Patent number: 10234944Abstract: A force feedback system provides components for use in a force feedback system including a host computer and a force feedback interface device. An architecture for a host computer allows multi-tasking application programs to interface with the force feedback device without conflicts. One embodiment of a force feedback device provides both relative position reporting and absolute position reporting to allow great flexibility. A different device embodiment provides relative position reporting device allowing maximum compatibility with existing software. Information such as ballistic parameters and screen size sent from the host to the force feedback device allow accurate mouse positions and graphical object positions to be determined in the force feedback environment. Force feedback effects and structures are further described, such as events and enclosures.Type: GrantFiled: April 15, 2016Date of Patent: March 19, 2019Assignee: IMMERSION CORPORATIONInventors: Adam C.

Patent number: 8838671Abstract: Force feedback is provided to a user of a client computer receiving information such as a web page over a network such as the World Wide Web from a server machine. The client machine has a force feedback interface device through which the user experiences physical force feedback. The web page may include force feedback information to provide authored force effects. Force feedback is correlated to web page objects by a force feedback program running on the client and based on input information from the interface device, the web page objects, and the force feedback information. Generic force effects can also be provided, which are applied uniformly at the client machine to all web page objects of a particular type as defined by user preferences at the client machine. A web page authoring interface is also described that includes the ability to add force sensations to a web page. The user may assign force effects to web page objects and immediately feel how the web page will feel to an end user.Type: GrantFiled: March 5, 2002Date of Patent: September 16, 2014Assignee: Immersion CorporationInventors: Evan F.

Patent number: 8717287Abstract: A design interface tool for designing force sensations for use with a host computer and haptic feedback interface device. A haptic feedback device communicates with a host computer that displays the interface tool. The user selects and characterizes force sensations using the interface tool, and a graphical representation of the characterized force sensation is displayed. The characterized force sensation is output to a user manipulatable object of the force feedback device so that the user can feel the designed force sensation The user can include multiple force sensations in a compound force sensation, where the compound sensation is graphically displayed to indicate the relative start times and duration of each of the force sensations. The user can also associate a sound with the force sensation, such that the sound is output in conjunction with the output of the force sensation.Type: GrantFiled: April 19, 2010Date of Patent: May 6, 2014Assignee: Immersion CorporationInventors: Dean C.

Patent number: 7843424Abstract: A design interface tool for designing force sensations for use with a host computer and force feedback interface device. A force feedback device is connected to a host computer that displays the interface tool. Input from a user is received in the interface to select a type of force sensation to be commanded by a host computer and output by a force feedback interface device. Input, such as parameters, is then received from the user which designs and defines physical characteristics of the selected force sensation. A graphical representation of the characterized force sensation is displayed on the host computer which provides a visual demonstration of a feel of the characterized force sensation so that the user can view an effect of parameters on said force sensation.Type: GrantFiled: April 10, 2006Date of Patent: November 30, 2010Assignee: Immersion CorporationInventors: Louis B.

Patent number: RE45884Abstract: A chat interface allowing a user to exchange haptic chat messages with other users in a chat session over a computer network. A chat interface can be displayed by a local computer and receives input data from a user of the local computer, such as text characters or speech input. The input data provides an outgoing chat message that can include sent force information. The outgoing chat message is sent to a remote computer that is connected to the local host computer via a computer network. The remote computer can display a chat interface and output a haptic sensation to a user of the remote computer based at least in part on the force information in the outgoing chat message. An incoming message from the remote computer can also be received at the chat interface, which may also include received force information. The incoming chat message is displayed on a display device to the user of the local computer.Type: GrantFiled: February 16, 2011Date of Patent: February 9, 2016Assignee: Immersion CorporationInventors: Evan F.
