The invention provides a method for automatically identifying emotional states of a person in real-time based on physiological responses by exposing a person to a stimulus, measuring the person's physiological response to the stimulus, and comparing the measured physiological response to a known baseline physiological. The deviation of the measured physiological response from the baseline physiological response is determinative of the emotional state.

In one embodiment of the present invention, a haptic engine dynamically configures a haptic controller to provide information regarding the state of an interactive system via sensations of texture. In operation, as the state of the interactive system changes, the haptic engine dynamically updates a haptic state that includes texture characteristics, such as texture patterns, that are designed to reflect the state of the interactive system in an intuitive fashion. The haptic engine then generates signals that configure touch surfaces included in the haptic controller to convey these texture characteristics. Advantageously, providing information regarding the correct state and/or operation of the interactive system based on sensations of texture reduces distractions attributable to many conventional audio and/or visual interactive systems. Notably, in-vehicle infotainment systems that provide dynamically updated texture data increase driving safety compared to conventional in-vehicle infotainment systems that often induce drivers to take their eyes off the road.

There is provided an information processing device to reduce the difference in way of feeling a tactile sense in accordance with a state or situation, the information processing device including: an acquisition unit configured to acquire context information concerning a state or a situation user of an external environment or context information concerning a user; and a modulation unit configured to modulate a control signal for controlling a haptics unit for presenting haptics to a predetermined part of the user on the basis of the context information having been acquired.

A page element display method and an electronic device (100 or 1500) are provided. The method includes: The electronic device (100 or 1500) displays a first interface, where the first interface includes a first page element (1401); the electronic device (100 or 1500) detects a first operation performed by a user on the first page element (1402); the electronic device (100 or 1500) adjusts a size of the first page element in response to the first operation (1403); and the electronic device (100 or 1500) automatically displays a second interface after adjusting the size of the first page element. The method helps to enhance an effect of feedback from the electronic device (100 or 1500) to the user when the user performs the operation.

An embodiment for managing finger movement with haptic feedback is provided. The embodiment may include receiving historical data regarding a navigation pattern of a user on a device. The embodiment may also include identifying a context of a current interaction of the user with content displayed on a touchscreen of the device. The embodiment may further include predicting an action required of the user. The embodiment may also include identifying a target location on the touchscreen of the device where the action is required. The embodiment may further include in response to determining a finger of the user is not at the target location, generating one or more haptic feedback vectors that guide the finger of the user to the target location. The embodiment may also include prompting the user to touch the touchscreen of the device at the target location.

The present disclosure generally relates to techniques and interfaces for managing media playback devices. In some embodiments, the techniques include varying a feedback based on movement of a computer system toward or away from an external device. In some embodiments, the techniques include displaying an interface that includes controls for controlling media playback on an external device when the computer system and the external device are playing media. In some embodiments, the techniques include performing operations at a computer system in response to an input having a size that is less than or greater than a size threshold. In some embodiments, the techniques include performing different operations at a computer system when status lights have states that indicate different states of the computer system.

In some embodiments, a device displays functionality information in response to receiving an indication of a first input for which a contact meets functionality display criteria. In some embodiments, a device generates a user interface that includes a navigation bar including images from different positions in a respective content item, and a representation of an adjacent content item. In some embodiments, a device moves a selection-indicator in a user interface by a predefined amount in response to receiving an indication of a first input that meets unitary movement criteria. In some embodiments, a device interprets movement of a contact of an input based at least in part on a grip of a user. In some embodiments, a device displays a plurality of character selection options when a text entry field is not tolerant of character ambiguity and a first input corresponds to a plurality of candidate characters.

A cooking appliance includes a plurality of electrically controlled heating elements operable to elevate a temperature of food items. A user interface includes a touch-sensitive circuit that is operatively-connected to an external surface of the cooking appliance for altering operational settings of the electrically controlled heating elements. An electrovibration feedback circuit is coupled to the external surface that generates a vibratory feedback that is sensible by the user's finger at the external surface in response to adjustments of the operational settings. The electrovibration feedback circuit creates an electrostatic force on the user's finger that simulates friction between the user's finger and the external surface.

An electronic device includes a tactile sensation providing unit 30 configured to provide a tactile sensation to a contact object being in contact with a panel 10 and a controller 50 configured to control the tactile sensation providing unit 30 based on an amount of change of data based on press to the panel 10.

The application includes an apparatus connectable with a portable electronic and/or consumer electronics device that provides haptic information and/or feedback to a user of the portable electronic device. The apparatus may include one or more acousto-haptic transducers that provide at least one of audio and haptic output to a user of the portable electronic device. Systems and methods also provide a vibrating membrane or waveguide that transfers haptic or vibrational feedback to a user that touches the membrane using, for example, their finger. The membrane may be transparent, allowing the membrane to be overlaid over a touch screen, keypad, and/or keyboard to provide haptic feedback to a user as the user types on the touch screen. In this way, a user can continue to view the touch screen or display of a media device while experiencing haptic sensations from the vibrating membrane.
