高齡化社會將連帶的對社會和國家帶來許多的問題，例如醫療費用開銷，獨居和疾病擴大之問題。因此，在未來社會，如何改善老年人之相關議題將成為焦點。在高齡化社會中，跌倒成為了一個對老年人傷害主要的威脅。跌倒可以導致身體創傷，不僅如此也會影響老年人對跌倒的恐懼而自信心受創，不敢再嘗試一些運動，這將加劇老年人退化。
在之前，大部分研究主要都以針對肌肉骨骼方面去探討跌倒的危險因子，近期發現認知功能衰退也是導致跌倒的其中原因之一。據研究，在認知功能衰退的過程中，視覺空間關注能力在眾多非記憶認知功能中屬最先衰退的一塊。視覺空間關注能力主要協助老人在肢體運動時，執行引導步伐，動態平衡和距離判斷之作用。因此，視覺空間關注能力下降是導致跌倒的其中原因之一，一些研究也以老年人視覺空間關注能力來判斷其是否是跌倒高風險群。
老年人視覺空間關注的能力能夠透過掛關注網絡訓練的方式來改善與加強。其方式主要原因注意涉及許多不同的功能神經網絡，受試者可通過不斷重複、複習波斯納任務等，認知任務的方式改進這些一個或多個功能來提高神經網絡的效率。雖然重複做波斯納任務等認知任務可以改善視覺空間關注能力，但現有的認知任務都缺乏趣味性與互動方式，大部分的年長者都不會將其納入日常練習行程。
本研究由設計方法歸納出設計準則，並結合之擴真實境之技術與現有的認知任務結合，推出一套遊戲練習系統，協助高齡者鍛煉認知功能，改善視覺關注衰退之問題，從而減少跌倒之風險和提升高齡者生活品質。

The aging society will cause problems to the public and the country, such as extra medical expenses, solitariness and expanding diseases. Therefore, in the future society, how to improve the issues related to the elderly will become the main focus. In aging society, fall has become a major threat to the elderly which causes injury both physically and psychologically, making them not confidant and fear to fall again. This will exacerbate the degradation of the elderly.
In the past, most of the studies focused on the risk factors of falls in the musculoskeletal area. It is recently discovered that cognitive decline is also one of the causes of falls. According to research, visual-spatial attention ability is firstly affected in the process of cognitive decline among the other non-memory cognitive functions. The ability mainly assists the elderly in the exercise of stepping, performing the role of guiding pace, dynamic balance and distance judgment. Therefore, one of the reasons that cause fall is the decrease in visual-spatial attention ability. Some studies have also used the visual-spatial attention ability of the elderly to judge whether they are a high-risk group to fall. The ability to visually focus on space can be improved and enhanced through network training. The main reason to use this training is that many different functional neural networks are involved, thus, by repeating and reviewing Posner’s task and cognitive tasks, subject can improve the efficiency of the neural network. Although repetition of cognitive tasks can improve visual spatial attention, the existing tasks, however, lack of interesting and interactive ways. As a result, most of the seniors do not include them in their daily practice.
This study summarizes the design criteria by design methodology, and combines the technology of augmented reality with existing cognitive tasks to introduce a game practice system to help senior citizens exercise cognitive function and improve visual attention to recession, thus reducing the risk of falls, improving the life quality of the elderly.
