object, and to determine the proportion (S) of the area in relation to the total field of view of the graphical environment, and configured to provide S to the observation detection software,
said observation detection software being configured to receive S from the area determination software and configured to determine if S is larger than a predetermined threshold value (Smin), and configured to, if S is larger than Smin, determining for how long time (T) that S is greater than Smin, and configured to, if T is greater than a predetermined time Tmin, determine that the object has been observed by the user,
where the graphical environment is dependent on the direction of viewing of the user and where S is modified by a coefficient K, where said coefficient K is selected based on the angle α between the horizontal direction of the user's line of sight in the computer generated graphical environment and the horizontal direction from the point of observation of the user to a predefined point on the object, where K is constant for at least one interval of values of α, where α is determined by angle determination software, or
where the object has a flat surface and the proportion S is modified by an incidence angle coefficient L, where L is selected based on the angle β between a vertical plane that is defined by the direction of the user's line of sight and a vertical plane that is perpendicular to the flat surface of the object, where L is constant for at least one interval of values of β, where β is determined by the angle determination software.
