In this detailed description, the subject matter invention is explained with references to examples without forming any restrictive effect in order to make the subject more understandable. Accordingly, in the detailed description and in the figures below, a computer (10) integrated coordination test device (30) is described which is providing evaluation of candidates hand-arm coordination.

With reference to Figure 1 , schematic view of test system is given. The general outlines of test system comprise a computer (10) and a coordination test device (30) which is adapted to the computer (10). The computer (10) has a processor (1 1) which is providing the coordination between elements and controlling the test system working. Also the computer (10) has a data base (12). Information as like candidate information and reference images (60) which are used in test etc. are stored in said date base (12).

With reference to Figure 2, perspective view of the coordination test device (30) is shown. The coordination test device (30) has a touch screen monitor (20) which is provided in the protective casting (31). Touch screen monitor (20) is located in the casting (31) adjacent to front wall (311) as candidate can access to it. A pillar (32) is provided on the upper face (312) of the front wall (311 ) and a ball bearing (33) group is provided on the pillar (32). A drawing mechanism (40) which is located on the front wall (311 ), is connected to the ball bearing (33) group. The drawing mechanism (40) has a fist arm (41) and second arm (42) which are connected to ball bearing (33). Both arms (41, 42) have a handles (421 , 422) which are designed suitable for human hand ergonomics. A bearing (43, 44) for each arm (41 , 42) is located on near the middle point of arms (41 , 42). Guidance sticks (45, 46) which are extending to each other, are provided in the bearings (43, 44) which are connected via spindles (431 , 441). The drawing mechanism (40) has a pen slot (47) which the both guidance sticks (45, 46) are connected to it. The pen slot (47) as like a ball bearing structure. Guidance sticks (45, 46) have freedom to rotate, in the bearings (43, 44) and on the pen slot (47), with the condition to protect parallelism according to front wall (31 1 ). Parallelism of the guidance sticks (45, 46) are provided by the bearings (43, 44). The bearings (43, 44) consist of two walls which extends parallel to each other. There is an electronic pen (50) which can be detected by touch screen monitor (20), settles in to the pen slot (47). When the electronic pen (50) moves at the test it leaves a digital scar on the touch screen monitor (20). The electronic pen (50) draws a digital line when it moves. With reference to Figure 3, top view of coordination test device (30) is shown. The drawing mechanism (40) can be rotated in a determined direction (R) and an opposite direction over the ball bearing (33) group. Each arm (41 , 42) can be rotated independently over the ball bearing (33) group. Arms (41 , 42) can be move to closing direction (D), to the imaginary axis which divides the casting in half, and opening direction (A). Depending on the arms (41 , 42) movement the guidance sticks (45, 46) movement direction therefore the electronic pen (50) movement direction changes. When arms (41 , 42) move to the closing direction (D); guidance sticks (45, 46) moves to divergence direction (U). When arms (41 , 42) move to the opening direction (A); guidance sticks (45, 46) moves to closing direction (V). When guidance sticks (45, 46) moves to divergence direction (U), the electronic pen (50) starts moving to divergence direction (F) according to upper face (312). When guidance sticks (45, 46) moves to closing direction (V), the electronic pen (50) starts moving to closing direction (E) according to upper face (312). Both arms (41 , 42) and the elements on the both arms (41 , 42) can be move independently of each other. For example; candidate can hold the first arm (41) in a fixed position and he can move the second arm (42) by this wat he can move the electronic pen (50) on the touch screen monitor (20).

With reference to Figure 6, figure 7, figure 8 and figure 9 the reference images (60) which will be used for test system is shown. Reference images (60) consist of multiple areas which have different characteristics. As an example first reference image (601) and second reference image (602) consist of a diagonal descent region (61), a diagonal ascent region (62) and a parallel region (63). Difference between first and second reference image (601 , 602) is amount and frequency of said regions. At the third reference image (603) difference from first two reference image (601 , 602) is the third reference image (603) has vertical regions (64). Fourth reference image (604) has annular regions (65). There are turning points (66) on transition zones before every region. Ail the lines which consists reference images (60), has a thickness (K). Said thickness (K) is preferably more than the thickness of electronic pen's (50) line. The line's thickness (K) at most two times of electronic pen's (50) line's thickness. The thickness (K) is equal to amount of tolerance candidate can use during the test. By this way evaluation of movements of candidates hand over the reference images (60) with inside of the tolerance amount of thickness.

Working the coordination test device (30) and applying the coordination test as it follows. Candidates can move the first arm (41) and second arm (42) opening direction (A) or closing direction (D) by this way the electronic pen (50) can move on the touch screen monitor (20). When the necessity condition candidate can move the drawing mechanism's (40) whole elements over the ball bearing (33) in this manner the electronic pen (50) can be directed over touch screen monitor (20). Candidates can move arms (41 , 42) independently; it provides electronic pen (50) can move diagonal and radial.

Before the coordination test begins the electronic pen (50) creates traces as a point on the touch screen monitor (20). Thereby candidate can learn the electronic pen's (50) location visually. The reason for this during the test the electronic pen (50) not comes into contact with the touch screen monitor's (20) surface, preferably located slightly in the air. Said distance has to less than one centimeter. At the test phase candidate moves the electronic pen (50) over the reference images (60) which appears on the touch screen monitor (20). To be more descriptive according to sample reference images (601 , 602, 603, 604) the test is applied as follows. Candidate has to lead the electronic pen (50) to starting point (B) via the drawing mechanism (40). When the electronic pen (50) reaches to the starting point (B), the firs reference image (601) appears at the touch screen monitor (20). Candidate has to move electronic pen (50) over the first reference image's (601) line than reach again to the starting point (B). When the electronic pen (50) reaches the starting point (B) again second reference image (602) appears at the touch screen monitor (20). When candidate move the electronic pen (50) over the second reference image's (601) line than reach again to the starting point (B), third reference image (603) appears at the touch screen monitor (20). The coordination test continues until the whole reference images (60) are shown at the touch screen monitor (20). The number and the difficulty of the reference images (60) are determined by the exam preparative. The regions which are used at the reference images (60), may differ by the exam preparative. Complex regions as corrugated, wavy, curvy can be added to reference images (60) to make the test harder.

During the test the processor (11) records information. Said information includes; completion time, as a second manner, of drawing the reference image (60), total completion time of test, amount of staying the electronic pen (50) in line thickness of reference image (60), amount of staying the electronic pen (50) in line center line of reference image (60) etc. According to recorded information processor makes placement of candidates. This placement is made according to average score. If necessary, in specific positions officer can get detailed information. By this way candidate can placed different parameters.
