Embodiment Construction
[0049] like figure 1 As shown, the structure of the tactile reproduction device fused by any one or more of electrostatic force, mechanical vibration, and air pressure film includes:
[0050] (1) Positioning unit and interaction unit 11: The touch display screen reproduced by tactile is used as the positioning unit and the interaction unit, which realizes the “two screens in one” in which the touch display screen and the touch positioning screen are combined into a touch display screen with tactile reproduction. ” technology, the touch display screen of tactile reproduction is composed of a device for realizing positioning function, two piezoelectric ceramic sheets 14 and an electrostatic force touch screen, and six vibration motors 16 are fixed on the back 10 of the tablet 12, such as figure 2 It can not only realize the positioning function, track the position coordinates of the finger in real time, and send the coordinate information to the processing unit; it can also re...

The invention relates to a tactile feedback rendering method and device for a virtual knob of a vehicle-mounted terminal interface, and belongs to the field of automotive electronics, virtual reality and human-computer interaction. After finger position information when a user interacts with a vehicle-mounted terminal interface is obtained, a touch representation device fusing any one or more modes of electrostatic force, mechanical vibration and air pressure film is adopted, the gesture category is judged based on a coordinate transformation method, and the angle and the angular speed of a finger rotating knob are calculated; an angular velocity-signal frequency mapping model is established, the frictional resistance between the finger and the screen is changed based on the rotation angular velocity, and the effect that the tactile feedback is changed along with different rotation angular velocities is achieved. By means of the touch effect, a driver can be prompted and confirmed when operating the rotary knob in a bumpy environment, mistaken touch or missing of a target point is prevented, blind control is achieved during driving, the burden of the visual mode and the auditory mode of the driver is relieved, the interactive experience of the driver is enhanced, and driving safety is improved.
Description
technical field [0001] The invention belongs to the fields of automotive electronics, virtual reality and human-computer interaction, and in particular relates to a tactile feedback rendering method and device for a virtual knob of an in-vehicle terminal interface. Background technique [0002] Cars typically have purely physical controls like knobs, buttons, and sliders, but now that vehicle dashboards are rapidly transforming into computer interfaces, the concept of car interiors has undergone a subversive shift. The automotive industry has begun to install touch displays on car dashboards and center consoles to reduce the need for physical controls such as buttons and knobs, and to design more configurable and richly beautiful car interiors, so the way drivers operate is changing. This presents a challenge for drivers, as there are no on-screen prompts that would make traditional controls such as clicking buttons and turning knobs easy to operate. Traditional in-vehicle ...
