  1. Preamble<\/strong><\/li>\n<\/ol>\n

    The management of a person\u2019s activity when engaged in sporting or normal daily activities is becoming<\/p>\n

    increasingly important.  Elite athletes need to monitor the proportion of time they spend running, walking or<\/p>\n

    standing still during training sessions or actual match play.  Amateurs, who are interested in fitness, may also<\/p>\n

    be interested in their activity levels.  Monitoring idleness\/walking\/running patterns is also important in the<\/p>\n

    study of some animals.<\/p>\n

     <\/p>\n

      \n
    1. The challenge<\/strong><\/li>\n<\/ol>\n

      Your team needs to develop and validate a (computer) tool to measure the time a person spends standing<\/p>\n

      still, walking or running using motion sensors (accelerometers) found in smartphones.<\/p>\n

       <\/p>\n

      Specifically, the software tool needs to be:<\/p>\n

      \u0095 Reliable and accurate<\/p>\n

      \u0095 user-friendly (that is capable of being used by any untrained person)<\/p>\n

      \u0095 able to clearly display activity graphically<\/p>\n

      \u0095 able to store data for archiving and later retrieval and viewing<\/p>\n

       <\/p>\n

        \n
      1. Deliverables and assessment <\/strong><\/li>\n<\/ol>\n

         <\/p>\n

         <\/p>\n

          \n
        1. Written report (20 marks). A description of your design and the software\u2019s operation are to be<\/li>\n<\/ol>\n

          presented in a report (one report for each team) that is laid-out as follows:<\/p>\n

            \n
          1. An introduction of the problem<\/li>\n
          2. The methodology (signal analysis techniques) that will be used to detect different motions<\/li>\n
          3. A description of the algorithm (flow chart)<\/li>\n
          4. A detailed description of your analysis software (computer code)<\/li>\n
          5. Results of validation experiments<\/li>\n
          6. Conclusion including suggestions on how to improve the detection algorithm<\/li>\n<\/ol>\n

             <\/p>\n

            This report is to be completed and submitted to your designated facilitator before 5:00 pm on Friday of<\/p>\n

            the week after completion of the project. After it is assessed, you report will be returned to you along<\/p>\n

            with comments and feedback on your effort.<\/p>\n

             <\/p>\n

              \n
            1. Test (10 marks) \u2013 Duration: 1 hour. To be undertaken during the second part of the last session for<\/li>\n<\/ol>\n

              the project.  The test is a closed-book session and is to be attempted by each student individually (no<\/p>\n

              team work allowed) \u2013 examination conditions will apply.<\/p>\n

               <\/p>\n

                \n
              1. Resources<\/strong><\/li>\n<\/ol>\n

                1. Safety & technical support<\/strong><\/li>\n<\/ol>\n

                  Although the activity and associated equipment are inherently safe, due caution must be applied especially if<\/p>\n

                  you are planning to use public spaces.  Make sure that any space you use to generate vibration data is safe<\/p>\n

                  and appropriate for the purpose.<\/p>\n
