An embodiment of the present disclosure provides a touch apparatus including: a touch sensor; and a touch controller operating in a full driving mode for applying a first driving signal for generating a resonance signal of a stylus pen to the touch sensor and a skip driving mode in which a second driving signal having a period having an off-duty different from that of the first driving signal is applied to the touch sensor, and obtaining touch coordinate information from a detection signal received from the touch sensor.

The disclosed technology provides for a device and method related to powering an electronic stylus with a removable, integrated battery that acts as a structural segment and external casing along the long axis of the stylus body. The integrated battery incorporates interlocking features, which removes the need for an external tube around a battery cell. As a result, the electronic stylus has one structural component performing multiple functions (e.g., providing power, functioning as the stylus casing), which achieves a more lightweight and compact electronic stylus. The placement of the battery along the long axis can vary to provide comfortable weight distribution for writing, which can involve an interlocking interface at one end of the battery or at both ends of the battery (e.g., to interlock with one or both ends of the electronic stylus).

A touch sensor panel is disclosed. In some examples, the touch sensor panel comprises a plurality of touch node electrodes. In some examples, the touch sensor panel comprises a touch controller configured to drive and sense the plurality of touch node electrodes in a fully bootstrapped configuration to obtain a fully bootstrapped touch image, drive and sense the plurality of touch node electrodes in a second configuration, different from the fully bootstrapped configuration, to obtain a second touch image, the second touch image including an effect of water on the touch sensor panel, and determine a final touch image based on the fully bootstrapped touch image and the second touch image, the final touch image not including the effect of the water on the touch sensor panel. In some examples, the second configuration comprises a mutual capacitance configuration. In some examples, the second configuration comprises a partially bootstrapped configuration.

A writing instrument configured to provide tactile feedback to a user, comprising an elongate body portion enabling a user to grip the writing instrument, wherein the body portion comprises a proximal end and a distal end, the proximal end comprising a source of infra-red radiation to illuminate, in use, an active region of a writing surface; and a controller configured to generate a control signal for controlling the source of infra-red radiation. The source of infra-red radiation, driven by the control signal, emits infra-red radiation having a spectral maximum in wavelength range capable of activating thermal bimorph polymer material, and wherein, in use, the proximal end of the writing instrument, when in contact with the active region of the writing surface transfers a tactile impulse generated by the active region of the writing surface to the user via the elongate body portion.

A computer implemented method for computing a plurality of virtual texture waveform definitions, comprising: obtaining first texture data at least partially characterising a texture of an existing writing surface, obtaining second texture data at least partially characterising an intended texture experienced by a user when the haptic writing instrument when writing on the existing writing surface, generating virtual texture data by modifying the first texture data based on at least the second texture data, segmenting the virtual texture data into at least first and second regions representing, respectively, at least a first texture type and a second texture type, generating at least first and second virtual texture waveform definitions corresponding, respectively, to the first and second texture types, and outputting at least the first and second virtual texture waveform definitions.

An electronic apparatus and a method of controlling the same, the electronic apparatus including: a display; and a processor configured to: receive a writing input for user authentication, identify writing content of the writing input and pen attribute of the writing input, perform the user authentication based on whether the identified writing content of the writing input and pen attribute of the writing input match writing content and pen attribute obtained in association with authentication data of a user registered prior to the writing input being received, and control the display to display an image based on the writing input according to which the user authentication has been performed.

A home device controller can include one or more touch grooves, a touch slider operatively coupled to each of the one or more touch grooves, and one or more processors. The processor(s) can receive signals from each touch sensor, each signal corresponding to a touch gesture performed by a user interacting with the one or more touch grooves. The processor(s) can generate control commands executable by a home device based at least in part on the signals, and transmit the control commands to the home device for execution.

Provided is a position detection circuit for detecting a position of an electronic pen and a position of a passive pointer on a touch surface disposed on a capacitive touch sensor constituted by a plurality of sensor electrodes arranged two-dimensionally, the electronic pen being configured to be capable of transmitting a pen signal, the passive pointer not transmitting any signal, the position detection circuit configured to detect a touch position indicative of the position of the passive pointer, and output the touch position if a size of a region forming the touch position is within a predetermined range, in which, if the electronic pen was in contact with the touch surface and becomes detached therefrom, the output of the touch position is temporarily inhibited.

A smart pen includes a body, a pen tip portion at an end of the body, and including a pen tip extending in a first direction, a pen tip support configured to support the pen tip, and a reflector on one surface of the pen tip support, and having a curvature, and a light emitter supported by the body, configured to emit light, and inclined at an angle with respect to the first direction.

A user terminal apparatus is provided. The user terminal apparatus for performing a remote control function for an electronic apparatus includes a communication unit configured to communicate with an electronic apparatus for providing a text input user interface (UI), an input unit configured to receive a user command for input of a specific text on the text input UI, a fingerprint scanner provided in the input unit and configured to recognize a user fingerprint, and a controller configured to recognize a user fingerprint according to the user command and to transmit information corresponding to the recognized user fingerprint to the electronic apparatus in response to the electronic apparatus entering a preset text input mode.
