• an interface device comprising a smart surface with haptic feedback to a passenger.
• an armrest keyboard for providing an interface with capacitive haptic feedback for a user in an automotive setting, comprising an interactive rectangular surface comprising a haptic-feedback layer, a capacitive touch sensitive layer and a display; an armrest, wherein the armrest and the interactive surface are rotatably coupled; and an orientation sensor for detecting the orientation of the interactive surface in respect of the armrest; an electronic data processor configured to drive the haptic-feedback layer to provide a haptic-feedback; display a first keyboard in the display of the interactive surface when the orientation sensor indicates that the interactive surface and the armrest are oriented perpendicularly, and display a second keyboard in the display of the interactive surface when the orientation sensor indicates that the interactive surface and the armrest are oriented parallelly; wherein the second keyboard is more compact than the first keyboard and an operation method thereof.
• the present disclosure relates to a capacitive haptic feedback surface, herein called smart surface comprising, at least, 4 or 5 layers.
• the first, top-most layer is an insulative layer, applied to a transparent and conductive electrode sheet layer, which, when charged with an electric current and when in contact with the human skin, produces a frictional stimulus by controlling the electric current.
• These two layers are, in turn, applied to a capacitive-based touch sensitive layer.
• Below this layer rests another layer fitted with LED lights, which can produce strong enough lights to be visible through the previous layer, depending on the material of which said layer is made out of (this layer is optional).
• the fifth and final layer is composed of vibrotactile actuators, which can produce vibrations with enough frequency and amplitude for them to be felt by users while interacting with the top-most layer.
• Haptic feedback in devices and surfaces has commonly been achieved through vibrotactile stimuli, generated from mechanical actuators (e.g., EP3582074A1). More recently, haptic technologies have emerged that make use of other actuation types, such as electro vibration, to generate other types of tactile feedback beyond just vibrations (e.g., US10768749B2).
• the technology for creating richer display and surface interactions is available, by delivering different haptic feedback sensations, such as different texture sensations or different vibrations, to users while they interact with the display surface with their fingers. Richer interactions, in the present disclosure, refers to interactions that provide more feedback to users, instead of the usual sensation of just touching a surface.
• Richer interactions in the present disclosure, refers to interactions that provide more feedback to users, instead of the usual sensation of just touching a surface.
• any control commands such as increasing or decreasing the strength of an overhead light
• the software of the centre stack display device would have to be processed by the software of the centre stack display device, although the keyboard area could have some shortcuts associated with some simple actions such as this light control, or media volume control, for example, like it is currently found on most computer keyboards.
• the smart surface can be used to control those and any other parts. It is only a matter of having a controller which, upon sensing input on the smart surface, is able to actuate (directly or indirectly) on those parts.
• writing from a comfortable position on a virtual keyboard presented on the center stack display is difficult to achieve, since it requires passenger to bend forward on their seat, to stretch their arm(s), or both at the same time, which quickly becomes uncomfortable to maintain. Additionally, interactions with such virtual keyboards do not normally transmit any haptic feedback to passenger, making the writing process less intuitive.
• level 5 of autonomous vehicles i.e., in full automation
• concerns regarding driver distraction are no longer present, as the task of driving the vehicle is taken up by the vehicle itself, and the driver becomes just another passenger in the vehicle. Therefore, more control and interface elements can be added to each seat's armrest, so that passengers can access these controls from a comfortable position of their choosing, and without the interaction with said controls compromising their performance while driving the vehicle, as could occur if this was implemented on non- autonomous vehicles due to the increase of interactable elements possibly distracting the driver while trying to interact with them.
• said elements no longer need to be simple nobs, switches or on/off buttons, but instead can be more complex and useful controls and interfaces.
• other technologies such as haptic feedback surfaces, can be used to increase the passenger experience and engagement of passenger with these elements, contributing to a more pleasurable and/or useful commute.
• the present disclosure improves the driving safety, e.g., by providing haptic feedback of proximity to an obstacle while parking.
• the present disclosure is employable in level 5 autonomous vehicles.
• this smart surface can be employed as the interactive surface interface of a device to which it is not physically connected, e.g., touch surface interface communicating wirelessly with a display device in close proximity.
• the capacitive-based touch sensitive layer can be made of a variety of materials, depending on the intended use case and aesthetic appeal.
• the capacitive-based touch sensitive layer is made of translucent plastic - interactive surface interface for an external device with LED lights underneath it.
• the smart surface can generate both frictional and vibrotactile haptic sensations.
• frictional haptic sensations are generated thanks to the insulative and conductive layers, which allow for friction between the smart surface and the passenger's skin to be modulated through electrostatic actuation, while the skin is in motion.
• vibrotactile haptic sensations are generated thanks to the vibrotactile actuators, which can generate vibrations strong enough (e.g., 65Hz to 500Hz) to be felt through the passenger's skin, either stationary or in motion, when in direct contact with the smart surface.
• haptic feedback sensations when the smart surface is used as the interactive interface for an external device, haptic feedback sensations, programmed/controlled by the external device's software, can be generated on it, as long as the haptic actuation technology that is present on the smart surface is both capable of interpreting the software's information and of generating such sensations.
• the external device's software sends a command to the smart surface, requesting that it generates haptic and/or thermal feedback sensations on the surface layer
• the command technology/software found on the smart layer should be capable of differentiating between these types of actuations, delegating the request to the actuation technology that controls the actuators capable of generating said feedback.
• the capacitive and/or haptic feedback sensations of the smart surface are controlled by an external device which can be the same device that the smart surface is controlling (e.g., center stack) or other.
• the armrest keyboard comprises a 7" display, 7 mm thick, powered through a socket provided by the vehicle specifically for the device, communication with the vehicle via ethernet, and with user devices via Wi-Fi.
• the present disclosure is equipped on a portion of the surface of the vehicle seat's armrest, where it acts as an external interactive surface interface for the centre stack display device, in the form of a keyboard.
• the seat's armrest is part of a train carriage, airplane fuselage or other passenger compartment that have seats with armrests.
• a full haptic feedback keyboard surface actuated through electro vibration and/or vibrotactile actuation, which can be activated by the passenger and accessed on the vehicle seat armrest smart surface.
• LED lights integrated on their own layer between the capacitive-based touch sensitive layer and the layer of vibrotactile actuators, light up when the keyboard is in use, indicating the location of each specific key on the keyboard. The light from these LED lights should be strong enough to be seen through the capacitive-based touch sensitive layer, which, in turn, should be made of a material, or have a thin enough thickness, that allows for the lights to be clearly visible.
• the capacitive surface can be made of a material that allows for the LED light to pass through, which can be dependent on how thick said surface is (e.g., certain types of wood can let light pass through when it's thin enough).
• passenger can use this keyboard to facilitate and speed up their performance on tasks that involve writing, be it for entertainment, educational, or professional purposes, while sitting comfortably inside the vehicle during their commutes, keeping a comfortable posture.
• the armrest smart surface is embedded on a movable platform which, at the passenger's behest, can be switched into one of two positions, either placed directly on top of the full armrest structure, at the passenger's side, or it can be slid on top of the full armrest structure until it is set horizontally in front of the passenger.
• the movable platform's apparatus proceeds to move to the other position.
• This movable platform is placed between the armrest smart surface and the remaining structure of the armrest. This movable platform is connected to the middle and tail-right end of the armrest smart surface.
• the location where the movable platform connects to the armrest smart surface's middle portion is horizontally curved in its design.
• the movable platform moves over the length of the armrest structure, until it reaches the front end of it.
• it is locked in placed, and the movable platform component that is connected to the armrest smart surface's tail-right end begins to move inwards towards the middle portion.
• the armrest smart surface slides atop the middle portion of the movable platform, curving inwards instead of moving fully forward, until it reaches the "full” or “extended” mode (as seen in Figure 1). If, when the "switch” button is pressed, and the armrest smart surface is in “full” or “extended” mode, the reverse of this process occurs, and instead of the movable platform's component that is connected to the armrest smart surface's tail-right end sliding towards the middle portion of the movable platform, it instead slides away from said portion.
• the assembly of this structure to a base/normal armrest can be plug and play, can come pre-installed on it, or it can be installed by a knowledgeable person. For the smart surface's components to be powered, it should be connected to any of the vehicle's power supplies or one provided by the user (e.g., batteries), deriving power from it.
• the keyboard is in compact layout, which is aimed at being used with only one hand, ideally for shorter inputs.
• the keyboard is in full layout, extended over a wide horizontal portion of the smart surface. This layout is aimed at being used with both hands, ideally for longer inputs.
• different texture sensations are used to indicate to the passenger, e.g., when the finger is sliding on top of a virtual button (e.g., a different texture sensation is generated for each button, helping the user differentiate between different buttons); when the passenger enter/leaves the location of a virtual button (e.g., a sensation of a "bump" in generated when the skin reaches the edge of a button, and no texture sensation is generated between the gaps of each button); and the location of the index-finger locator keys, usually the F and J keys in QWERTY keyboards (when keyboard is in full mode), by way of noticeably different texture and bump sensations. In other alphabets, these locator keys can be adjusted accordingly.
