Initial Sketch
The design of the vest had to be capable of adapting to the size of eight-year-olds to grown adults. The initial sketches featured an electronics case resting slightly below the collarbone, as this would have the least amount of variability in shape from person to person. The vest straps are adjustable, and the waist straps include a long elastic band with velcro.

Casing
Casing
This housing system is designed to seamlessly integrate the electronic components into the vest design, while maintaining the vests' adaptability to all ages and sizes. The vest straps go through the rectangular fittings on three sides of the casing, and the large hole fits a haptic motor to provide user feedback when shot.

Final Vest
The final product integrates the electronics with the vest, and has a light wire for added aesthetic purposes. The double strap and velcro around the waist ensure that the vest stays in place throughout the game, as laser tag can get very physically active. The top straps of the vest are adjusted so that the vest is comfortable for the wearer. Lastly, LEDs (not shown in the pictures) light up in the casing for added aesthetics, and turn off when the player has been shot. This gives a visual indicator to other players of their status in the game.

Initial Challenges
Laser tag traditionally uses guns to fire at opponents. However, Duke has a no-weapons policy, so we had to brainstorm a new means of doing this. We settled on a glove design, as it gives a new and unique experience to the game.
The outside of the glove is shown on the left, and the inside is on the right.
Final Sketch and Design
Final Sketch and Design
The design is based on wrist braces, as these are designed to fit a wide range of arm sizes and lengths. The elastic bands (drawn in green) are threaded through rivets, and can be pulled taught to tighten the glove around the user's arm. Velcro (the shaded region) covers almost the entire glove, and ensures maximum adaptability. The thumb strap adds extra stability to the glove, ensuring it doesn't slip along the user's arm during gameplay. Lastly, a velcro pocket (the two rectangles in the middle of the glove) houses a magnetic metal piece that rests on the top of the user's arm.

The electronics casing for the glove was modeled after the circuitry was completed. It houses a red 650 nm laser (a visual aid to help the player aim), an IR transmitter, a haptic motor, and a battery. There is also a button connected to a wire that the user can hold in their hand, and press to fire. It has a magnet attached to its underside, which helps it attach to the top of the user's arm where the metal piece is located. The attachment of this casing to the glove is also reinforced by a long velcro strip that hugs the casing and fastens around the entirety of the glove. Using both magnets and velcro ensures that the casing doesn't fall off during the game.
This casing was designed to be attachable and detachable for an increased variability in the game experience. It can be attached on the underside of the player's arm instead of the top, which allows for a Spider-Man shooting experience.

Homebase
Homebase
The homebase casing was designed to protect the raspberry pi, touch screen, and battery pack that serve as the brain of our game. The design allows for the screen, pi, and battery to be assembled in one place, with easy access to recharge the battery. Unfortunately, since the raspberry pi doesn't have an on/off switch, we had to design the casing to be easily removable so we could remove/add power to the pi.
