[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

It should be further understood that the term "comprising" used in the specification of the present disclosure refers to the presence of the features, integers, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof. It should be understood that when we refer to an element as being "connected" or "coupled" to another element, it may be directly connected or coupled to the other element, or there may be intermediate elements. In addition, the "connection" or "coupling" used herein may include wireless connection or wireless coupling. The term "and / or" used herein includes all or any unit and all combinations of one or more associated listed items.

[0031] See also Figures 1 to 8 , Figures 1 to 8Schematic diagram of each video clip appearing in the video product for inducing cognitive impairment behavior shown in the embodiment of the present application, intercepted from one of the video frames of the video clip. The video product in this application can be a real-life shot, or it can be made using animation, special effects and other technical means. It is used to display various animation or photography scenes and various elements in the scene for the subject to watch so that the subject can make action feedback, and the action feedback is used to measure the cognitive ability of the subject; wherein, the scene in the video generally refers to the background or environment in which the video appears, etc., it can be a three-dimensional scene or a plane scene with scene depth, and the plane scene can be a simple color background, which can be fictional or real, or various environmental scenes, such as outdoor or indoor; the elements in the video generally refer to various objects, characters, colors, shapes, patterns, etc. that appear in the scene, and the elements, scenes, interactions between elements and elements, and interactions between elements and scenes are used to induce the subject to make corresponding feedback after watching. The feedback content includes but is not limited to eye movements, facial movements, limb behaviors, brain activities, etc. The eye movements can be tracked by an eye camera or an eye tracker to observe the feedback on the subject's eye behavior when watching the video product; the subject's facial expressions, limb movements, etc. can be filmed by a camera to observe the subject's overall movement behavior, and the brain activity can be monitored by corresponding EEG acquisition equipment or magnetic resonance imaging equipment.

[0032] This video product is designed to further determine whether the subject has cognitive impairment by evaluating cognitive abilities including but not limited to visual-spatial aspects.

[0033] Specifically, see Figure 1 As shown, the video product for inducing cognitive impairment behavior shown in the embodiment of the present application includes a first video clip and a second video clip for measuring the visual-spatial ability of the subject, the first video clip shows a plurality of first objects, the plurality of first objects are composed of a plurality of categories, each category includes a plurality of similar objects; the second video clip shows a plurality of second objects, the second objects are drawn with contour lines and are stacked.

[0034] This video product can be used to induce corresponding behavioral feedback, and their visual-spatial cognitive ability can be measured based on the behavioral feedback. By evaluating the visual-spatial cognitive ability of the subjects, it is possible to screen, diagnose, treat and evaluate the efficacy of cognitive disorders in the subjects.

[0035] It is known that the video product includes one or more video clips, each of which can be a static image of a single image or a dynamic video composed of multiple continuous image frames; each video clip can be used to measure one or more cognitive abilities. Each video clip is played according to the set timing, and the playback timing can be adjusted according to actual needs.

[0036] More specifically, Figure 2 and Figure 3 As shown, in each video clip in this embodiment, the first video clip shows three kinds of fruits, some of which are placed in different plates according to categories, and other parts of fruits are scattered outside the plates; when the fruits are put back into the corresponding plates according to categories, the indicator element in this embodiment is the category of the fruits. Normal people can easily place the fruits outside the plates into the plates according to the same category as expected, while cognitively impaired patients may not be able to identify the category of the fruits and do not know where the fruits outside the plates should be placed. Therefore, the subject's visual-spatial cognitive ability to recognize objects of the same category can be measured based on the subject's eye sight.

[0037] The second video clip shows the outlines of multiple objects, and the outlines of each line overlap and cross each other. The lines are used to indicate the shape of the object. For normal people, the category and shape of the object can be easily identified by the outlines, but for patients with cognitive impairment, they may only be able to identify a mess of lines. Therefore, the subject's visual spatial cognitive ability can be measured based on his or her eye sight to perceive graphics.

[0038] Thus, through the paradigm of the above two video clips, cognitive impairment behaviors for visual-spatial ability can be induced in the subjects. In other exemplary embodiments, in order to induce more cognitive impairment behaviors from more angles and enrich the applicable scenarios of the video product, more video clips can be added on the basis of the above embodiments.

[0039] In an exemplary embodiment, the video product further includes a third video clip for measuring memory ability, wherein the third video clip shows at least one target object and a plurality of distractors, wherein the distractors appear later than the target object.

[0040] like Figure 4a and Figure 4b In the video clip shown, the display part of the video clip shows a person playing with a dog with a ball. When the video clip plays to the interference part, the ball, which is one of the target elements, is thrown by the person, and then switches to Figure 4bIn a new scene, there are many objects with the same shape and / or category as the target element. Normal people can easily identify the target element or target object in a new scene, but people with cognitive impairment may not be able to remember the appearance of the target object, so that they cannot recognize the target object in a new scene with distractors.

[0041] It is important to know that patients with cognitive impairment have varying degrees of impairment in both working memory and episodic memory, and will be impaired at all stages (including encoding, storage, and retrieval), including but not limited to patients having difficulty forming new memories, difficulties in transferring information from short-term memory to long-term memory, difficulty in storing encoded information in the brain, and failure in information retrieval. Therefore, the subject's cognitive ability related to memory can be obtained by observing the subject's eye gaze area and trajectory. Preferably, by combining the evaluation results of memory cognitive ability with the evaluation results of visual-spatial cognitive ability, it is possible to further better achieve screening, diagnosis, treatment, and efficacy evaluation of cognitive impairment in subjects.

[0042] In an exemplary embodiment, the video product further includes a fourth video clip for measuring execution capability, wherein the fourth video clip displays an indicator element and a target element, wherein the indicator element is used to indicate an activity path of the target element according to a preset rule. The video clip also includes content in which the target element does not move according to the rule.

[0043] like Figure 5 As shown, the video clip shows randomly placed blocks, with corresponding number labels and point labels marked inside the blocks. The numbers and points can correspond one to one and be regarded as indicator elements. The beginning of the video shows the process of connecting the blocks according to the size of the numbers, that is, connecting number 1, point 1, number 2, and point 2 in sequence through lines, so that the connection order at the beginning of the video is used to prompt the subjects to connect in a regular manner. After the beginning part ends, the connection will be paused, and after replaying, it will be connected in a different way from the beginning part. That is, there will be a process of taking the wrong path in the connection process, or a process that does not conform to the connection rule shown in the beginning part. In such a process, it is not easy for patients with cognitive impairment to correctly perform the connection process or find the connection errors, while normal healthy people can correctly perform the connection process and can also find the connection errors in the video. Therefore, the subject's execution ability can be measured by observing the subject's eye movement fixation area and trajectory.

[0044] Figure 6As another embodiment of the fourth video clip, the video clip shows a person with a variety of tools in front of him, such as a knife, fork, comb, chopsticks, toothbrush, etc.; and items related to these tools, such as a bowl of food, an orange, etc. Among them, people and the above-mentioned related items can be regarded as target elements, and the tools placed on the table can be regarded as indicator elements, which conform to the common sense rules of general use. When the character takes the related items, a normal person can identify the tool associated with the item, so as to predict what kind of tool the task character will choose next to perform the corresponding activity; but it is not easy for patients with cognitive impairment to select the correct tool in advance. Therefore, for each task in this embodiment, multiple indicator elements are used to indicate the activity content or position of the target element. It can be examined whether the subject can complete the corresponding task according to the indicator element or the set method, and the execution ability can be measured by observing the subject's eye movement fixation area and trajectory.

[0045] In this embodiment, the video clip includes a guide part and a main part. The guide part shows the process of the target element moving according to the indication element; the main part shows the process of the target element not moving according to the position indicated by the indication element, or changing the moving route and / or pausing the movement during the process of moving according to the position indicated by the indication element.

[0046] By showing the movement pattern of the target element in the guiding part, and by suddenly changing the movement pattern of the target element or pausing and delaying the movement of the target element when showing the movement of the target element again, the subject's line of sight is deliberately induced to move in the wrong way, so as to mislead him; the line of sight of a person with normal cognition will still move according to the movement pattern indicated by the indicating element, while the line of sight of a person with cognitive impairment will follow the misleading direction or stop at the same time when the movement is paused. Therefore, by combining the evaluation results of the cognitive ability with the evaluation results of the cognitive ability measured by the above-mentioned embodiments, it is possible to further better realize the screening, diagnosis, treatment and efficacy evaluation of cognitive impairment for the subject.

[0047] In an exemplary embodiment, the video product further includes a fifth video segment for measuring language ability, wherein the fifth video segment shows at least one paragraph of text with disordered word order.

[0048] like Figure 7As shown, the video clip shows a paragraph of text with disordered word order. Patients with cognitive impairment often show a decline in language ability, including a decline in the ability to process, understand, produce and use language, which may affect one or more of comprehension, expression, reading and writing. The video clip of this embodiment can be used to discover and measure the decline in language ability of patients with cognitive impairment through prompt information such as text. This decline in language ability includes difficulty in recognizing and understanding vocabulary, difficulty in matching the correspondence between things and vocabulary, as well as a decline in the ability to read fragments, a decline in the ability to process out of order, and a decline in the ability to recognize and understand lexical syntax.

[0049] like Figure 8 Another embodiment of the fifth video clip is shown. The left side of the video clip shows a picture of an animal or insect, such as a butterfly. The right side shows multiple text labels related to the animal or insect, but only one of the text labels corresponds to the picture of the animal or insect. Due to the decline in language ability of cognitively impaired patients, it will affect their understanding and recognition of words, and it will be difficult for them to match the butterfly in the picture with the words displayed with text labels. Normal people will quickly match the text labels according to the butterfly in the picture.

[0050] Therefore, the subject's language ability can be measured by observing the subject's eye gaze area and trajectory. Combining the evaluation results of language cognitive ability with the evaluation results of cognitive ability measured in the above embodiments can further better achieve screening, diagnosis, treatment and efficacy evaluation of cognitive impairment in subjects.

[0051] In an exemplary embodiment, the video product further includes a sixth video segment for measuring alertness, wherein the sixth video segment displays a danger element, and the danger element is used to indicate that there is danger information in the video segment.

[0052] like Fig. 9 As shown in the figure, the video clip shows a person cooking in a kitchen scene, where the gas stove is burning, and the burning flame is a dangerous element. At this time, the person in the video clip leaves the scene, but the gas stove is not turned off, thus playing the scene of forgetting to turn off the fire when cooking in life. This video clip is used to examine whether people with cognitive impairment can identify potential dangers in time in life. People with cognitive impairment have decreased alertness and cannot notice the situation where the fire is not turned off, while normal healthy people will pay close attention to the burning state of the gas stove and try to look at the face of the protagonist in the video to show the behavior of trying to inform them of the dangerous situation. Therefore, the alertness of the subject can be measured by observing the subject's eye movement fixation area.

[0053] Patients with cognitive impairment often have decreased alertness, which involves changes in an individual's ability to respond to external stimuli. Although alertness can be summarized as part of complex attention, it is presented separately because patients with cognitive impairment often forget to turn off the fire and other similar behaviors, reflecting unique clinical symptoms and being closely related to a decline in self-care ability. Therefore, by combining the evaluation results of alert cognitive ability with the evaluation results of cognitive ability measured in the above-mentioned embodiments, it is possible to further better achieve screening, diagnosis, treatment and efficacy evaluation of cognitive impairment in subjects.
