Computing unit for ascertaining the viewing vector of a user of smart glasses

A computing unit for ascertaining a viewing vector of a user of smart glasses, wherein the computing unit is configured to:

• receive first image data recorded using a first sensor unit at a first time interval including at a first time range, and to generate at least one image of an eye of the user based on the recorded first image data;
• receive first rotational speed data of the user's eye recorded using a second sensor unit at a second time interval including a second time range, wherein the second time interval is smaller than the first time interval;
• ascertain at least a first viewing vector information of the user of the smart glasses based on the generated image of the user's eye, and ascertain at least a second viewing vector information of the user's eye based on the received first rotational speed data of the user's eye;
• and
• ascertain the viewing vector of the user's eye based on the ascertained first and/or second viewing vector information.

An optical system for ascertaining a viewing vector of a user of smart glasses, comprising:

• a first sensor unit configured to record first image data at a first time interval including at a first time range;
• a second sensor unit configured to record first rotational speed data of the user's eye at a second time interval including at a second time range, wherein the second time interval is smaller than the first time interval;
• and
• a computing unit configured to:
• receive the first image data recorded using the first sensor unit at the first time interval including at the first time range, and to generate at least one image of an eye of the user based on the recorded first image data,
• receive the first rotational speed data of the user's eye recorded using the second sensor unit at the second time interval including the second time range,
• ascertain at least a first viewing vector information of the user of the smart glasses based on the generated image of the user's eye, and ascertain at least a second viewing vector information of the user's eye based on the received first rotational speed data of the user's eye, and
• ascertain the viewing vector of the user's eye based on the ascertained first and/or second viewing vector information.

A method for ascertaining a viewing vector of a user of smart glasses, the method comprising the following steps:

• receiving first image data recorded at a first time interval at a first time range, using a first sensor unit;
• generating in each case at least one image of an eye of the user based on the recorded first image data, and
• receiving first rotational speed data of the user's eye recorded at a second time interval at a second time range, using a second sensor unit, wherein the second time interval is smaller than the first time interval;
• ascertaining at least a first viewing vector information of the user of the smart glasses on the basis of the generated image of the user's eye;
• ascertaining at least a second viewing vector information of the user based on the received first rotational speed data of the user's eye;
• and
• ascertaining the viewing vector of the user's eye based on the ascertained first and/or the ascertained second viewing vector information.
