Abstract: Augmented-reality systems provide additional information to users, beyond what they can normally perceive with their own senses. Embodiments of the invention establish “cover objects” having an identifiable visual appearance, and provide systems and infrastructure to deliver the additional information to multiple users via a live digital-camera image when each user directs his or her camera at the cover object. Different users may receive different additional information when scanning the same cover object at the same time, and a single user may receive different additional information when scanning the same cover object at different times. Methods and systems for accomplishing this are described, and a number of applications using the capabilities of such systems are suggested.

Abstract: When units of serialized input are analyzed by an engine or algorithm that provides a plurality of entry suggestions for competing or replacing a unit of the serialized input, one or more haptic effects can be identified and provided in conjunction with display, selection, or use of one or more of the entry suggestions to aid in the use of the engine or algorithm. The haptic effects can represent a confidence level with respect to one or more of the entry suggestions or may otherwise indicate the relative success of the engine/algorithm. For example, the serialized input may comprise characters input to a mobile or other device. The engine or algorithm may suggest words or phrases with varying degrees of confidence, with the confidence with respect to some or all of the suggestions communicated by use of haptic effects.
