A method of displaying a guidance indicator to a user, the method comprising:
- receiving a series of images of a head of a user;
- determining, from each image of the series of images, information relating to a position of the head of the user;
- and
- displaying to the user, on a display screen, a guidance indicator associated with a representation of the head of the user only when each of one or more defined conditions regarding the position of the head is met, such that the user is provided with an indication that they are positioned suitably for the position of the head to be determined, wherein the defined conditions regarding the position of the head comprise one or more of the following:
- i) the information relating to the position of the head indicated that a change in the position of the head over a defined period is less than a defined threshold;
- and
- ii) the information relating to the position of the head indicated the head is rotated or tilted about an axis parallel to the display screen by less than a defined angular range from a normal to the display screen.
An apparatus for providing guidance to a user, the apparatus comprising:
- an imaging unit for receiving a series of images of a head of a user;
- a processing unit for determining, from each image of the series of images, information relating to a position of the head of the user;
- and
- a display screen, wherein the processing unit is configured to display, on the display screen, a guidance indicator associated with a representation of the head of the user only when each of one or more defined conditions regarding the position of the head is met, such that the user is provided with an indication that they are positioned suitably for the position of the head to be determined, wherein the defined conditions regarding the position of the head comprise one or more of the following:
- i) the information relating to the position of the head indicated that a change in the position of the head over a defined period is less than a defined threshold;
- and
- ii) the information relating to the position of the head indicated the head is rotated or tilted about an axis parallel to the display screen by less than a defined angular range from a normal to the display screen.
