Abstract

Embodiments relate to displaying textual data. Aspects of the embodiments includes receiving a request to display textual data and displaying textual data in a region within a display area. Displaying textual data includes sequentially presenting successive components of the textual data at a fixed position relative to the display area. Aspects of the embodiments also includes monitoring a point of gaze of a user based on biometric information, and based on detecting that the point of gaze is away from the region, automatically stopping the displaying by the processor at a time point corresponding to a current component, and determining a previous component of the textual data displayed at a previous time point. Aspects of the embodiments further include, based on detecting that the point of gaze has returned to the region, commencing by the processor the displaying at the previous component and continuing to display successive components of the textual data.

Claims

1. A system for displaying textual data, the system comprising:

a memory having computer readable instructions; and

a processor for executing the computer readable instructions, the computer readable instructions comprising;

receiving a request to display textual data;

displaying textual data in a reticle region within a display area, wherein the reticle region is moveable with respect to the display area, and wherein displaying textual data includes sequentially presenting successive components of the textual data at a fixed position relative to the reticle region within the display area;

monitoring a point of gaze of a user based on biometric information;

based on detecting that the point of gaze is away from the reticle region, automatically stopping the displaying at a current time point at which a current component is displayed, and determining a previous component of the textual data that was displayed at a previous time point, the previous time point occurring a rewind time period prior to the current time point, wherein the rewind time period between the previous time point and the current time point is determined based at least in part on a reading speed of the user; and

based on detecting that the point of gaze has returned to the reticle region, displaying the previous component associated with the previous time point and continuing to display successive components of the textual data subsequent to the previous component.

2. The system of claim 1, wherein the displaying includes detecting whether the point of gaze is at the reticle region within the display area.

3. The system of claim 1, wherein the displaying includes presenting the successive components at a display speed corresponding to an initial time window during which each successive component is presented in the reticle region.

4. The system of claim 3, wherein the instructions further comprise monitoring at least one biometric characteristic of the user during the displaying, and controlling the display speed based on the at least one biometric characteristic.

5. The system of claim 4, wherein the monitoring the at least one biometric characteristic includes detecting whether the user is experiencing at least one of stress and fatigue.

6. The system of claim 5, wherein the controlling the display speed includes reducing the display speed by the processor in response to determining that the user is experiencing at least one of stress and fatigue.

7. The system of claim 1, wherein the monitoring the point of gaze includes receiving biometric data from at least one sensor, the biometric data indicating at least one of eye movement and a position of one or more components of an eye.

8. The system of claim 1, wherein the reticle region of the display area is defined by a reticle on which successive textual data components are displayed.

9. The system of claim 1, wherein sequentially presenting successive components of the textual data comprises presenting a first word for a period of time, and, responsive to expiration of the period of time, implementing an animation transition before presenting a second word.

10. The system of claim 9, wherein the animation transition is a fading transition.

11. The system of claim 9, wherein the animation transition is a flipping transition.

12. A computer program product for displaying textual data, the computer program product comprising:

a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a signal, the program instructions readable by a processing circuit to cause the processing circuit to perform a method comprising;

receiving a request to display textual data;

displaying textual data in a reticle region within a display area, wherein the reticle region is moveable with respect to the display area, and wherein displaying textual data includes sequentially presenting successive components of the textual data at a fixed position relative to the reticle region within the display area;

monitoring a point of gaze of a user based on biometric information;

based on detecting that the point of gaze is away from the region, automatically stopping the displaying at a current time point at which a current component is displayed, and determining a previous component of the textual data that was displayed at a previous time point, the previous time point occurring a rewind time period prior to the current time point, wherein the rewind time period between the previous time point and the current time point is determined based at least in part on a reading speed of the user; and

based on detecting that the point of gaze has returned to the region, displaying the previous component associated with the previous time point and continuing to display successive components of the textual data subsequent to the previous component.

13. The computer program product of claim 12, wherein the displaying includes presenting the successive components at a display-speed corresponding to an initial time window during which each successive component is presented in the reticle region.

14. The computer program product of claim 13, wherein the method further comprises monitoring at least one biometric characteristic of the user during the displaying, and controlling the display speed based on the at least one biometric characteristic.

15. The computer program product of claim 14, wherein the monitoring the at least one biometric characteristic includes detecting whether the user is experiencing at least one of stress and fatigue, and controlling the display speed includes reducing the display speed by the processor in response to determining that the user is experiencing at least one of stress and fatigue.
