Definitions

  • Embodiments of the invention relate to touch surfaces, and, in particular, to electrovibration for touch surfaces.
  • Touch provides humans with a wide variety of sensations that allow us to feel the world. We can enjoy the feeling of textures, as well as objects and materials. Beyond experience, tactile sensations also guide us with everyday tasks and help us to explore object properties that we normally are not able to see.
  • the touch surface itself can be actuated with various electromechanical actuators, such as piezoelectric bending motors, voice coils, and solenoids.
  • the actuation can be designed to create surface motion either in the normal or lateral directions.
  • Such an approach has been used in the design of tactile feedback for touch interfaces on small handheld devices by mechanically vibrating the entire touch surface. With low frequency vibrations, a simple “click” sensation can be simulated.
  • a major challenge in using mechanical actuation with mobile touch surfaces is the difficulty of creating actuators that fit into mobile devices and produce sufficient force to displace the touch surface.
  • Creating tactile interfaces for large touch screens, such as interactive kiosks and desktop computers allows for larger actuators. Larger actuated surfaces, however, begin to behave as a flexible membrane instead of a rigid plate. Complex mechanical deformations occur when larger plates are actuated, making it difficult to predictably control tactile sensation or even provide enough power for actuation.
  • Embodiments of the invention provide an interface that allows users to feel a broad range of tactile sensations on touch surfaces.
  • a touch panel includes a transparent electrode covered by a thin insulation layer.
  • An electrical signal is coupled to the electrode or the back side of the device.

  • slides along the insulation layer of the touch panel a sensation of tactile texture is perceived.
  • Another embodiment provides a method for generating a signal.
  • the method includes detecting an impedance value of a user in contact with a device relative to a ground; generating a signal based on the impedance value; and causing the signal to be coupled to the user such that a tactile sensation is perceived in at least one digit that slides on an insulation surface of the device.

  • the user can be placed at a potential difference from the electrode.
  • our bodies provide a natural link to the ground, creating a direct ground connection can increase the intensity of the tactile sensation. Without such grounding, the voltage could be increased to provide the same intensity of sensation.

  • induced charge in the finger causes a force on the finger, and the amount of induced current flowing through the user's hand is negligible.
  • the current supplied to the touch surface 200 can be limited to 0.5 mA, which is typically considered safe for humans.
  • current limitation is defined by the power rating of an operational amplifier used in the driving circuit. In fact, users experience the same amount of current while using conventional capacitive touch panels. To further protect the user, some embodiments can implement a current limiting circuit.
  • Electrocutaneous displays stimulate tactile receptors in human fingers with electric charge passing through the skin. In contrast, there is no passing charge in electrovibration: the charge in the finger is induced by a charge moving on a conductive surface. Furthermore, unlike electrocutaneous tactile feedback, where current is directly stimulating the nerve endings, stimulation with electrovibration is mechanical, created by a periodic electrostatic force deforming the skin of the sliding finger.
  • a user is manipulating an intermediate object, such as a piece of aluminum foil, over an electrode pattern.
  • a periodic signal applied to this pattern creates weak electrostatic attraction between an object and an electrode, which is perceived as vibration when the object is moved by the user's finger.
  • the tactile sensation therefore, is created indirectly: the vibration induced by electrostatic force on an object is transferred to the touching human finger.

  • JNDs just-noticeable-differences
  • the detection and discrimination thresholds together form a set of fundamental measures that describe the dynamic range and processing capabilities of electrovibration sensations. These measures can be used to design interfaces and applications using embodiments of the invention.
  • the detection threshold levels for electrovibrations closely coincide with the force detection threshold levels for sinusoidal stimulus.
  • sensations created with embodiments of the invention are closely related to perception of forces lateral to the skin.
  • the relation between electrovibration voltages and perceived forces may not be linear.
  • the detection threshold levels provide guidelines for designing tactile interfaces using electrovibration. For example, the detection threshold levels inform the designer that at each frequency the applied voltage must be above the corresponding detection threshold level in order to provide a tactile sensation that a user can perceive. They also allow optimizing power requirements. For example, at 400 Hz the tactile signal could create an easily discernable tactile sensation at 18 dB re 1 V level or 16 Vpp. On the other hand, at 180 Hz the voltage threshold level is half of that, requiring significantly less power (12 dB re 1 V peak or 8 Vpp). Therefore, tactile feedback can be optimized to require less power, which can be especially important for mobile devices.
  • the frequency and amplitude discrimination thresholds describe the resolution of human perception: they determine the granularity of tactile sensations that can be used in designing interfaces. For example, if designers want to create two distinct tactile sensations, then they would make sure that the amplitude of voltages for each sensation are at least a certain voltage different apart from one another for the user to be able to differentiate them. Similar considerations also apply for frequency of stimuli.

  • Embodiments of the invention offer several significant advantages over conventional mechanical vibrotactile actuation on touch screens.
  • the absence of mechanical motion in electrovibration actuation techniques is the most immediate difference between embodiments of the invention and conventional mechanical actuation. This feature has several notable implications.
  • any plane of material will flex when actuated. This problem is exacerbated when the plate is large and actuation forces are applied on its periphery, which is common when designing tactile feedback for touch surfaces. Consequently, not only are vibrotactile solutions not feasible for large interactive surfaces, but even for small screen sizes, different parts of the screens would have different magnitudes of physical displacement and, therefore, different tactile sensations. Electrovibration, on the other hand, does not suffer from this effect as electrical potential is evenly and instantaneously distributed over the entire plate.
  • the tactile feedback in embodiments of the invention is uniform across surfaces of any size.
  • vibrotactile actuation delivers tactile feedback by displacing the entire surface.
  • all fingers resting on the surface will be stimulated and any physical object located on the surface is likely to chatter and move around, which is less favorable.
