Unobtrusive eye mounted display
An unobtrusive augmented reality (AR) system can be used to assist the wearer in every day interactions by projecting information from the contact lens display onto the retina of the wearer's eye. The unobtrusive augmented reality system includes a necklace and a contact lens display that are unobtrusive to the wearer and the wearer's surrounding environment. The necklace of the unobtrusive augmented reality system generates power and data for the contact lens displays. The necklace and contact lens display include conductive coils inductively coupled by a magnetic field. The inductive coupling allows data and power generated by the necklace to be transferred to the contact lens display. A projector in the contact lens display projects images generated from the data onto the retina of the wearers eye.
1. An augmented reality system comprising: a contact lens display capable of projecting images onto a user's retina; an audio input configured to receive audio that contains speech; and a processor coupled to the audio input, the processor configured to: receive the audio from the audio input; recognize speech in the audio; and convert the audio to text of the speech in a format suitable for transmission to the contact lens display, wherein the contact lens display projects the text onto the user's retina such that the user does not have to move their eye laterally to read displayed text, and wherein, for text that contains a plurality of words, the contact lens display sequentially projects the text onto the user's retina a few words at a time.
2. The augmented reality system of claim 1 , wherein the audio of the speech is in a first language, and the text of the speech is in a different second language.
3. The augmented reality system of claim 1 , wherein the contact lens display projects one word at a time.
4. The augmented reality system of claim 1 , wherein the contact lens display comprises a scleral contact lens that contains a femtoprojector.
5. The augmented reality system of claim 4 , wherein the scleral contact lens comprises an antenna for receiving the text, the antenna embedded between a front surface and a back surface of the scleral contact lens.
6. The augmented reality system of claim 1 , further comprising a mobile electronic device, wherein the mobile electronic device comprises a microphone and the processor, the microphone providing the audio to the audio input.
7. An augmented reality system comprising: a contact lens display capable of projecting images onto a user's retina; an audio input configured to receive audio that contains speech comprising a time sequence of words; and a processor coupled to the audio input, the processor configured to: receive the audio from the audio input; recognize speech in the audio; and convert the audio to text of the speech in a format suitable for transmission to the contact lens display, wherein the contact lens display sequentially projects groups of words from the time sequence of words onto the user's retina, each group of words comprising not more than three words at a time, and wherein the contact lens display projects the text onto the user's retina such that the user does not have to move their eye laterally to read displayed text.
