A planar touch control is used to provide input to a computer and haptic feedback is provided thereto. A touch control includes a touch input device with a planar touch surface that inputs a position signal to a processor associated with the computer based on a location of user implemented contact on the touch surface. The computer can position or modify a cursor or image 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 via the touch surface.

There is provided a haptic feedback device and an electronic device having the same. The haptic feedback device includes a display panel receiving contact pressure applied thereto; an actuator generating vibrations so as to give different types of haptic feedback according to a change in the contact pressure applied to the display panel; a support plate supporting the actuator; a bonding portion provided between an end portion of the actuator in a lengthwise direction thereof and the support plate so as to fix the actuator to the support plate; and a vibration space expanding portion formed to be recessed in a portion of the support plate corresponding to the actuator.

A biaxial hinge having a rotating mechanism that realizes durability, a good tactile feedback, smaller size and more lightweight is provided for use in a notebook computer or a portable telephone that needs to be smaller and more lightweight. The biaxial hinge is constituted such that a rotating shaft support member is fixed to a rotational shaft support member, a rotation-side member is inserted and attached to the outer periphery of the rotating shaft member, and an opening / closing torque unit mechanism for opening and closing operations is disposed at the rotation-side member, wherein sliding friction torque and click torque are generated by the load produced by a coil spring between pressing members and the rotating shaft support member or a sliding member attached to the rotating shaft member. The rotating mechanism of the biaxial hinge of the present invention affords good durability, a good tactile feedback, and a reduction in size and weight. And, this rotating mechanism is applied to a portable telephone.

A vehicle control system uses a touchscreen display to displaying a graphical HMI and detect a contact point where touched by a user's finger. A haptic texture system has an electrode disposed across the touchscreen display and a signal generator generating an oscillating signal to produce a potential difference between the finger and the electrode resulting in a corresponding perceived texture as the finger slides over the touchscreen. A control circuit is configured to set at least a frequency or amplitude of the oscillating signal to vary the perceived texture according to first and second modes while navigating the graphical HMI. The first mode uses a localized texture mapping defined by respective feature icon selection regions on the touchscreen display. The second mode uses a status texture mapping relating the perceived texture to each potential adjustment setting available for a feature icon that has been selected using the first mode.
