Ranging Glove

Overview The Ranging Glove is a device able to provide spatial commands over Bluetooth. The glove over the dominant hand (right in this case) contains a laser rangefinder and laser pointer that are pointed at a location on the ground/floor or nearby wall. Other sensors, such as accelerometers, a compass, and gyroscopes, provide the angle relative to the ground. The output coordinate frame can be considered a “top down” plane in parallel with the ground, with the device’s current position being the origin point. Compass data may also be used to calculate this, but it is not preferred. Sensor data and trigonometry are used to provide the X and Y values of the endpoint of the laser beam’s end point. The required distance is within 3 meters, although up to 5 m is preferred. Default Coordinate Frame When a button (#1 in the diagram, on top of the dominant hand pointer finger) is pressed, the coordinates are sent out over Bluetooth. A Raspberry Pi (or Arduino or similar device) and power source (attached via battery) are used for the calculation to the x and y of the output coordinate frame. The output values, plus a timestamp, must be calculated and send out on Bluetooth with each push of Button #1. It should delete all but the last 5 data outputs (button 1 state, button 2 state, button 3 state, additional button states if present). In addition, the press of other buttons (#2 and #3 on the dominant hand, the rest on the other glove), should be output as a binary vector (0 for not pressed, 1 for pressed). Adjusted Coordinate Frame Button #3 has a special function. When the glove is pointed at an object and Button #3 is pressed, it stores the X and Y distance to that object. The next time Button #1 is used, it does so with respect to the absolute distances relative to the point used with Button #3. For example, say Button #3 is pointed at an object at X= -2 m, and Y= -1 m. Button #1 is pressed at a space at X= 3 m, and Y= 2 m. The resultant coordinates broadcast would be X= 5, m and Y= 3 m. This is only performed in case Button #3 is pressed before Button #1. The final product specifications are: -Preferably assembled using open source and generic components. -Have at least 3 m of range. -Calculate the X and Y of both the self-centered coordinate frame and adjusted frame. -Each press of Button #1 should save up to the prior 5 data outputs (each containing X, Y, timestamp, angle relative to self, compass bearing, button 1 state, button 2 state, button 3 state, additional button states if present). -Trigger output of information vector using Bluetooth, with each button press. Bonus: -Design a glove for the other hand, containing buttons #4, #5, and #6. It may be connected to the first using long wires, its own device, or some other means. Desired Outputs: -Circuit and Wiring Schematic/Diagram -Code for all devices -Physical prototype
