This invention relates to methods and apparatus for improving communications between humans and devices. The invention provides a method of modulating operation of a device, comprising: providing an attentive user interface for obtaining information about an attentive state of a user; and modulating operation of a device on the basis of the obtained information, wherein the operation that is modulated is initiated by the device. Preferably, the information about the user's attentive state is eye contact of the user with the device that is sensed by the attentive user interface.

Method and Apparatus for Communication Between Humans and Devices

In one embodiment of the invention, a method for controlling a robotic surgical tool is disclosed. The method for controlling a robotic surgical tool includes moving a monitor displaying an image of a robotic surgical tool; sensing motion of the monitor; and translating the sensed motion of the monitor into motion of the robotic surgical tool.

Controlling a robotic surgical tool with a display monitor

A method and information system for capturing signals, for processing signals, and for providing signals at least partially based on, or bearing correlation to, the captured signals is disclosed. The information system includes a signal input unit, a wireless communication unit, and an output unit. The signal input unit (preferably an optical signal unit) is constructed and is positionable to capture signals associated with an eye. The output unit is constructed to provide information based on the captured signals or to provide information as a function of the captured signals or in correlation with the captured signals.

Interactive data view and command system

Optimizing operation of a media player during rendering of media files. The invention includes authoring software to create a data structure and to populate the created data structure with obtained metadata. The invention also includes rendering software to retrieve the metadata from the data structure and to identify media files to render. In one embodiment, the invention is operable as part of a compressed media format having a set of small files containing metadata, menus, and playlists in a compiled binary format designed for playback on feature-rich personal computer media players as well as low cost media players.

Optimizing media player memory during rendering

Systems and methods are provided for discerning the intent of a device wearer primarily based on movements of the eyes. The system can be included within unobtrusive headwear that performs eye tracking and controls screen display. The system can also utilize remote eye tracking camera(s), remote displays and/or other ancillary inputs. Screen layout is optimized to facilitate the formation and reliable detection of rapid eye signals. The detection of eye signals is based on tracking physiological movements of the eye that are under voluntary control by the device wearer. The detection of eye signals results in actions that are compatible with wearable computing and a wide range of display devices.

Systems and methods for biomechanically-based eye signals for interacting with real and virtual objects

A first processor-based device (PBD), such as a personal computer functioning as a host and containing digital media files, may share a selected file with a second PBD. Media file-sharing may be facilitated by an automated technique including graphical user interfaces (GUIs). In one embodiment, when a device user wishes to transfer a file to another device, the user hovers the file over a particular desktop icon and drops it, causing it to be automatically transmitted to a corresponding destination. Optionally, in response to hovering, a software program automatically generates a GUI indicating potential destinations. The user then selects a destination, and the system automatically transfers the file to that destination. In another embodiment, media sharing can be initiated from a digital appliance, such as a digital picture frame, and a file can be sent to another PBD, such as another digital picture frame via an intermediary PBD.

User interface to facilitate exchanging files among processor-based devices

An electronic device may include a microdisplay in which a displayed image element may be selected by gazing upon it. An eye gaze detector may determine what the user is looking at at any given instance of time if the user looks at it for sufficient time. Once an image element is identified as being selected by being gazed upon, the screen display may be altered to change the appearance of the selected image element and the unselected image elements. For example, the selected image element may be brought into focus and other image elements may be blurred.

Microdisplay with eye gaze detection

A first type of processor-based device, such as a personal computer functioning as a host and containing digital media files, may wirelessly communicate with a second type of processor-based device or appliance, such as a digital picture frame (DPF). Upon request and/or at periodic intervals, the host may transmit menu items and/or media files to the DPF. Responsive to user choices entered at the DPF and transmitted to the host, the host may transmit further menu items and/or media files to the DPF. Methods of polling and registering one or more DPFs by a host, of retrieving media files by a host from the Internet satisfying user-specified search criteria, and of uploading media files from a DPF to a host, are also described, in addition to a network and a machine-accessible medium.

Network of disparate processor-based devices to exchange and display media files

A digital picture display system may operate through a wireless connection to a remote processor-based display. The system may operate in a portable and/or a fixed mode. In the portable mode, a portable display device may be wirelessly coupled to the processor-based system and may function using its own onboard battery source. In a fixed mode, the portable device may be plugged into a display station, which not only provides an AC power supply, but also aesthetically frames the display device, providing a picture framing function as well.

Docking digital picture displays

An embodiment of the invention is a method of generating a final exposure setting, including, (a) selecting one of a number of predetermined exposure settings as a current exposure setting for a solid state camera having a camera imager, (b) generating a captured scene by the camera imager using the current exposure setting, (c) selecting according to an automated search methodology another one of the exposure settings to be the current setting in response to the captured scene being underexposed or overexposed, and, (d) repeating (b) and (c) until the captured scene is neither underexposed or overexposed.
