Abstract
Techniques and mechanisms for determining a level of accommodation to be provided by an eye-mountable device (EMD) for a user viewing a 3D stereoscopic display. In one embodiment, the EMD in disposed in or on an eye of the user, and an angle of vergence between the user's eyes is detected. Based on the angle of vergence, the EMD provides a level of accommodation that results in the user having a blurred viewing of an object in the stereoscopic display. The blur induces the user to change the accommodation provided by the eye on which, or in which, the EMD is disposed. Inducing the user to perform such a change in the eye's accommodation more closely approximates what the user would do when viewing real world physical objects. This tends to result in a better viewing experience by the user. In another embodiment, the angle of vergence is detected based on exposure of the EMD to a magnetic field.
