A wheel device is applied to a mouse and includes a supporter, a wheel module, a lighting unit and a sheltering component. The wheel module includes a wheel axle, an encoder and a wheel component. The wheel axle includes an axle body, a wheel surface and a wheel frame. The axle body is rotatably disposed on the supporter and on center of the wheel frame. The wheel surface is located on an outer surface of the wheel frame. The encoder is connected to the axle body to detect rotation parameters of the wheel axle. The wheel component covers the wheel surface. The lighting unit is disposed on the supporter and inside the wheel frame, and emits an illumination beam to the wheel module. The sheltering component is disposed on the supporter and covers the lighting unit to prevent the illumination beam from leakage through two sides of the wheel component.

A golf training device and method indicates the proper position and/or motion of the golfer's trail wrist during the club downswing. The device may detect that desired DWLA is attained and provide real-time alerts of same. The device may provide positive feedback in the form of an auditory, tactile, visual and/or other signal.

Implementations include methods of controlling a haptic response comprising receiving a force signal from a force sensor; determining a force magnitude associated with the force signal; comparing the force magnitude with an initial threshold force amount to determine whether the force magnitude exceeds the initial threshold force amount; measuring an elapsed time that the force magnitude exceeds the initial threshold force amount; comparing the elapsed time to a minimum elapsed time; if the elapsed time being greater than the minimum elapsed time, generating a haptic feedback control signal, the haptic feedback control signal causing a haptic actuator to propagate a plurality of pressure waves at a propagation frequency, the propagation frequency being proportional to the force magnitude; and generating a scroll control signal that causes a menu system to scroll through a plurality of menu options provided by the menu system at a scroll frequency associated with the propagation frequency.

An apparatus to target recipients of media content items comprises a camera, a communication interface, and a selector input device. The selector input device is communicatively coupled to the camera and the communication interface and has settings associated with groups of recipients. The groups of recipients include a first group and a second group. In response to receiving a selection of a first setting from the selector input device, the camera captures a first media content item and the communication interface transmits the first media content item to the first group. The selector input device can be a rotary wheel. To select the first setting from the plurality of settings, the user can rotate the rotary wheel to the first setting and press the rotary wheel. Other embodiments are described herein.

A roller module includes a supporting seat, a scroll wheel, a linkage rod, a torsion spring, a first magnet, a second magnet and a coil. The scroll wheel is installed on the supporting seat. The linkage rod includes a fulcrum segment, a resisting segment and an effort segment. The torsion spring is connected with the resisting segment. The first magnet is arranged between the second magnet and the effort segment. The coil is arranged around the second magnet. When the roller module is in a tactile mode, the first magnet and the second magnet are close to each other, and the torsion spring exerts a pulling force on the resisting segment. Consequently, the resisting segment is contacted with a toothed region of the scroll wheel. When the roller module is in a non-tactile mode, the resisting segment is moved away from the toothed region.

A rotation operation detection mechanism that includes a housing, an operation surface disposed on a first main surface of the housing, operation units formed integrally with the housing and protruding on the operation surface side, and a sensor that detects a stress generated in the housing when the operation units are rotated.

User interface navigation on a personal electronics device based on movements of a crown is disclosed. The device can select an appropriate level of information arranged along a z-axis for display based on crown movement. The navigation can be based on an angular velocity of the crown.
