We propose using a pair of gloves to control light design on a stage, which can be used for uses practical to musical performances and theatre shows. The purpose of this project is to accomplish simpler goals in relation to these areas rather than running a full production. This could be controlling a spot light on an actor or, in a musical production it could allow a unique control over the lights that most, if any, groups out there do not have. This means the focus would be more for the flash and performance, or simplicity in the case of theatre, than for large scale utility.

There will be a limitation to keep the complexity within the scope of this course. The limitation is that the light designer cannot walk freely in relation to the lights. The designer must remain behind or in front of the lights. Think of this as the light designer must be on stage directing the lights or off stage. With this limitation, we will not have to solve the problem of keep track of where the designer is. Now with the designer and lights both in fixed locations, we will still have a control unit with all the lights in the system connected to the control unit. All lights in the system will be servo motor based. The designer will still wear a single glove that communicates to the control unit via Bluetooth.

The glove will have its own microcontroller, and bluetooth transmitter, one flex resistor in the pointer finger, and four buttons and four LEDs, and will be powered via 9Volt battery. The designer will select which lights to control via the buttons and the glove will indicate which lights are currently selected via the LEDs. Further, the designer will control which direction the currently selected lights point at by pointing his finger and gesturing the direction he/she wants the lights to point towards. When the finger is not fully extended (flex resistor not active), the lights will not move.

Assistive Chessboard

Featured Project

Problem: It can be difficult for a new player to learn chess, especially if they have no one to play with. They would have to resort to online guides which can be distracting when playing with a real board. If they have no one to play with, they would again have to resort to online games which just don't have the same feel as real boards.

Proposal: We plan to create an assistive chess board. The board will have the following features:

-The board will be able to suggest a move by lighting up the square of the move-to space and square under the piece to move.

-The board will light up valid moves when a piece is picked up and flash the placed square if it is invalid.

-We will include a chess clock for timed play with stop buttons for players to signal the end of their turn.

-The player(s) will be able to select different standard time set-ups and preferences for the help displayed by the board.

Implementation Details: The board lights will be an RGB LED under each square of the board. Each chess piece will have a magnetic base which can be detected by a magnetic field sensor under each square. Each piece will have a different strength magnet inside it to ID which piece is what (ie. 6 different magnet sizes for the 6 different types of pieces). Black and white pieces will be distinguished by the polarity of the magnets. The strength and polarity will be read by the same magnetic field sensor under each square. The lights will have different colors for the different piece that it is representing as well as for different signals (ie. An invalid move will flash red).

The chess clock will consist of a 7-segment display in the form of (h:mm:ss) and there will be 2 stop buttons, one for each side, to signal when a player’s turn is over. A third button will be featured near the clock to act as a reset button. The combination of the two stop switches and reset button will be used to select the time mode for the clock. Each side of the board will also have a two toggle-able buttons or switches to control whether move help or suggested moves should be enabled on that side of the board. The state of the decision will be shown by a lit or unlit LED light near the relevant switch.
