A system and method is disclosed for recommending items to individual users using a combination of clustering decision trees and frequency-based term mapping. The system and method of the present invention is configured to receive data based on user action, such as television remote control activity, or computer keyboard entry, and when a new item data is made available from sources such as television program guides, movie databases, deliverers of advertising data, on-line auction web sites, and electronic mail servers, the system and method analytically breaks down the new item data, compares it to ascertained attributes of item data that a user liked in the past, and produces numeric ranking of the new item data dynamically, and without subsequent user input, or data manipulation by item data deliverers, and is tailored to each individual user. A embodiment is disclosed for learning user interests based on user actions and then applying the learned knowledge to rank, recommend, and / or filter items, such as e-mail spam, based on the level of interest to a user. The embodiment may be used for automated personalized information learning, recommendation, and / or filtering systems in applications such as television programming, web-based auctions, targeted advertising, and electronic mail filtering. The embodiment may be structured to generate item descriptions, learn items of interest, learn terms that effectively describe the items, cluster similar items in a compact data structure, and then use the structure to rank new offerings. Embodiments of the present invention include, by way of non-limiting example: allowing the assignment of rank scores to candidate items so one can be recommended over another, building decision trees incrementally using unsupervised learning to cluster examples into categories automatically, consistency with “edge” (thick client) computing whereby certain data structures and most of the processing are localized to the set-top box or local PC, the ability to learn content attributes automatically on-the-fly, and the ability to store user preferences in opaque local data structures and are not easily traceable to individual users.

An improved opaque computer keyboard cover (10) which covers only the three- or four alpha-numeric rows of the keyboard (12). Function and format keys (12) are not covered which provides a one-size-fits-all design. This configuration eliminates the need to order from 3000 various keyboard cover sizes. This cover is for use in keyboarding instruction and prevents peeking to accelerate user memorization. This cover can also be imprinted with a language option layout or Dvorak keyboard layout thus fully conforming the keyboard layout to one of the 60 or so languages available in the computer operating system keyboard preference options.

This invention is an ergonomic method and apparatus for integrating the operation of computer keyboards and cursor control devices. It employs hand location detection to determine when the mouse hand is absent from its keyboard typing position or is present at the mouse. A detector output automatically transforms the functions of a set of keyboard keys lying under the non-mouse hand from their original actions into new actions which can include mouse clicks, keyboard shortcuts and macros. These keys usually include the home keys (a s d f, or j k l ;). The new functions are preprogrammed into this set of keys at an inactive level, and do not affect actions unless the hand position sensor detects that the mouse hand is absent from its keyboard typing position or is present at the mouse. This invention allows the non-mouse hand to actuate clicks at the keyboard by using the home keys as click switches, and also makes it possible for the non-mouse hand to type, with a single keystroke, keyboard shortcuts not normally available to it. When the mouse hand returns to the keyboard the keys automatically revert to their default functions. This method increases working speed, reduces the number of trips back and forth between keyboard and mouse, and relieves stress on the mouse hand. It is of special value to persons with carpal tunnel syndrome or Repetitive Strain Injuries. Detection of hand position or location is accomplished by sensors at the keyboard and / or at the pointing device, or by software detection of any data output from the mouse (movement or click) or from any keypress on the mouse side of the keyboard. This invention can be embodied solely as software, as firmware in an external device or keyboard, or as any combination of software and firmware. It essentially converts the non-mouse side of the keyboard into single-key macros: mouse buttons, tool selection keys, and special function keys. It can also be used to temporarily assign an alternate set of actions to mouse motion, mouse buttons and scrolling devices. Optionally this invention includes a floating on-screen palette which serves as an indicator of transformation and provides a map of the new functions. With simultaneous transformation of both a keyset and its corresponding palette, the palette always displays the new functions in the same geometric pattern as the actual layout of the new functions on the keyboard. This enables eye-to-hand pattern transfer for intuitive tool selection via the keyboard without using the mouse.

A computer keyboard has a grid of conductors forming a plurality of intersections, with force-sensitive resistor (FSR) elements located between the conductors at the intersections. A plurality of keys are located above the intersections and exert force on the conductors and FSR elements during key presses. A resistor network sub-circuit is connected to some of the conductors, and is switchable between low and high resistance values. An Analog to Digital Converter (ADC) is coupled to the resistor network sub-circuit. A microprocessor grounds a conductor and tests another conductor for a threshold voltage level while the resistor network is switched to the high resistance value. The microprocessor switches the resistor network to the low resistance value upon detecting the threshold voltage level and subsequently receives from the ADC a digital value of a voltage on the tested conductor.

3D music visualization process employing a novel method of real-time reconfigurable control of 3D geometry and texture, employing blended control combinations of software oscillators, computer keyboard and mouse, audio spectrum, control recordings and MIDI protocol. The method includes a programmable visual attack, decay, sustain and release (V-ADSR) transfer function applicable to all degrees of freedom of 3D output parameters, enhancing even binary control inputs with continuous and aesthetic spatio-temporal symmetries of behavior. A “Scene Nodes Graph” for authoring content acts as a hierarchical, object-oriented graphical interpreter for defining 3D models and their textures, as well as flexibly defining how the control source blend(s) are connected or “Routed” to those objects. An “Auto-Builder” simplifies Scene construction by auto-inserting and auto-routing Scene Objects. The Scene Nodes Graph also includes means for real-time modification of the control scheme structure itself, and supports direct real-time keyboard / mouse adjustment to all parameters of all input control sources and all output objects. Dynamic control schemes are also supported such as control sources modifying the Routing and parameters of other control sources. Auto-scene-creator feature allows automatic scene creation by exploiting the maximum threshold of visualizer set of variables to create a nearly infinite set of scenes. A Realtime-Network-Updater feature allows multiple local and / or remote users to simultaneously co-create scenes in real-time and effect the changes in a networked community environment where in universal variables are interactively updated in real-time thus enabling scene co-creation in a global environment. In terms of the human subjective perception, the method creates, enhances and amplifies multiple forms of both passive and interactive synesthesia. The method utilizes transfer functions providing multiple forms of applied symmetry in the control feedback process yielding an increased level of perceived visual harmony and beauty. The method enables a substantially increased number of both passive and human-interactive interpenetrating control / feedback processes that may be simultaneously employed within the same audio-visual perceptual space, while maintaining distinct recognition of each, and reducing the threshold of human ergonomic effort required to distinguish them even when so coexistent. Taken together, these novel features of the invention can be employed (by means of considered Scene content construction) to realize an increased density of “orthogonal features” in cybernetic multimedia content. This furthermore increases the maximum number of human players who can simultaneously participate in shared interactive music visualization content while each still retaining relatively clear perception of their own control / feedback parameters.
