Enables recognition of events within motion data including but not limited to motion capture data obtained from portable wireless motion capture elements such as visual markers and sensors, radio frequency identification tags and motion sensors within mobile device computer systems, or calculated based on analyzed movement associated with the same user, other user, historical user or group of users. Provides low power transmission of events. Greatly reduces storage for events such as a shot, move or swing of a player, a concussion of a player, boxer, rider or driver, or a heat stroke, hypothermia, seizure, asthma attack, epileptic attack. Events may be correlated with image(s) as captured from internal / external camera(s) or nanny cam, for example to enable saving video of the event, such as the first steps of a child, violent shaking events, sporting, military or other motion events including concussions, or falling events associated with an elderly person.

A system for flagging content in a chat session and providing enhancements in a transcript window. The system allows a user to set visible flags at the starting pointing of lines in the transcript area of the live chat window. Once one or more visual flags has been set in the transcript area, they are visually displayed in the transcript area visually indicating the lines they are associated with, and the live chat window is further modified to enable the user to navigate to the flags. When a flag is set, it is also added to a visually displayed list of such flags. The visually displayed flag list allows the user to select a flag and quickly navigate to a particular area within the chat transcript area that the user has deemed to be relatively significant. The flag list may be displayed at the top of the chat transcript within the transcript area itself, as a horizontal list of hot links, or in a new display region added to the live chat window, or in some other way. A “Next Flag” graphical button or the like may be displayed that allows the user to click on it to navigate to a next flag within the transcript area. When a chat transcript is saved, for example to a file or in an email document, the transcript area flags are saved, for example as HTML anchors.

Described herein are embodiments of systems, method, and computer programs for recommending an experience to a user. In one embodiment, a sensor takes measurements of affective response of the user while the user is exposed to token instances that are instantiations of visual tokens. An eye tracker measures the gaze of the user while the user is exposed to the token instances. A computer calculates, based on the measurements of affective response and measurements of the gaze, values of expected affective response of the user to exposure to instantiations of the visual tokens. These values are utilized to select an experience for the user, such that based on the values, an expected affective response of the user to exposure to token instances corresponding to the selected experience is more positive than an expected affective response of the user to exposure to token instances corresponding to other experiences.
