US 2018/0004547 A1 · ASSISTIVE TECHNOLOGY NOTIFICATIONS FOR RELEVANT METADATA CHANGES IN A DOCUMENT

Abstract

User interface information related to relevant events of interest is provided. Events can occur anywhere in a document, and may or may not be relevant to a user utilizing an assistive technology (AT) application, such as a screen reader. A provider-side signaling system component determines whether raised events are relevant to the user. In some examples, when an application makes a plurality of attribute changes in a document at once, the signaling provider batches the related events as a single transaction, and generates a generalized annotation describing the changes. The signaling provider further packages the event notification, and sends the event notification to a client-side signaling system component. The signaling client receives the notification, and determines whether to alert the user of the event(s) based on verbosity settings. The AT application is enabled to interpret the event notification and alert the user in a meaningful way.

Dependent claims

A computer-implemented method for providing a signaling system for notifying an assistive technology (AT) application user of metadata changes in a document, comprising:

at a provider-side of the signaling system:
receiving an indication of a change of an attribute on a text range in a document;
determining whether the attribute change is relevant to the AT application user;
and
when a determination is made that the attribute change is relevant to the AT application user, sending an event notification of the attribute change to a client-side of the signaling system;
and
at a client-side of the signaling system:
receiving the event notification of the attribute change;
determining whether to alert the AT application user of the attribute change based on settings;
and
when a determination is made to alert the AT application user of the attribute change, generating an alert for notifying the AT application user of the attribute change.

A system for notifying an assistive technology (AT) application user of metadata changes in a document, the system comprising a computing device, the computing device comprising:

at least one processing device;
and
at least one computer readable data storage device storing instructions that, when executed by the at least one processing device are operative to provide:
a provider-side signaling system operative to:
receive an indication of a change of an attribute on a text range in a document;
determine whether the attribute change is relevant to the AT application user;
and
when a determination is made that the attribute change is relevant to the AT application user, send an event notification of the attribute change to a client-side of the signaling system;
and
a client-side signaling system operative to:
receive the event notification of the attribute change;
determine whether to alert the AT application user of the attribute change based on settings;
and
when a determination is made to alert the AT application user of the attribute change, generate an alert for notifying the AT application user of the attribute change.
