Determinations of Characteristics from Biometric Signals

A method, comprising:

• measuring a first biometric signal and a second biometric signal from a user of a head-mounted display;
• generating a first latent space representation based on the first biometric signal;
• generating a second latent space representation based on the second biometric signal;
• weighting the first latent space representation and the second latent space representation based on correlations among latent space representations;
• determining a characteristic of the user based on the weighted first and second latent space representations;
• modifying audio or video content based on the determined characteristic;
• and
• delivering the modified audio or video content to the user of the head-mounted display.

A non-transitory computer-readable medium comprising instructions that, when executed by a processor, cause the processor to:

• generate a first latent space representation indicative of a characteristic of a user based on a first signal from a first biometric sensor;
• generate a second latent space representation indicative of the characteristic of a user based on a second signal from a second biometric sensor;
• generate a third latent space representation indicative of the characteristic of a user based on a third signal from a third biometric sensor calculate correlations between the first, second, and third soft latent space representations;
• weight each of the first, second, and third latent space representations based on the correlations of that latent space representation with the other latent space representations;
• and
• determine the characteristic of a user based on the weighted first, second, and third latent space representations.
