In some embodiments, a method receives an input for an application in which content is displayed in a user interface and receives an input classification that classifies the input in one of a plurality of input classifications. A user interface format is selected from a plurality of user interface formats based on the input classification and content is selected for the user interface format. The method causes output of the content in the user interface format on the user interface.

A position detection system detects a position of an active pen. The position detection system includes: a display device that displays image data by driving each of a plurality of pixel electrodes; and a touch panel including a sensor electrode and a touch sensor. The active pen communicates with the touch sensor using a frequency included in a predetermined frequency band by a charge induced in the sensor electrode. The display device suppresses at least one frequency component included in the predetermined frequency band in capacitive noise that occurs in the sensor electrode due a voltage vibration in an interconnect in the display device caused by driving of the plurality of pixel electrodes. The active pen and the touch sensor communicate by detecting or sending out a signal with a predetermined frequency included in the predetermined frequency band.

The visual teaching solution provides a course-oriented and student-oriented visual teaching environment by combining the courses, teaching devices and students.

A timepiece mechanism including a deformable rhombus including four coplanar segments pivotally connected in pairs by their vertices, including an input segment adjacent to an output segment, both pivoted about a pivot axis perpendicular to the plane of the rhombus and passing through a first vertex common to the input and output segments and locked in translation in the plane of the rhombus, a lever mounted to pivot about the pivot axis, the lever being kinematically connected in rotation, about the pivot axis, to a second vertex of the rhombus, opposite to the first vertex, a first locking member movable between a first locking position, in which the lever is locked in rotation, and a first unlocking position in which the first locking member does not hinder rotation of the lever, a second locking member movable between a second locking position, in which the second vertex is locked in translation in a radial direction, and a second unlocking position in which the second locking member does not hinder radial movement of the second vertex.

The present invention proposes a timepiece mechanism comprising: a lever, rotatable about a lever axis, the angular position of the lever representing a first value, wherein a zero value of the first value corresponds to a reference direction, a sliding block mounted to move in translation on the lever in a direction substantially perpendicular to the axis of the lever and comprising a guide-mark element whose trajectory in translation relative to the lever is secant to the lever axis, the radial position of the guide-mark element with respect to the lever axis representing a second value, an output device formed of a deformable parallelogram in a plane perpendicular to the lever axis, the parallelogram including a first side, which is stationary with reference to the lever axis and perpendicular to the reference direction, a second side, which is opposite to the first side and linked in translation to the guide-mark element in the direction perpendicular to the reference direction,
the angular position of the third and fourth sides of the parallelogram, which are adjacent to the first side, being substantially proportional to the product of the first and second values.
