Abstract: Methods and arrangements involving portable devices are disclosed. One arrangement enables a content creator to select software with which that content should be rendered—assuring continuity between artistic intention and delivery. Another arrangement utilizes the camera of a smartphone to identify nearby subjects, and take actions based thereon. Others rely on near field chip (RFID) identification of objects, or on identification of audio streams (e.g., music, voice). Some of the detailed technologies concern improvements to the user interfaces associated with such devices. Others involve use of these devices in connection with shopping, text entry, sign language interpretation, and vision-based discovery. Still other improvements are architectural in nature, e.g., relating to evidence-based state machines, and blackboard systems. Yet other technologies concern use of linked data in portable devices—some of which exploit GPU capabilities. Still other technologies concern computational photography.

Abstract: Many of the detailed technologies are useful in enabling a smart phone to respond to a user's environment, e.g., so it can serve as an intuitive hearing and seeing device. A few of the detailed arrangements involve using radio base station SDR equipment (e.g., at a cell tower) to perform image recognition operations for phones; forecasting service needs from remote processors, and reserving such capacity in advance of use; delegating a remote execution task to a service provider chosen in a competitive process, such as by a reverse auction; using nearby processors, e.g.
