The present invention relates to a haptic information provision device. The haptic information provision device (100) according to the present invention comprises: a receiver (120) for receiving external notification information; a controller (130) for converting the notification information to a haptic signal; and an operation unit (110) for transferring haptic information to a user according to the haptic signal, wherein the operation unit (110) includes a plurality of operation units (110a-110j), the respective operation units (110a-110j) operating in response to different notification information and thus transferring different haptic information to the user.

A method to track an individual wearing a battery-operated wearable and lockable tracking device. An identification number is provided on the tracking device or separately from the tracking device and remotely stored. Device location information about the tracking device is received from the location tracker. Based on the location information received, a determination is made whether the individual is potentially subject to a condition. In such case, the device location is tracked, and the individual is wirelessly alerted and tracked. Upon tracking, the individual is identified by scanning the QR code and revealing the personal information about the individual.

A band may include a first strap and a second strap. The first strap may include a first strap body, a first connection portion and a first mating portion. The first strap body may define a connection hole between the first connection portion and the first mating portion. The second strap may include a second strap body, a second connection portion, a second mating portion and a buckle. The second mating portion may be arranged between the second connection portion and the buckle. The buckle is configured to be inserted into the connection hole to connect the first strap body and the second strap body. The second mating portion may be configured to be attracted to and coupled with the first mating portion.

An electronic device may include a main body including a front plate, a rear plate disposed to be spaced apart from the front plate, a lateral member surrounding a space between the front plate and the rear plate, and a display viewed through at least a portion of the front plate. The electronic device may further include a housing having a space therein and combined with a strap at one side thereof in a first axial direction, a first fastening part protruding from another side of the housing toward the main body and detachably connected to the main body, a second fastening part formed in the main body and engaged with the first fastening part, and a button disposed in the housing, exposed at least in part to an outside of the housing, and moving the first fastening part to be separated from the second fastening part.

Systems and methods are presented for establishing a communication link between two or more electronic devices. A portable eyewear electronic device is configured to communicate with a handheld electronic device, such as a ring, that in turn is retained by an accessory electronic device to establish a wired communication link. The accessory electronic device may be retained or housed by a second accessory electronic device, such as a remote control or wearable device.
