Abstract

The present invention relates to an apparatus and method for designing a display for user interaction. The proposed apparatus includes an input unit for receiving physical information of a user and a condition depending on a working environment. A space selection unit selects an optimal near-body work space corresponding to the condition received by the input unit. A space search unit calculates an overlapping area between a viewing frustum space, defined by a relationship between a gaze of the user and an optical system of a display enabling a 3D image to be displayed, and the optimal near-body work space selected by the space selection unit. A location selection unit selects a location of a virtual screen based on results of calculation. An optical system production unit produces an optical system in which the virtual screen is located at the location selected by the location selection unit.

First claim

What is claimed is:

1. An apparatus for designing a display for user interaction, comprising:
an input unit for receiving physical information of a user and a condition depending on a working environment;
a space selection unit for selecting an optimal near-body work space corresponding to the condition received by the input unit and based on the physical information of the user, including an area in which the user is capable of interacting with a virtual screen near a body of the user in the working environment;
a space search unit for calculating an overlapping area between a viewing frustum space, defined by a relationship between a gaze of the user and an optical system of a display enabling a three-dimensional (3D) image to be displayed, and the optimal near-body work space selected by the space selection unit;
a location selection unit for selecting a location of the virtual screen based on results of calculation by the space search unit; and
an optical system production unit for producing an optical system in which the virtual screen is located at the location selected by the location selection unit,
wherein the optical system production unit incorporates a value of a parameter indicative of a distance from the user's pupil to the virtual screen into values obtained via the space selection unit, the space search unit, and the location selection unit,
wherein the optical system production unit produces an optical system so that a 3D User Interface (UI) menu is displayed in a space defined by a length of 10 cm in an approaching direction and a length of 20 cm in a receding direction with respect to a viewing distance of 40 cm to 50 cm from the eyes of the user to the virtual screen.

2. The apparatus of claim 1 , wherein the space selection unit maps spatial data having a shape of a 3D volume to a work space depending on a body of the user, based on a value output via searching of pre-stored information, and selects the mapped work space as the optimal near-body work space.

3. The apparatus of claim 1 , wherein the space search unit forms the viewing frustum space, and calculates an overlapping area by arranging the optimal near-body work space and the viewing frustum space to overlap each other.

4. The apparatus of claim 1 , wherein the location selection unit enables the virtual screen to be formed at a location at which a viewing distance from eyes of the user to the virtual screen is 40 cm to 50 cm.

5. A method for designing a display for user interaction, comprising:
receiving, by an input unit, physical information of a user and a condition depending on a working environment;
selecting, by a space selection unit, an optimal near-body work space corresponding to the received condition and based on the physical information of the user, including an area in which the user is capable of interacting with a virtual screen near a body of the user in the working environment;
calculating, by a space search unit, an overlapping area between a viewing frustum space, defined by a relationship between a gaze of the user and an optical system of a display enabling a three-dimensional (3D) image to be displayed, and the optimal near-body work space selected at selecting the optimal near-body work space;
selecting, by a location selection unit, a location of the virtual screen based on results of calculation at calculating the overlapping area; and
producing, by an optical system production unit, an optical system in which the virtual screen is located at the location selected at selecting the location,
wherein producing the optical system is configured to incorporate a value of a parameter indicative of a distance from the user's pupil to the virtual screen into values obtained via selecting the space, calculating the overlapping area, and selecting the location, and
wherein producing the optical system is configured to produce an optical system so that a 3D User Interface (UI) menu is displayed in a space defined by a length of 10 cm in an approaching direction and a length of 20 cm in a receding direction with respect to a viewing distance of 40 cm to 50 cm from the eyes of the user to the virtual screen.

6. The method of claim 5 , wherein selecting the space comprises:
mapping spatial data having a shape of a 3D volume to a work space depending on a body of the user, based on a value output via searching of pre-stored information; and
selecting the mapped work space as the optimal near-body work space.

7. The method of claim 5 , wherein calculating the overlapping area comprises:
forms the viewing frustum space; and
calculating an overlapping area by arranging the optimal near-body work space and the viewing frustum space to overlap each other.

8. The method of claim 5 , wherein selecting the location is configured to enable the virtual screen to be formed at a location at which a viewing distance from eyes of the user to the virtual screen is 40 cm to 50 cm.

9. The method of claim 5 , further comprising correcting, by a correction unit, image blurring and image distortion occurring in the display that enables the 3D image to be displayed and that includes the optical system produced at producing the optical system.

10. The method of claim 9 , wherein correcting is configured to inwardly rotate an optical system module of the display enabling the 3D image to be displayed at a predetermined angle.

11. The method of claim 9 , wherein correcting is configured to inwardly rotate an optical system module of the display enabling the 3D image to be displayed at a predetermined angle, and rotate an image output module in a direction opposite to a rotating direction of the optical system module.

12. An apparatus for designing a display for user interaction, comprising:
an input unit for receiving physical information of a user and a condition depending on a working environment;
a space selection unit for selecting an optimal near-body work space corresponding to the condition received by the input unit and based on the physical information of the user, including an area in which the user is capable of interacting with a virtual screen near a body of the user in the working environment;
