Apparel is disclosed that can be worn to assist an interactive game in tracking the movement of the wearer. More particularly, the apparel may include one or more tracking marks formed of designs, patterns, or reflective materials that can be easily tracked by an interactive game employing one or more cameras or other detectors for detecting a change in position of an object. The apparel may take the form of, for example, hats, shirts, jackets, pants, gloves, and shoes. By providing tracking marks on apparel, rather than using a special-purpose device that must be separately worn, a player may enjoy a more natural feel when playing the interactive game. Further, the player need not don any special equipment to play the game. Instead, a user can wear the apparel for everyday purposes, and then simply begin playing the game wearing the apparel without having to put on any additional equipment. The apparel may use reflective materials, and the interactive game can employ a camera and a light source configuration where the camera is located within the observation angle of a player employing retroreflective materials reflecting light from the light source.

A securing device for preventing removal of a shoe comprising a web selectively attachable to an outer surface of a shoe and configured to at least partially cover the shoe. The web includes a bottom portion having a center section securable to a front region of the shoe and a leg support section securable to a user's leg. The web further includes a top portion removably couplable to the bottom portion. The top portion includes a coupled position at least partially covering a lace of the shoe and an uncoupled position leaving the lace of the shoe exposed to an ambient environment.

A subtractive color change system for displaying a selected color to a viewer and a method of changing color. The system includes a layered assembly having transparent panels of primary and key colors, with a fixed-color background behind the layered assembly. The subtractive color change system may have a control unit to individually control the intensities and values of the primary color panels to render a color and to control the intensities and values of the panels in the layered assembly to reduce differences between the color rendered and the selected color and to display the selected color to a viewer.

A system assesses activity and displays a unitless activity value. A detector senses activity of a user. A processor reads sensed activity data from the detector. A display displays the unitless activity value. An enclosure houses the detector and the processor. The processor periodically reads the sensed activity data from the detector and processes the data to generate an activity number, the number being used to generate the unitless activity value based upon a maximum number and a display range.

Some embodiments provide reflective safety apparel that combines passive illuminating elements with active illuminating elements for improved nighttime visibility. The active illuminating elements include a laser module coupled to flexible laser tubing. The laser module directs laser light into the flexible laser tubing. The laser tubing retains and transfers the laser light throughout its length even when bent. This flexibility allows the active illuminating elements to outline and conform to the shape of the passive illuminating elements. The laser tubing from different garments, such as a jacket and pants, can be coupled together. A single laser module can illuminate both garments as the laser light traverses the laser tubing of one garment to the other.

Provided herein are methods for the modulation of appearance or material properties within items of apparel or equipment. Also provided herein are design articles having alterable designs. Generally, such design articles comprise (1) a microfluidic circuit, and (2) an inlet and an outlet, the alterable design capable of being modulated through use of a docking system to deliver fluid to the microfluidic circuit.

Articles of footwear and footwear systems include modules, e.g., for sensing physical and/or physiological characteristics associated with use of the footwear or for performing other functions. Such systems and methods may use physical or other interaction(s) between the module and the article of footwear for activating and/or deactivating the module and/or sensing devices included with the module, for confirming whether the module and footwear are authorized for use with one another, and/or for automatic data algorithm selection methods. Additionally, such systems and methods also may use the activation and/or authentication systems for the module for data input to the module. Some examples of such systems and methods may utilize magnets and magnetic sensing systems and/or light (or other radiation) sources and sensing systems for activation, authentication, data input, and/or algorithm selection.
