Abstract: . . .  Receiver      For our design, we assume the user stays the range of area near to the stick.  Test range between wrist circuitry and the stick : ~40 ft            The javelin still could capture the digital  signal.   36   Recommendations   Better biosensors that reduce noise when hands are moving. Better circuit design to reduce power consumption. Lighter material for the wrist circuitry and the main unit on the stick.  . . .
. . .  Stamp to test the wireless communication between wrist and the stick. -Suitable bluetooth module was selected carefully by reading data sheets to check certain commands to make sure that it is connectable to a cell phone.   33   Successes & Challenges   The notion of AT commands was obtained by surfing online technical forums. AT commands were given by somebody met at a technical forum.   34   Test   Operation Temperature We chose the reasonable range of outer weather. Test Range: -25C to 50C inside freezer and by hair dryer Result: We could observe that the whole system behaved properly.   35   Test (continued)   Transmitter / Receiver      For our design, we assume the user stays the range of area near to the stick.  Test range between wrist circuitry and the stick : ~40 ft            The javelin still could capture the digital  signal.   36  . . .
