A motion controlled handheld device includes a display having a viewable surface and operable to generate an image and a gesture database maintaining a plurality of gestures. Each gesture is defined by a motion of the device with respect to a first position of the device. The gestures comprise symbol gestures each corresponding to a character from a preexisting character set. The device includes an application database maintaining at least one application and a gesture mapping database comprising a gesture input map for the application. The gesture input map comprises mappings of the symbol gestures to corresponding inputs for the application. The device includes a motion detection module operable to detect motion of the handheld device within three dimensions and to identify components of the motion in relation to the viewable surface. The device also includes a control module operable to load the application, to track movement of the handheld device using the motion detection module, to compare the tracked movement against the symbol gestures to identify a matching symbol gesture, to identify, using the gesture input map, the corresponding input mapped to the matching symbol gesture, and to provide the corresponding input to the application.

Gesture based user interface supporting preexisting symbols

A method of using a user model with salience includes providing content to a user through a user interface. The method also includes receiving physiological data corresponding to a physiological response of the user as the user interacts with the content. The method may also include determining a salience score for the content based at least in part on the physiological response of the user, and updating a user model with the salience score.

User modeling with salience

According to an aspect of an embodiment, a system of using an extensible language to represent storage metadata includes a computer-readable storage medium and a processing device. The computer-readable storage medium may have stored thereon storage metadata. The processing device may be configured to write the storage metadata to the computer-readable storage medium in an extensible language format. The processing device may also be configured to manipulate the storage metadata in the extensible language format. The processing device may also be configured to transfer the storage metadata in the extensible language format.

Extensible method and system for storage metadata

According to one embodiment of the present invention, a method for selecting metadata for sensor data streams may be provided. The method may include receiving a first sensor data stream associated with a user. The first data stream may be generated by one or more sensors co-located with the user. A plurality of tags that are each associated with one or more sensor value ranges may be accessed. A first tag may be selected from the plurality of tags according to a relationship between the first sensor data stream and the one or more sensor value ranges associated with the first tag. The method may further include facilitating reporting of the first tag.

Selecting metadata for sensor data streams

According to an aspect of an embodiment, a method of measuring physiological adaptability of a subject is described. The method may include receiving, from a first sensor, a first data signal indicating a first biological function of the subject. The method may also include receiving, from a second sensor, a second data signal indicating a second biological function of the subject. The method may also include calculating an adaptability of the subject based on the first data signal and the second data signal. The method may also include reporting the calculated adaptability.

Physiological adaptability system with multiple sensors

In one embodiment, modeling topics includes accessing a corpus comprising documents that include words. Words of a document are selected as keywords of the document. The documents are clustered according to the keywords to yield clusters, where each cluster corresponds to a topic. A statistical distribution is generated for a cluster from words of the documents of the cluster. A topic is modeled using the statistical distribution generated for the cluster corresponding to the topic.

Modeling topics using statistical distributions

A method of determining stress includes receiving a data signal including multiple consecutive RR intervals of a subject. The method may also include calculating heart rate variability (HRV) data for the subject from the data signal. The method may also include calculating an RR integral average (RRIA) from the HRV data, the RRIA indicating a stress level of the subject.

Stress model based on RR integral average

A method of operating an image-sensing device includes detecting a trigger. The method also includes, in response to detecting the trigger, changing an operating mode of the image-sensing device from a first operating mode having a first spatial resolution and a first temporal resolution to a second operating mode having a second spatial resolution and a second temporal resolution. The second spatial resolution may be lower than the first spatial resolution and the second temporal resolution may be higher than the first temporal resolution. The method may also include capturing video data in the second operating mode, the video data having the second spatial resolution and the second temporal resolution.

Reduction of spatial resolution for temporal resolution

In a method embodiment, a method for automatically editing data recorded during a videoconference includes accessing a plurality of video data streams. Each video data stream records a view of at least one of a plurality of human participants of the videoconference. The view recorded by each video data stream is different from the view recorded by each other video data stream. The method further includes determining, using one or more processors executing logic, that one of the plurality of video data streams recorded a view of a first one of the plurality of participants while the first one of the plurality of participants made a first statement. In addition the method includes determining, using one or more processors executing logic, that one of the plurality of video data streams recorded a view of a second one of the plurality of participants while the second one of the plurality of participants made a second statement after the first one of the plurality of participants made the first statement. An edited video data stream is generated using the plurality of video data streams. The edited video data stream comprises a transition that switches from the view of the first one of the plurality of participants to the view of the second one of the plurality of participants. The transition is timed such that when the edited video data stream is played the transition occurs before the commencement of the second statement.

System and method for editing recorded videoconference data

In particular embodiments, a method includes accessing data streams from a first group of physiological sensors monitoring a person, a second group of deconfounding sensors monitoring the person, and a third group of sensors monitoring a stressor, analyzing data sets collected from the person when the person is exposed and not exposed to the stressor, and determining a current stress factor for the stressor with respect to the person based on the analysis.
