Electronic apparatus and display system
View Patent ↗An electronic apparatus capable of estimating the inclination of a head with a unit which is different from a unit like an acceleration sensor which directly detects the inclination of a housing and reflecting the inclination in the display is provided. The electronic apparatus includes an imaging device for detecting movement of an eyeball, a sight line detection device for detecting movement of a sight line on the basis of data obtained with the imaging device, an arithmetic device for performing an operation on display data based on the movement of the sight line, and a display device for performing display based on the display data. The electronic apparatus can estimate the inclination of a head with a unit which is different from a unit which is different from a unit like an acceleration sensor which directly detects the inclination of a housing and reflect the inclination in display.
1. An electronic apparatus comprising:
an imaging device configured to detect a movement of an eyeball;
a sight line detection device configured to calculate a movement of a sight line on the basis of a data obtained with the imaging device;
an arithmetic device configured to estimate a change in an inclination of a head based on the movement of the sight line and to speculatively generate a display data based on the estimated change in the inclination of the head before the head moves; and
a display device configured to display an image based on the display data.
2. The electronic apparatus according to claim 1 , further comprising an acceleration sensor configured to detect the inclination of the head,
wherein the arithmetic device is configured to generate the display data in accordance with the detected inclination of the head.
3. The electronic apparatus according to claim 1 , wherein the display device comprises a light-emitting element.
4. The electronic apparatus according to claim 1 , wherein the display device comprises a liquid crystal element.
5. The electronic apparatus according to claim 1 , wherein the display device is a retina scanning type projection device.
6. The electronic apparatus according to claim 1 , wherein the electronic apparatus is a head mounted display.
7. A display system comprising:
an electronic apparatus comprising:
an imaging device configured to detect a movement of an eyeball;
a sight line detection device configured to calculate a movement of a sight line on the basis of a data obtained with the imaging device;
an input/output device; and
a display device; and
an arithmetic device,
wherein the input/output device is configured to transmit a data on the movement of the sight line to the arithmetic device,
wherein the arithmetic device is configured to estimate a change in an inclination of a head based on the movement of the sight line and to speculatively generate a display data based on the estimated change in the inclination of the head before the head moves,
wherein the arithmetic device is configured to transmit the display data to the input/output device, and
wherein the display device is configured to display an image based on the display data.
8. The display system according to claim 7 , wherein the input/output device is configured to perform wireless communication with the arithmetic device.
9. The display system according to claim 7 , wherein the input/output device is connected to the arithmetic device through a communication cable.
