A wearable electronic device includes a primary bead, two spacer beads and a bead string. The two spacer beads each defines a first side and a second side opposite to each other. The first sides of the two spacer beads are respectively disposed on two opposite sides of the primary bead. Two ends of the bead string are respectively connected to the second sides of the two spacer beads.

An embodiment of the present invention provides a counting information updating method for a portable electronic device having a plurality of spheres connected with each other. The method includes: generating an angular velocity signal by a first sensor of the portable electronic device and generating an acceleration signal by a second sensor of the portable electronic device in response to a sphere moving operation; and estimating counting information corresponding to the sphere moving operation by using the angular velocity signal with an assistance of the acceleration signal.

System, methods, and other embodiments described herein relate to performing an interactive activity using a band. In one embodiment, a method includes touching a subset of inputs, associated with a touch sensor of a first band, relating to an interactive activity with a second band. The method may also include communicating, by the first band, first data to a first mobile device, the first data including information that identifies completion of the interactive activity and indicates a time that the subset are selectively touched. The method may also include the first band triggering the first mobile device to communicate second data to a second mobile device to replicate the interactive activity.

An electronic bead string includes a main bead, a plurality of secondary beads, a displacement sensor, a memory, and a processor. The main bead and the secondary beads are strung together to form a bead string. The displacement sensor is fixed in the main bead to output two-dimensional displacement signals, the memory stores the two-dimensional displacement signals, and the processor determines whether a rotation cycle of the electronic bead string is an approved rotation cycle according to the two-dimensional displacement signals.
