Methods and systems for textures and other spatial sensations for a relative haptic interface device are described. One embodiment includes a method comprising the steps of receiving a signal from a sensor, the sensor signal associated with a change in a position of a haptic feedback device, transmitting sensor data to a host processor, the sensor data associated with the sensor signal, receiving force information from the host processor, the force information comprising a texture sensation having at least one parameter describing at least one force to be output based at least in part on an interaction of a graphical object with a texture field, the force information further comprising at least one characteristic of the texture sensation, parsing the force information, storing the at least one characteristic, and determining when to output the at least one force based at least in part on the interaction.

Directional haptic feedback provided in a haptic feedback interface device. An interface device includes at least two actuator assemblies, which each include a moving inertial mass. A single control signal provided to the actuator assemblies at different magnitudes provides directional inertial sensations felt by the user. A greater magnitude waveform can be applied to one actuator to provide a sensation having a direction approximately corresponding to a position of that actuator in the housing. In another embodiment, the actuator assemblies each include a rotary inertial mass and the control signals have different duty cycles to provide directional sensations. For power-consumption efficiency, the control signals can be interlaced or pulsed at a different frequency and duty cycle to reduce average power requirements.

An interface device and method for providing enhanced cursor control with force feedback. A force feedback interface device includes a manipulandum, such as a mouse, that is moveable in a local workspace. The device is coupled to a host computer that displays a cursor in a graphical environment, such as a GUI, on a display screen. An interior region and a border region in the local workspace is defined. One mapping of device movement to cursor movement is used for the interior region, and a different mapping is used for the border region. Mapping methods include ballistics, absolute, linear, rate control, and variable absolute. Rate control embodiments can be single axis or dual axis. In one embodiment, when the mouse moves from the interior region to the border region, the mapping providing the greater cursor velocity is used to better conserve device workspace in the direction of travel and to decrease any sense of mapping mode change to the user. Other features include an autocentering function for reducing offset between local and host frames.

A low-cost tactile feedback mouse device for providing haptic feedback to a user for enhancing interactions and manipulations in a graphical environment provided by a computer. The mouse device includes a sensor device able to detect the movement of the mouse in the planar workspace. An actuator is coupled to the housing of the mouse and applies an inertial force in a particular degree of freedom, preferably along an axis perpendicular to the planar workspace, where the inertial force is transmitted through the housing to the user. The actuator outputs the inertial force preferably by linearly moving an inertial mass along the Z-axis. The output force is correlated with interaction of a controlled graphical object, such as a cursor, with other graphical objects in a graphical environment displayed by the host computer. The inertial force can be a pulse, vibration, texture force, or other type of force.

A flexure mechanism for an interface device that interfaces a user with a computer system. An interface device includes a manipulandum physically contacted by the user. A five-bar closed-loop mechanism is coupled to the manipulandum to provide two rotary degrees of freedom to the manipulandum. The mechanism includes members coupled to each other by flexible couplings allowing rotation of the members. In preferred embodiments, four or five of the members are coupled together by flexible couplings that allow bending, thereby forming a unitary piece, where the couplings are oriented along axes of rotation of the mechanism. A senor senses a position of the manipulandum outputs a sensor signal, and in some embodiments actuators are coupled to the mechanism to output a force to the manipulandum in particular degrees of freedom. The manipulandum can be a joystick handle or portion of a sphere, where the device in one embodiment can be a handheld gamepad or similar controller.

The present invention provides a control knob on a device that allows a user to control functions of the device. In one embodiment, the knob is rotatable in a rotary degree of freedom and moveable in at least one transverse direction approximately perpendicular to the axis. An actuator is coupled to the knob to output a force in the rotary degree of freedom about the axis, thus providing force feedback. In a different embodiment, the knob is provided with force feedback in a rotary degree of freedom about an axis and is also moveable in a linear degree of freedom approximately parallel to the axis, allowing the knob to be pushed and/or pulled by the user. The device controlled by the knob can be a variety of types of devices, such as an audio device, video device, etc. The device can also include a display providing an image updated in response to manipulation of the knob. Detent forces can be provided for the knob by overlapping and adjusting ranges of closely-spaced detents in the rotary degree of freedom of the knob.

A haptic feedback planar touch control used to provide input to a computer. A touch input device includes a planar touch surface that inputs a position signal to a processor of the computer based on a location of user contact on the touch surface. The computer can position a cursor in a displayed graphical environment based at least in part on the position signal, or perform a different function. At least one actuator is also coupled to the touch input device and outputs a force to provide a haptic sensation to the user contacting the touch surface. The touch input device can be a touchpad separate from the computer's display screen, or can be a touch screen. Output haptic sensations on the touch input device can include pulses, vibrations, and spatial textures. The touch input device can include multiple different regions to control different computer functions.

Methods and Apparatus for enabling groups of patrons of localized physical establishments, such as restaurants and retail stores, to collaboratively select the sequence of musical media for public play. Some embodiments comprise receiving, at a centralized media server, a plurality of media request over a network from a plurality of separate personal portable computing devices, such as mobile phones. Each media request may comprise a media identifier, an establishment identifier and a customer identifier. In response to receiving such media requests, the centralized media server updates a listing of media files pending for play within a localized physical establishment associated with the establishment identifier. The centralized server also provides messaging functions, returning information to the portable computing devices of participating patrons, the information including for example, textual song dedications, song title and artist information, playlist lengths, and song popularity information.

A system provides a first person video depiction of a planned travel route from a designated start location to a designated destination location in response to a user's travel planning request. A user interface receives a start location and a destination location for the travel route from a user. A routing component plans the travel route based between the start location and the destination location. A first person image database stores still images associated with locations between the start location and the destination location. The still images display first-person photographic imagery in a driving direction of the travel route. A video generator generates high-speed video media depicting at least a portion of the travel route from the start location to the destination location along a planned travel path. The video media is generated by sequencing a series of the still images associated with locations between the start location and the destination location. A display monitor displays the high-speed video media to the user.
