  2. A small introductionWhat is ADHD?Attention deficit hyperactivity disorder • ADHD is a problem with inattentiveness, over-activity, impulsivity, or a combination. For these problems to be diagnosed as ADHD, they must be out of the normal range for a child's age and development. • ADHD is the most commonly diagnosed behavioral disorder of childhood. It affects about 3 - 5% of school aged children. ADHD is diagnosed much more often in boys than in girls.

  3. Signs and Symptoms The symptoms of ADHD fall into three groups: • Lack of attention (inattentiveness) • Hyperactivity • Impulsive behavior (impulsivity) Most children with ADHD also have at least one other developmental or behavioral problem. They may also have a psychiatric problem, such as depression or bipolar disorder.

  4. So, who needs to be focus? • People diagnosed with ADHD • People with suspected ADHD • Teachers who have students with ADHD • Just regular people who want to check the level of their attention and concentration

  5. The application:Main objective • The application attempts to diagnose ADHD in a person through the analysis in two different levels: • Diagnosing ADHD using diagnostic user's movement, processing and rendering the results, and creating a graph that allows the user to receive a personal score. • Diagnosing ADHD using specials tests - reading comprehension, games and puzzles that require a high level of attentiveness and punctuality.

  6. How to use the application When the application opens it have a main menu, in which there are 5 options: • Click to login – if a user has already registered and want to login. • About Bfcous – gives a short explanation about the application purpose and how to use it. • Signup – allow the user to sign up and open a new account. • Start monitor – a “quick start” of the application (without the need to register). • puzzles and fun stuff - games and puzzles that require a high level of attentiveness

  7. Signing up When a user first enter the application it is recommended that he will sigh up. This can be done by pressing the sigh up button from the main menu. After pressing the “Signup” button the user is directed to the signup screen and required to choose a user name and password. If the selected name already exist the user will get the message “Name already in use. Please chose another”.

  8. Log on After having an account the user can log in to his\her account by clicking the “Click to login” button, which lead him\her to the screen on the left. Where he will need to be identified by inserting his user name and password. If one them is incorrect he will get an informative error message.

  9. Main menu after login After the user name was successfullyloged into the application, he will see a different main menu from before. The three new changes are: • The “Hello User Name!” message on the right. • The “Click to logout” (to exit). • The “See history” button (the second button, replace the signup).

  10. The BfocusMonitoring (1/3) Introduction: How does theaccelerometer reads data? The accelerometer gets movement info from the user in 3 dimensional planes: The X plane (“red”, which is the horizontal), the Y plane (vertical, “green”), and the Z plane (how far is the screen from our face, “blue”).

  11. The BfocusMonitoring (2/3) When the user press “Start monitor” button he will get to the screen on the left - the “Bfocus monitoring” page. To activate and start a new session of monitoring the user need to press on the “Start/Pause” button on the buttom. After that, a timer will be started and on every second that passes, the application will calculate the change in movement in all of the 3 dimensional planes, by doing a “Delta”. for example, on the X plane: DeltaX(t)=X(t)-X(t+1) (where t stand for time). For instance in this picture The user held the phone in X(0:44)=0 and move it after a second to X(0:45)= 1.39 hens the change is 1.39.

  12. The BfocusMonitoring (3/3) The Maximus of all the deltas will be placed as Max change. When the user wants to finish the monitor session he will have to press on the “Finish” button. After that the data is automatically stored on the device, and the user is getting an informative message box.

  13. Viewing history The user can see it history on any time by clicking on the “See history” button. The output looks like this: 10.3.13, avg_x_change: 0.02, avg_y_change: 0.21.avg_x_change: 0.11, avg_max_change: 0.16, time: 10:12. Which means that in 10.3.13 there was a 10:12 minutes session on which the averages changes in movement were as above.

  14. But wait… What can be done with all this data? • A lot! • All of the data that is stored can be use to track a progress of a person who has attention disorder (for example by seeing how well he is doing on the first the day, and a week later, if during that time he received a medicine such as Ritalin). • The monitor can be use for someone who wants a basic and free test to see whether or not he is suffering from attention disorder (diagnostic side). • Because of the small size of the phone the user can put it in his pants pocket, in he jacket or any other place and by that - testing different areas on the body. • Statistic value. All the information can be collected from different people and we can compare between groups of people and test if there are any abnormalities amongst different types of people.

  15. Diagnosing using tests • Diagnosing ADHD is done by several important tests: • Reading comprehension test - Analyze the difficulties of understanding and analysis of the language by user • Punctuality test - Examines the rate of reading, writing and understanding of the user by measuring the performance time • Concentration test - Examines the degree of attentiveness and concentration of the user while performing various operations
