59 results about "Spatial memory" patented technology

In cognitive psychology and neuroscience, spatial memory is that part of the memory responsible for the recording of information about one's environment and spatial orientation. For example, a person's spatial memory is required in order to navigate around a familiar city, just as a rat's spatial memory is needed to learn the location of food at the end of a maze. It is often argued that in both humans and animals, spatial memories are summarized as a cognitive map. Spatial memory has representations within working, short-term memory and long-term memory. Research indicates that there are specific areas of the brain associated with spatial memory. Many methods are used for measuring spatial memory in children, adults, and animals.

Method and apparatus for providing a three-dimensional task gallery computer interface

The present invention provides a three-dimensional user interface for a computer system that allows a user to combine and store a group of windows as a task. The image of each task can be positioned within a three-dimensional environment such that the user may utilize spatial memory in order remember where a particular task is located. In further embodiments of the invention, the three-dimensional environment includes a stage, which is used to display the task with the current focus. When a user selects a new task in the gallery, the task is moved to the stage and given focus. If a previous task was on the stage, an image of the previous task is captured. This image is then moved into the task gallery away from the stage. This process allows users to switch between multiple window configurations with a simple action.

Methods, apparatus and data structures for providing a user interface to objects, the user interface exploiting spatial memory and visually indicating at least one object parameter

A graphical user interface in which object thumbnails are rendered in a three-dimensional environment and which exploits spatial memory. The objects may be moved, continuously, with a two-dimensional input device. Pop-up title bars may be rendered over active objects. Intelligent help may be provided to the user, as visual indicators, based on proximity clustering or based on matching algorithms. The simulated location of the object thumbnails in a direction orthogonal to the surface is based on function, such as a linear, polynomial, or exponential function for example, of one or more object properties, such as number of mouse clicks since selected, age, size, etc.

Dynamic thumbnails for document navigation

A “Spatial Navigator” provides a document navigation environment that leverages user spatial memory. Graphical thumbnail-type representations (“thumbnails”) provide scaled versions of entire documents. Changes to documents are immediately reflected in corresponding thumbnails. Similarly, document search results are highlighted in corresponding thumbnails. One or more dynamic document selection windows present arrangements of a plurality of these thumbnails for user selection and interaction. Each dynamic document selection window provides real-time inter-file navigation by allowing user selection and opening of documents, or any location or portion of a document, through user interaction with the corresponding thumbnail. Once a document is opened, intra-file navigation is enhanced by providing another scaled version of the entire document in a dynamic scrollbar adjacent to a primary document editing / viewing window. Selection of any point within this scrollbar-based thumbnail causes an immediate jump to the corresponding document location in the primary document editing / viewing window.

Systems and methods for displaying linked information in a sorted context

Techniques are presented for determining a first set of display elements, each display element associated with a first display characteristic. An interesting element in the first set of display elements is determined. A second set of elements related to the interesting element is determined. A third set of elements based on the first and second set of elements is determined using intersection, union, subtraction addition and other logical operations. A third set of elements not yet added to the element collection is determined. The elements in the third set are associated with a second or ghosted display characteristic. The elements in the third set are inserted within the sorted context of the visualization based on spatial distortion rules which help to preserve spatial memory cues in the visualization of the element collection.

Systems and methods for backward-compatible constant-time exception-protection memory

Embodiments of the invention provide a table-free technique for detecting all temporal and spatial memory access errors in programs supporting general pointers. Embodiments of the invention provide such error checking using constant-time operations. Embodiments of the invention rely on fat pointers, whose size is contained within standard scalar sizes (up to two words) so that atomic hardware support for operations upon the pointers is obtained along with meaningful casts in-between pointers and other scalars. Optimized compilation of code becomes possible since the scalarized-for-free encoded pointers get register allocated and manipulated. Backward compatibility is enabled by the scalar pointer sizes, with automatic support provided for encoding and decoding of fat pointers in place for interaction with unprotected code.
