Audio content visualized by pico projection of text for interaction

A personal communication system comprises:

• a computing device;
• a camera system;
• a processing module;
• and
• a pico-projector, wherein the computing device is operable to:
• process digital data to produce an analog domain audio signal;
• perform audio to text conversion function on the analog domain audio signal to produce text data;
• and
• wherein, during the processing of the digital data:
• the camera system, when enabled, captures a physical gesture by a user of the computing device, wherein the physical gesture is regarding specific processing of the text data, wherein the specific processing includes one or more of:
• store the text data, store a portion of the text data, display the text data, and display a portion of the text data;
• when the specific processing includes displaying a portion of the text data:
• the processing module identifies the portion of the text data in accordance with the physical gesture regarding the specific processing of displaying the portion of the text data;
• and
• the pico-projector projects the portion of the text data onto a display area associated with the user.
