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. A haptic sensation can be output to the user of the local computer using a haptic device coupled to the local computer, where the haptic sensation is based at least in part on the received force information received from the remote computer.

Haptic sensations for tactile feedback computer interface devices. In one method, a tactile sensation is output during the interaction of a cursor and a graphical object, the tactile sensation being based on a periodic waveform and having a frequency correlated with a size of the graphical object interacted with the cursor. Another method includes receiving an indication of a position of a cursor, causing the cursor to snap to a graphical object, such as a line, when the cursor is within a predetermined distance so that the cursor can be moved along or within the graphical object, and enabling the output of a vibration sensation while the cursor is moved along or within the object. In another method, a tactile sensation includes a pop sensation that is a short, high magnitude sensation, and then a ringing sensation during or immediately after the output of the pop sensation and which can fade in magnitude over time.

Method and apparatus for controlling magnitude and frequency of vibrotactile sensations for haptic feedback devices. A haptic feedback device, such as a gamepad controller, mouse, remote control, etc., includes a housing, an actuator coupled to the housing, and a mass. In some embodiments, the mass can be oscillated by the actuator and a coupling between the actuator and the mass or between the mass and the housing has a variable compliance. Varying the compliance allows vibrotactile sensations having different magnitudes for a given drive signal to be output. In other embodiments, the actuator is a rotary actuator and the mass is an eccentric mass rotatable by the actuator about an axis of rotation. The eccentric mass has an eccentricity that can be varied relative to the axis of rotation while the mass is rotating. Varying the eccentricity allows vibrotactile sensations having different magnitudes for a given drive signal.

Embodiments related to the tactile enhancement of a computer input device are disclosed herein. In one disclosed embodiment, a method of making removable tactile-enhancing grips for a computer input device is disclosed. The method comprises heating a thermoplastic elastomeric sheet to a temperature at which the thermoplastic elastomeric sheet is capable of receiving and retaining an imprinted feature, pressing onto the thermoplastic elastomeric sheet a plate comprising a pattern, thereby embossing the pattern onto the thermoplastic elastomeric sheet, and cooling the thermoplastic elastomeric sheet to a temperature at which the pattern is retained in the thermoplastic elastomeric sheet. An adhesive layer is then formed on an opposite side of the thermoplastic elastomeric sheet as the pattern.
