DETAILED DESCRIPTION

(9) The present invention will be described with respect to particular embodiments and with reference to certain drawings but the invention is not limited thereto but only by the claims. The drawings described are only schematic and are non-limiting. In the drawings, the size of some of the elements may be exaggerated and not drawn to scale for illustrative purposes.

(10) In practice, three markers (i.e., shoulder marker, elbow marker and hand marker) are necessary to be used in conjunction with the movement tracking system for persons suffering from upper limb dysfunction. However, since the present invention does not relate to the improvement of the hand marker and the improvement of the garment carrying the hand marker, the hand marker-related garment will be omitted and the training garment for the shoulder marker and the elbow marker will be described in detail in the following.

(11) FIG. 2 shows a shoulder garment 10 in a training garment in accordance with an embodiment of the present invention.

(12) As shown in FIG. 2, the shoulder garment 10 basically comprises two portions, i.e., a shoulder portion 11 and a main body portion 12. In order to be distinguished from the main body portion of the elbow garment (which will be described in the following), the main body portion 12 of the shoulder garment 10 is referred to as the first main body portion 12 hereinafter. Accordingly, the main body portion of the elbow garment will be referred to as the second main body portion.

(13) The shoulder portion 11 of the shoulder garment 10 is adapted to be worn across a shoulder of the person, as shown in the left figure of FIG. 3, which shows the posture of a person wearing the shoulder garment 10 in a still state. Further, the first main body portion 12 is adapted to be worn around the trunk of the person, as shown in the left figure of FIG. 3. Although in FIG. 3, the first main body portion 12 is shown as being worn around the chest of the person, another part of the trunk could also be possible. For example, the first main body portion 12 may be worn around the waist of the person.

(14) In the case of the shoulder garment 10 of the present invention, both ends of the shoulder portion 11 are attached to the first main body portion 12. Although in the present embodiment shown in FIG. 2, the shoulder portion 11 and the first main body portion 12 are formed as one piece to implement the attachment between the shoulder portion 11 and the first main body portion 12, it will be readily understood by the person skilled in the art that the attachment is not only limited to this design. For example, the shoulder portion 11 may be attached to the first main body portion 12 by connection mechanisms, such as fasteners, or stitches, as long as these two portions are fixed together.

(15) Furthermore, as shown in FIG. 2, the shoulder portion 11 has an area 101 for receiving a shoulder marker, which is shown as the dot in FIG. 3. In the embodiment shown in FIG. 2, the area 101 is provided with a VELCRO hook and loop fastener to attach the shoulder marker. However, it will be readily understood by the person skilled in the art that the attachment is not only limited to this design, but may be implemented by other connection mechanisms known in the art.

(16) In addition, since the stature of patients may vary, the shoulder portion 11 in the shoulder garment 10 according to the present invention is designed to be adjustable to make sure that the shoulder marker can be positioned near the shoulder joint of the specific patient.

(17) In the embodiment shown in FIG. 2, the first main body portion 12 has two ends, one of which is provided with a strap 13 to be attached to the other end in order to fixate the first main body portion 12 around the trunk of the person. In an example, the strap 13 is adapted to attach the first main body portion 12 by a VELCRO hook and loop fastener.

(18) Please note that, as can be easily understood by the person skilled in the art, the first main body portion 12 may not be provided with said strap 13. Instead, the first main body portion 12 may be an elastic unitary portion to be put on by the person. In another example, the first body portion 12 may have two ends and both ends are connected with each by other connection mechanisms, for example, fasteners, a VELCRO hook and loop fastener.

(19) The materials used for the shoulder portion 11, the first main body portion 12, and the strap 13, may be the same or different. For example, soft and elastic material, such as EVA, may be preferred. However, other materials may also be feasible.

(20) As shown in the right figure of FIG. 3 showing the posture of the person when he raises his arm, due to the special design of the shoulder portion 11 and the first main body portion 12, i.e., a shoulder harness-like design, the shoulder portion 11, where the shoulder marker is attached, is fixed to the first main body portion 12, which is fixedly worn around the trunk of the person.

(21) Therefore, the proposed shoulder garment 10 can prevent displacement of the shoulder marker while the person is performing active rehabilitation exercises, such as raising up his arm, and therefore, it can improve the recognition accuracy of the movement tracking system for the rehabilitation training

(22) FIG. 4 shows a training garment 1 in accordance with an embodiment of the present invention, which further comprises, in addition to the shoulder garment 10, an elbow garment 20. The elbow garment 20 in the present embodiment is separate from the shoulder garment 10.

(23) The elbow garment 20 shown in FIG. 4 comprises a second main body portion 21 adapted to be worn around the upper limb of the person and an elbow marker 22, which is attached to the second main body portion 21 of the elbow garment 20 and which is adapted to be worn around the upper limb of the person near the elbow joint.

(24) In this design, since the elbow garment 20 is separate from the shoulder garment 10, the independent elbow garment 20 ensures correct and specific calibration, because the elbow marker 22 can be accurately fixed at or near where the elbow joint is positioned, so that the movement tracking system can figure out the specific distance between the shoulder marker and the elbow marker 22 (as shown in FIG. 4). The elbow garment's individuality instead of attachment to the shoulder garment 10 removes the need for patient or caregiver to adjust its position correctly.

(25) Therefore, in this aspect, not only the shoulder marker's displacement can be prevented, but also the elbow marker 22 can be accurately fixed. Accordingly, the recognition accuracy of the movement tracking system may be further improved.

(26) FIG. 5 schematically shows the elbow garment 20 in accordance with a preferred embodiment of the present invention.

(27) In this embodiment, unlike the conventional elbow garment, the second main body portion 21 of the elbow garment 20 further comprises a locating hole 23 for receiving the elbow joint of the person. FIG. 6 shows the detailed posture of the elbow when the person wears the elbow garment 20 shown in FIG. 5.

(28) In this design, the locating hole 23 in the elbow garment 20 may ensure both wearing accuracy and recognition accuracy. The locating hole 23 may function as a mark designed especially to inform the person as to how he should wear the elbow garment 20, i.e. placing the elbow joint in the locating hole is the only right way to wear the elbow garment 20 (as shown in the left figure of FIG. 6). In this way, it helps the person to fixate the elbow marker 22 in the right position.

(29) Furthermore, in this way, more of the elbow marker's external superficial area becomes exposed instead of being hidden from view(?) by the elbow joint (see the left figure in FIG. 6), as compared to the conventional elbow garment shown in the right figure of FIG. 6. Accordingly, this can further improve the recognition accuracy.

(30) The materials of the second main body portion 21 and the elbow marker 22 may be the same or different. For example, soft and elastic material, such as EVA, may be preferred. However, other materials may also be feasible.

(31) As mentioned above, the training garment 1 according to the present invention will be applicable for rehabilitation training of persons suffering from upper limb dysfunction, in particular, patients who survived neurological diseases like e.g. stroke or after brain surgery and orthopedic procedures.

(32) Specifically, the procedure for wearing the training garment 1 according to the present invention may be as follows, but is not limited thereto:

(33) 1. To put on the shoulder garment 10, pass the affected arm through it and adjust the adjustable shoulder portion 11 to make sure the area 101 for the shoulder marker is just near the shoulder joint;

(34) 2. Press the strap for the shoulder marker to attach it tightly to Velcro on the area 101 of the shoulder garment 10;

(35) 3. Pass the affected arm through the elbow marker 22, making sure that the locating hole 23 is positioned at the elbow joint, and then fixate the strap for the elbow marker 22 tightly on the arm just above the elbow joint.

(36) As can be seen from the above, the training garment 1 according to the present invention may improve the recognition accuracy of the movement tracking system for the rehabilitation training, and therefore is suitable for the early-stage patients. Moreover, the training garment 1 is also very easy to put on for a patient, especially the elbow garment 20 shown in FIGS. 5 and 6; therefore, it may be used for the later-stage patients as well.

(37) Please note that, as mentioned above, the detailed design of the training garment 1 according to the present invention should not be limited to the design mentioned above. It will be apparent to those skilled in the art that the various aspects of the invention claimed may be practiced in other examples that depart from these specific details.

(38) Furthermore, the mere fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measures cannot be used to advantage.

(39) It should be noted that the above-mentioned embodiments illustrate rather than limit the invention and that those skilled in the art will be able to design alternative embodiments without departing from the scope of the appended claims. In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim. The word comprising does not exclude the presence of elements or steps not listed in a claim or in the description. The word a or an preceding an element does not exclude the presence of a plurality of such elements. In the system claims enumerating several units, several of these units can be embodied by one and the same item of software and/or hardware. The usage of the words first, second and third, et cetera, does not indicate any ordering. These words are to be interpreted as names.
