2 Our Project 1. Will the review of performance measures from prior trials improve a participant s time in completing the game? 2. Will playing a game tutorial (in addition to reviewing performance measures from prior trials) better a participant s time in completing the game? Tools: Labyrinth2 game app SensorKinetics app Two Smart phones - one to play the game and one to record the movement of the phone playing the game with another phone which records the results on the SensorKinetics app

3 The Game: Labyrinth Labyrinth is a game that was first introduced in 1946, and involved manipulating a steel ball through a maze by tilting the board on either a horizontal or vertical axis, using gravity to pull the board in a particular direction. The board could be manipulated on a third axis when the combination of the horizontal and vertical axes were used at the same time.

4 The Game: Online version of Labyrinth Now online, the game has multiple levels and a variety of challenges. Success can now be measured by the time that it takes one to complete the maze. Manipulation: playing the game on a phone allows the user to easily manipulate the board in three angles identified as: Pitch - the left/right phone tilt Roll - the top/bottom phone tilt Yaw - the diagonal phone tilt

5 Experiment Design Player 1 Baseline 1: Experienced player will play a designated maze in the game (thief round) multiple times to attain a time that is defined as the Designer Time (expert time). Once attained, this will be recorded as Baseline 1. Player 2 Baseline 2: Blind: A player with no prior experience playing the game will play the maze once. Results will be recorded as Baseline 2. Player 3 Trial 1: Intervention: Chart player (player with no prior experience playing labyrinth) will use knowledge from the analysis of Baseline 1 and Baseline 2 to play the thief round once. Results will be recorded as Trial 1. Player 4 Trial 3: Second Intervention: Tutorial player (player with no prior experience playing labyrinth) will use the analysis from Baseline 1 and Baseline 2, and play three rounds of the labyrinth tutorial before playing the thief round once. Results will be recorded as Trial 2.

6 Measures We had participants play the game with two cell phones bounded together. After completing the round, the data will be collected in Sensor Kinetic App on the phone. (1) Sensor Kinetic App on an iphone. (2) Labyrinth Game App on an android cell phone. Gyroscope Sensor: measures rotational velocity along the Roll, Pitch and Yaw axes.

7 Baseline 1 Baseline 1 was completed in approximately 20 seconds. It shows large movement when the game first starts, but after three seconds, the following range is recorded: Pitch: between and Roll: between and Yaw: between and -1.47

8 Baseline 2 Baseline 2 was completed in approximately 250 seconds. The gyroscope results show large movement in the first 50 seconds, including: Pitch: exceeding and reaching Roll: between and Yaw: between and -.65 After the first 50 seconds, the range recorded is: Pitch: between +1.7 and -1.4 Roll: between +1.7 and -1.6 Yaw: between +.3 and -.5

9 Comparing Baselines The participant in Trial 1 and Trial 2 reviewed the results of the first two baselines, prior to playing the game for the first time.

10 Results: Trial 1 Trial 1 was completed in approximately 110 seconds. The gyroscope results show large movement at 25, 50, and 70 seconds, including: Pitch: between and Roll: exceeding and reaching 1.11 Yaw: between +.44 and-.30 After the first 80 seconds, the range recorded is: Pitch: between +.3 and -.5 Roll: between +.5 and -.1 Yaw: between +.1 and -.1

11 Results: Trial 2 Trial 2 was completed in approximately 25 seconds. It shows some large movements at the beginning, but after ten seconds, the following range is recorded: Pitch: between +.83 and -.73 Roll: between and Yaw: between and -.48

12 Comparative Results baseline 1 baseline 2 trial 1 trial 2 pitch range roll range yaw range time r average baseline 1 baseline 2 trial 1 trial 2 pitch roll yaw time

13 Statistical Results Comparison All pairwise comparisons between the baselines and the trials were determined to be significant.

14 Conclusions The review of performance measures from prior trials improves a participant s time in completing the game. Trial 1 with one intervention (review charts only) completed the round in less time than Baseline 2 (blind). Trial 2 with two interventions (review charts and tutorials) completed the round in less time than Baseline 2 (blind). Playing a game tutorial (in addition to reviewing performance measures from prior trials) betters a participant s time in completing the game. Trial 2 with two interventions (review charts and tutorials) completed the round in less time than Trial 1 with one intervention (review charts only).

15 Limitations Limited number of trials: The experiment calls for a subject who has no prior experience playing the game. This limits the number of data points that can be collected from each player to one. The limited number of trials makes the results susceptible to outliers. The intervention group: There are only two intervention trials, one for chart and another for chart and tutorial. There isn t a trial to examine the possible benefits of a tutorial-only intervention. The participants in this project were part of a data mining class and had an interest in testing data results against game performance. This may not be generalizable to a broader population which does not have the same background.

16 Possible Applications The results from this project should be included in the tutorials of the game Labyrinth. Knowledge that limiting the pitch, roll, and yaw could result in improved completion time. Individuals with an interest in data and charts can alter their behavior based on data presented. The application can be to present more charts to like audiences, in order to suggest potential changes.
