Deliberative and reactive processing are combined to process multi-modal inputs and direct movements and speech of a synthetic character that operates as an interface between a user and a piece of equipment. The synthetic character is constructed as an ally, working with and helping the user learn and operate the equipment. The synthetic character interacts with both a virtual space where the character is displayed, and a physical space (domain) that includes the user. Real-time reactive processing provides lifelike and engaging responses to user queries and conversations. Deliberative processing provides responses to inputs that require more processing time (deep linguistic processing, for example). Knowledge bases are maintained for both dynamic (discourse model, for example) and static (e.g., knowledge about the domain or discourse plans) information types. A rule based system is utilized against the knowledge bases and selected inputs from said user to determine input meanings, and follow a predetermined discourse plan.

An electronic notebook assigns properties to digital ink of note marks and keywords to digital pages. The properties indicate the type of note mark and the keywords indicate general content of the note marks on a digital page. The notebook also synchronizes audio data with the note marks and permits audio highlighting. The electronic notebook provides an updatable database of note marks and audio that is capable of being searched based on the properties, keywords, and audio highlights.

System for capturing and retrieving audio data and corresponding

When dynamically grouping a plurality of graphic objects, such as displayed on a graphic input display apparatus, a cluster tree is formed for the plurality of graphic objects. The cluster tree is based on a plurality of different types of distance measures. These include a time distance and a spatial distance. These distances are combined to form a distance metric indicting a distance between a pair of the graphic objects. Each level of the cluster tree defines a new cluster of the graphic objects. At least one of the graphic objects is selected. The different cluster levels of the cluster tree containing the selected graphic object are displayable. The displayed cluster of the graphic objects can be modified to increase or decrease the cluster level of the cluster containing the selected graphic object.
