Abstract

A method, a system, and an information handling system dynamically provide individualized dynamic digital display correction for users of an electronic device. An information handling system detects a login of a first user profile that is associated with a first user. The information handling system then determines whether the first user profile has an associated first vision profile. In response to the first user profile having an associated first vision profile, a vision correction value associated with the first user is identified. A first change in image characteristics that may be applied to a graphical user interface (GUI) in order to achieve the vision correction value is calculated and applied to one or more content displayed on the GUI.

First claim

What is claimed is:

1. A method comprising:
detecting, at an information handling system, a login of a first user profile associated with a first user;
in response to detecting the login of the first user profile, determining whether the first user profile has an associated first vision profile; and
in response to the first user profile having an associated first vision profile:
identifying, from the first vision profile, a vision correction value associated with the first user;
calculating a first change in image characteristics that may be applied to a graphical user interface (GUI) in order to achieve the vision correction value;

applying the first change in image characteristics to the GUI, wherein the GUI is displayed with at least the first change in image characteristics applied to one or more content of the GUI.

2. The method of claim 1 , wherein the information handling system has a user-facing camera, and wherein detecting the login by the first user profile further comprises:
dynamically detecting a presence of a current user of the information handling system;
performing, with the user-facing camera, a facial recognition of the current user of the information handling system;
comparing identifying characteristics from the facial recognition of the current user with facial recognition profiles known to the information handling system to determine whether any of the facial recognition profiles includes identifying characteristics that match characteristics from the facial recognition of the current user; and
in response to finding a match of identifying characteristics from a facial recognition profile of the first user from among the facial recognition profiles:
identifying the current user as the first user; and
logging the first user profile in to at least one software running on the information handling system that generates the GUI.

3. The method of claim 1 , further comprising:
in response to determining the first user profile does not have an associated vision profile, establishing the associated vision profile for the first user profile, wherein establishing, the associated vision profile further comprises:
setting a font size of the GUI to a largest size;
performing a vision test comprising:
displaying a character string on the display, wherein the character string comprises one or more alphanumeric values and symbols from among letters, numbers, and punctuation;
requesting the first user reenter the displayed character string;
receiving a user entry in response to the request;
in response to receiving the user entry, determining whether the user entry is a match to the displayed character string;
in response to determining the user entry is a match to the displayed character string: adjusting the font size of the GUI to a next smaller size and reinitializing the vision test; and
in response to determining the user entry of the character string is not a match to the displayed character string: creating the associated vision profile of the first user profile and recording, within the associated vision profile for the first user profile, a plurality of vision characteristics based on the vision test and a smallest size of the font size that was correctly identified by the first user.

4. The method of claim 3 , further comprising:
detecting whether the first user is wearing at least one of corrective contact lenses and corrective lenses;
in response to detecting that the first user is wearing corrective lenses:
requesting the first user remove the corrective lenses before initializing the vision test; and
preventing initialization of the vision test until it has been detected that the first user is not wearing corrective lenses; and

in response td detecting that the first user is wearing corrective contact lenses, postponing the vision test unless the user requests the vision test and removes the corrective contact lenses.

5. The method of claim 3 , wherein the information handling system includes a microphone and the vision test supports a verbal recitation of the character string, the method further comprising:
recording the verbal recitation of the user entry of the character string via the microphone; and
performing an audio analysis of the recorded verbal recitation to determine a spoken content of the recorded verbal recitation, wherein the spoken content is the user entry of the character string.

6. The method of claim 1 , further comprising:
detecting whether the first user is wearing at least one of corrective contact lenses and corrective lenses; and
in response to detecting that the first user is wearing at least one of corrective contact lenses and corrective lenses:
removing the application of the first change in image characteristics from the GUI;
periodically monitoring for removal by the user of the at least one of corrective contact lenses and corrective lenses; and
in response to detecting that the first user is no longer wearing the at least one of the corrective contact lenses and the corrective lenses, re-applying the first change in image characteristics to the GUI.

7. The method of claim 2 , further comprising:
dynamically measuring, via the user-facing camera, a distance between the first user and the information handling system; and
dynamically adjusting the first change in image characteristics to the GUI based on the distance between the first user and the information handling system.

8. An information handling system comprising:
at least one processing device;
a memory;
a digital display correction utility that when executed by the at least one processing device, enables the information handling system to:
detect, at an information handling system, a login of a first user profile associated with a first user;
in response to detecting the login of the first user profile, determine whether the first user profile has an associated first vision profile; and
in response to the first user profile having an associated fust vision profile:
identify, from the first vision profile, a vision correction value associated with the first user;
calculate a first change in image characteristics that may be applied to a graphical user interface (GUI) in order to achieve the vision correction value;
apply the first change in image characteristics to the GUI, wherein the GUI is displayed with the first change in image characteristics applied to one or more content of the GUI.

9. The information handling system of claim 8 , further comprising a user-facing camera, wherein to enable the information handling system to detect the login by the first user profile further comprises the digital display correction utility enabling the information handling system to:
dynamically detect a presence of a current user of the information handling system;
perform, with the user-facing camera, a facial recognition of the current user of the information handling system;
compare identifying characteristics from the facial recognition of the current user with facial recognition profiles known to the information handling system to determine whether any of the facial recognition profiles includes identifying characteristics that match characteristics from the facial recognition of the current user; and
in response to finding a match of identifying characteristics from a facial recognition profile of the first user from among the facial recognition profiles:
identify the current user as the first user; and
log the first user profile in to at least one software running on the information handling system that generates the GUI.

10. The information handling system of claim 8 , further comprising the digital display correction utility en
