Description
Technical Field
The invention relates to the field of virtual reality, in particular to a method and a device for improving cognitive ability of old people through a VR-based multitask training game.
Background
The brain has some degree of plasticity throughout life (Hubener and bonhoefer 2014). Plasticity of the brain means that the structure and function of the brain can change with changes in the surrounding environmental stimuli (Takesian and Hensch 2013). In general, adult human brain plasticity potential is in a state of dormancy, but this state of dormancy can be disrupted by specific, regular sensory or sensory-motor stimulus inputs, activating the cortical plasticity potential (Hubener and Bonhoeffer 2014). Researches show that the structure and the function of the brain of the old can be changed by long-time and regular cognitive training, so that the cognitive decline speed of the old is reduced, and the aim of improving the cognitive ability of the old is fulfilled (Joubert and Chainay 2018). Cognitive training is based on the assumption that brain function decline and cognitive decline from aging can be slowed by cognitive training (neuronal plasticity) and repeated exercise for a particular cognitive function, such as memory, attention, executive control, etc.
In recent years, research shows that the electronic game can be used as an effective cognitive training mode for improving the cognition of the old. Furthermore, the electronic game has both interest and motivation, so that cognitive intervention by means of the electronic game can cause high compliance of the elderly (Boot, Champion et al.2013). In general, electronic games have an elaborate game design style, a pleasant feeling and a challenge, and simultaneously provide a player with a reward mechanism including positive and negative feedback at an appropriate time, thereby increasing the enthusiasm of players for playing the games.
The VR technology is used for generating a virtual world of a three-dimensional space by utilizing computer simulation, providing simulation of senses such as vision, hearing, smell, touch and the like for a user, enabling the user to feel personally on the scene, and observing objects in the three-dimensional space in real time without limitation. Electronic games are very interactive, immersive and fanciful, enabling players to immerse in the world of the game and enjoy the game. Immersion, interactivity and imagination by VR technology are the most excellent so far (
et al.2017,Perez-Marcos,Bieler-Aeschlimann et al.2018,Tieri,Morone et al.2018)。
In the prior art (Li x., et al., (2020)), a virtual reality technology-based animal feeding game is designed to train the cognitive ability of the elderly. The game requirement is that the animals present are fed as they drill out of the hole (apple). When the player sees the animals as drilling out of their respective holes, they are required to move the corresponding body part to feed the animals with apples. In the specific game operation process, firstly, a billboard is integrated on the back background of the whole game, and the billboard is randomly displayed in different colors (such as red, blue, green and the like) and different shapes (such as squares, triangles, diamonds and the like). During the game, the player is required to switch between the animal and the billboard with attention. During the game, if and only if the billboard is a green triangle, the player must move the body in a different way — the player needs to first step to the right and then move the body according to where the animal appears. For billboards of other colors or shapes, the player is required to step to the left and then move his body as required.
The game training result indicates that the game has the following two problems: the game difficulty is too simple. Although 5 different difficulty levels are designed, the cognitive ability level of the old is still not well reflected, and the ceiling effect is easy to occur in the training process. Therefore, even if the elderly are subjected to long-term cognitive training, the improvement in cognitive ability of the elderly is limited. 2) The Dual-tasking design (Dual-tasking) in games has design defects. In the game mission design process, in order to realize the double-mission cognitive operation, the player needs to switch attention between the animal and the billboard. However, the two tasks (billboard and animal position) are performed in separate steps, which is different from the two-task design in the conventional two-task paradigm of psychology.

Detailed Description
First, a flow of a method for improving the cognitive ability of the elderly based on a VR-based multitask training game according to an embodiment of the present invention is described with reference to fig. 1. As shown in fig. 1-3, the method comprises the steps of:
step S101: configuring a Stroop task and a Simom task;
step S102: based on the Stroop task and the Simom task, dividing functions of the VR game system;
step S103: and the user enters the VR game system and trains through the game.
The step S101: configuring a Stroop task and a Simom task, wherein:
in the embodiment, the combination of the Stroop task and the Simon task in the game is realized by presenting the positions and the presenting modes of the squares and the fonts, and as shown in fig. 2, the specific realization of the game is realized by presenting 4 Chinese characters and 4 squares and operating a handle. The four fonts are respectively: red-colored, "red" words, "blue-colored," red "words, and blue-colored" blue "words; the four squares are respectively: a square with a "red" character written in red, a square with a "blue" character written in blue, and a square with a "red" character written in blue.
In the game operation process, a user has a red light sword in the VR space corresponding to the left hand handle and a blue light sword in the VR space corresponding to the right hand handle. The mode for combining the Stroop task and the Simon task is that the font and the square with the font are displayed to the user, the meaning of the font can represent the color, when the font and the square with the font are presented to the user, the font is displayed with the color,
(1) under the condition of the color judgment task, presenting fonts to a user; the user needs to judge the color added to the displayed font and ignore the meaning of the font. The judgment method is as follows: red light swords can only cut red-colored fonts, for example, red-colored "red" words and red-colored "blue" words; blue swords can only cut blue-colored fonts, for example, blue-colored "red" words and blue-colored "blue" words.
(2) Under the condition of word meaning judgment, presenting a square with a font to a user; the user needs to judge the meaning of the font itself and ignore the additional color of the font. The judgment method is as follows: the red light sword can only cut squares with red characters, for example, the red characters written by red color and the red characters written by blue color; blue light swords can only cut squares with blue characters, for example, red-colored "blue" characters and blue-colored "blue" characters.
(3) Under the condition of mixed judgment, both fonts and squares are presented, but a user needs to judge the colors added to the displayed fonts and ignore the meanings of the fonts; it is also necessary to judge the word meaning of the font itself in the square with the font, and ignore the additional color of the font.
The game realizes the combination of the Stroop task and the Simon task in the game by presenting the position and the presentation mode of the square and the font. Specific examples thereof include: in the color judgment task, when the red character written by red color appears on the left side, and the blue character written by blue color appears on the right side, the consistent color and character meaning are consistent with the consistent effect in the stroke task, and the red square block appearing on the left side needs a left-hand light sword, and is consistent with the position consistent effect in the simon task. If the "red" word written in blue appears on the left side and the "blue" word written in red appears on the right side, the "red" word written in blue and the "blue" word written in red merge the inconsistent effects in the task; while a blue-written "red" appearing on the left requires right-handed blue sword slash, consistent with the positional disparity effect in simon.
In this embodiment, the VR game is a music-based hit game lightswing based on VR technology. The general idea of the game design is to combine the classic psychological research paradigm, i.e. the Stroop task and the Simom task, with the VR technology, and design and develop VR games which are mainly used for training the old to execute the control capability. The Stroop task is one of the studies and gold standard for performing control. In the standard color-word Stroop task, a word written in ink of a certain color is tried to be viewed, and the task is to determine the color of the word and to characterize the dimension relevant to the task, while ignoring the meaning of the word or the reaction it causes, i.e. ignoring the dimension irrelevant to the task. Due to conflicts arising from inconsistent task-dependent and task-independent dimensions, the subject needs more attention control to determine the color of the uncoordinated stimulus than the neutral stimulus to overcome the interference at different perception and sensing and response selection stages, manifesting as a decrease in accuracy with slowing of the response speed. Simon's task is another classical paradigm for studying attention control, primarily for studying stimulus and response incompatibility effects. In this task, incompatible attempts require that the responses being tried to be made are spatially inconsistent with the orientation of the stimulus presentation, e.g., right hand versus left hand stimulus responses. The present game design combines the Stroop task with the Simon task, while manipulating the stimulus and stimulus cooperativity and the stimulus and response cooperativity, exploring task conflict resolution under attention control.
In the game process, different types of squares appear along with music rhythm in a VR scene, and a player needs to wave handles of left and right hands to hit the squares according to game rules. The higher the number of hits, the higher the score. After the game is over, the players are ranked according to the player scores, and the rank of each player appears on the ranking list.
As shown in fig. 3, the step S102: based on the Stroop task and the Simom task, performing function division on the VR game system, wherein:
based on the Stroop task and the Simom task, determining that the VR game system has the functions of music setting and game setting, and dividing the function of the VR game system into a music setting module, a game setting module and a data storage module;
the music setting module is used for editing songs and presetting the appearance frequency and the style of the blocks;
the game setting module is used for setting game scenes, light sword interaction, display interfaces, and speed and special effects of character block configuration; the game scenes comprise static scenes and lamplight rendering scenes; the optical sword interaction comprises configuring a connecting handle and setting a main camera; the display interface has the functions of selecting a game player, selecting a game song, selecting a game mode, selecting song difficulty, starting a game and returning to the previous level; the selecting game player inserts a user list by using UGUI for selecting a player; the connecting handle is divided into a red handle and a blue handle;
the game storage module is used for recording the specific data of each game of each player.
In this embodiment, the music setting module is used as a leader part of game design, and the occurrence frequency of the blocks and the types of the blocks are set in advance, so that the difficulty of game setting is reduced. The game setting module is used as an important link of game design, each step of the game is designed in detail, and all functions of game operation are completed by the game setting module; the data storage module records the specific data of each game of each player.
As shown in fig. 4, the step S103: the user enters the VR gaming system, trains through the game, wherein:
the user selects a player by selecting a game player function; selecting a game mode, wherein the game has a color mode, a word meaning mode and a mixed mode, and the color mode is to judge whether a target is hit by using a red handle or a blue handle according to the color of a block; the word sense mode is to judge whether to hit the target by using a red handle or a blue handle according to the word sense; the mixed mode needs the user to judge, the target with the black background plays the game according to the word meaning, and the target without the background plays the game according to the color; selecting a song by a user; the user selects the game difficulty, and the game sets four modes: simple version, normal version, difficult version and expert version; and the user enters the game of the next difficulty according to the grading result.
In the embodiment, thirty songs which are in the earliness of the old are edited for selection; if the user has a previous difficulty rating of A/B, the game of the next difficulty can be played.
In the embodiment, when a user selects a game player, the background is connected with the database to record the game player; after a user selects a game song, a background is connected with a song file, the song file is edited according to the game difficulty by adopting a MediocreMapper in Best Saber according to the song file and the game difficulty, and character blocks and positive and negative hands are marked according to the game difficulty and the song tempo; after the game is finished, the database is connected to record game data, and the game result is graded.
In this embodiment, five levels are set, A, B, C, D, E from high to low.
In order to detect the effectiveness of the VR game invention, 38 old people are recruited as VR game training objects to carry out game training. All 38 elderly were healthy elderly, aged 60-79 years. The test study is an experimental study involving the use of in-test designs. The specific training scheme is that for each elderly person to be tested, VR game training is performed 20 times in total. The training is carried out once every other day, the training time is 30 minutes for each time, and the training is carried out for 2-3 minutes for each 10 minutes, and 3 times for each time.
Before formal training, the game difficulty level which can be controlled by each old person is evaluated, and the method of manually adjusting the game difficulty is adopted, so that the old person can select the difficulty level suitable for himself.
VR game training field not less than 5 x 5m2And any obstacle in the field at noon enables the old to walk freely in the game process. When the game is trained every time, a worker is arranged to give guidance for accompanying, so that the safety of the old in the game process is ensured.
Within one week before VR game training begins, performing baseline test on the executive control capability of the old by using a behavioral experiment Stroop task, and collecting the reaction time and accuracy after the experiment is completed. Within a week after the end of 20 VR game sessions, the elderly were also tested using the Stroop task, while the reaction time and accuracy of the completed experiment were collected. Statistical analysis of the response time and accuracy of the Stroop task before and after training was performed using paired t-test.
Experimental results show that in color, meaning and mixed training mode, VR games significantly reduce the response of the elderly in completing the Stroop task (color training mode: t)112.9, p is 0.01; word sense training mode: t is t122.25, p is 0.04; hybrid training mode: t11 ═ 3.02, P ═ 0.01).
