Objectives Game Outdoor Collaborative Physically Active 10-15 year old kids
Description Equipment 1 Ball 2 Goals 1 Glove per player Rules 2 teams Players earn points by capturing opposing players flags Flags a recapturing by gaining control of ball Teams earn points by throwing ball into goal Goal points are dynamic, value is the number of flags the team has at time of goal
How the Game Works - RFID RFID system consists of three parts: Scanning antenna Transceiver to decode data Tag with info. Flagging Dynamic Player A touches Player B, sends deflag signal Goal picks up this state change, updates display Ball sends out reflag signal, acquisition returns flag
How the Game Works - RFID Teams each have a main signal Individual team members have another unique ID Glove System: Embedded Passive tag Very short signal distance Long life span Goal System: Active RFID Large signal range, tracks RFID objects in playfield Sends out powering signal to gloves Ball: Emits reflag signal constantly Scores goals by hitting pressure plate in goal, no RFID required
Feasibility Gloves: Passive RFID Very cheap, approx. $0.50 Parts woven into gloves, lesser chance to break Goals: Active RFID More expensive, approx. $5.00 or more Larger device: goal net, hard plastic construction, pressure plate, interface screen Currently existing technology NERF Cosmic Catch Shorter development time Plan around previous products shortcomings
Glove Display screen is off. Display screen is on.
Glove Player 3 - receives an individual point for capturing player 2 flag. Player 2 - flag light turns red to indicate no flag.
Prototyping Session 1 Tested game setup (4 players independently) Tested game play with 4 players Session 2 Tested game setup without instructions Tested game setup with instructions Tested game setup with 2 team captains Tested taking and regaining flags
Lessons Learned The position of the start button on the goal display was in a bad location. Users were pressing start before setting the time because the button was near the locus of attention of the last interaction.
Lessons Learned The goal display should more clearly show that the inner portion is for display only, not a touch screen, and that the input occurs sole through the buttons on the frame and the buttons on the gloves. Add a help screen that would show how to set-up the game in several easy to follow steps.
Next Steps Test game with kids Test devices to measure physiology during game play (heart rate, etc) Alter point calculations based on these physiology measures (promote participation)
