73 results about "Visual capture" patented technology

In psychology, visual capture is the dominance of vision over other sense modalities in creating a percept. In this process, the visual senses influence the other parts of the somatosensory system, to result in a perceived environment that is not congruent with the actual stimuli. Through this phenomenon, the visual system is able to disregard what other information a different sensory system is conveying, and provide a logical explanation for whatever output the environment provides. Visual capture allows one to interpret the location of sound as well as the sensation of touch without actually relying on those stimuli but rather creating an output that allows the individual to perceive a coherent environment.

System and method for point of service payment acceptance via wireless communication

A system and method for remitting payment from a consumer's credit or stored value account by digital presentations of account information are described. A merchant may create one or more merchant account at a point-of-sale service site (“POS service site”) and associate one or more merchant portable computing devices (“MPCDs”) with one or more of the merchant accounts. Each MPCD may be configured to receive customer data from a customer via one of a visual capture and a wireless communication, such as a near field communication (“NFC”) or a machine-readable optical code. The customer data may be received from an NFC-capable physical token such as an EMV card, or a virtual token presented by a customer portable computing device (“CPCD”) using a NFC or a machine-readable optical code. Each MPCD may contain a point-of-sale payment application supplied by the POS service site that may capture data representative of a consumer account from the received customer data.
