Smartphone-Based Methods and Systems

Abstract

Arrangements involving portable devices (e.g., smartphones and tablet computers) are disclosed. One arrangement enables a content creator to select software with which that creator's content should be rendered—assuring continuity between artistic intention and delivery. Another utilizes a device camera 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 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. A great variety of other features and arrangements are also detailed.

AI Technical Summary

Benefits of technology

[0139]The front-facing camera on a smartphone can be used to speed text entry, in a gaze-tracking mode.

[0765]Although reference was made to GPUs, this term is meant to include any device that includes plural hardware cores operable simultaneously. Intel, for example, uses the term “Many Integrated Core,” or Intel MIC, to indicate such class of device. Most contemporary GPUs have instruction sets that are optimized for graphics processing. The Apple iPhone 4 device uses a PowerVR SGX 535 GPU (included in a system-on-a-chip configuration, with other devices). Most such devices include, in their instruction sets, instructions that are tailored to work with 3- or 4-plane imagery, to accelerate the building of images in a frame buffer intended for output to a display. For example, many instructions take data triples as input, and provide data triples as output. Other instructions facilitate operating on spatial neighborhoods of data values in stored image frames.

Problems solved by technology

This varied, interrelated subject matter does not lend itself to a straightforward presentation.

It is difficult for apps to gain traction in this crowded marketplace.

Both approaches, however, were established when the app market was much smaller, and have not scaled well.
