A method of exchanging data comprises specifying in a first electronic device a recipient via perceptual addressing, and sending information from the first electronic device indicating an intent to conditionally communicate with the recipient only upon an expression of interest from the recipient in communicating with a user of the first electronic device. In a further example, a conditional message is sent from the first electronic device to the specified recipient electronic device such that the conditional message is visible to a recipient device user only upon the expression of interest from the recipient in communicating with a user of the first electronic device. |
