Retrieving and displaying key words from prior conversations

A wearable apparatus, the wearable apparatus comprising:

• a wearable image sensor;
• and
• at least one processor programmed to:
• receive, from the wearable image sensor, a facial image of an individual with whom a user of the wearable apparatus interacted in a first interaction during a time window;
• receive sound data captured in a vicinity of the image sensor during at least a part of the time window;
• process the sound data to identify at least one key word;
• store in memory an association between the key word and the facial image;
• receive, from the wearable image sensor, another facial image of the individual during a second interaction at a time other than during the time window;
• use image processing to determine that the individual in the first interaction is the individual in the second interaction;
• access the memory to locate the at least one key word from the first interaction;
• and
• during the second interaction, cause a display of at least one key word on a display visible to the user, to thereby remind the user of subject matter of the first interaction.

A non-transitory computer-readable medium for use in a system employing a wearable image sensor pairable with a mobile communications device, the computer-readable medium containing instructions that when executed by at least one processor cause the at least one processor to perform steps, comprising:

• receiving from the wearable image sensor worn by a user a facial image of an individual with whom the user interacted in a first interaction during a time window;
• receiving sound data captured in a vicinity of the image sensor during the time window;
• processing the sound data to identify at least one key word in the sound data;
• storing in memory an association between the key word and the facial image;
• receiving from the wearable image sensor worn by a user another facial image of the individual during a second interaction at a time other than during the time window;
• using image processing to determine that the individual in the first interaction is the individual in the second interaction;
• accessing the memory to locate the at least one key word from the first interaction;
• and
• during the second interaction, presenting on a display visible to the user, the at least one key word, to thereby remind the user of subject matter of the first interaction.

A method for retrieving and displaying key words from prior conversations, the method being implemented by at least one processor of a wearable apparatus and comprising:

• receiving, from a wearable image sensor of the wearable apparatus, a facial image of an individual with whom a user of the wearable apparatus interacted in a first interaction during a time window;
• receiving sound data captured in a vicinity of the image sensor during at least a part of the time window;
• processing the sound data to identify at least one key word;
• storing in memory an association between the key word and the facial image;
• receiving, from the wearable image sensor, another facial image of the individual during a second interaction at a time other than during the time window;
• using image processing to determine that the individual in the first interaction is the individual in the second interaction;
• accessing the memory to locate the at least one key word from the first interaction;
• and
• during the second interaction, causing a display of at least one key word on a display visible to the user, to thereby remind the user of subject matter of the first interaction.
