本研究的目的是调查混合现实系统在虚拟操纵饮食体验和促进老年参与者增加食物摄入量方面的潜力。在接受护理服务的老年人中，社会孤立往往与营养不良有关。将真实元素和虚拟世界相结合的混合现实系统，可以方便地让老年人在家里吃饭的同时，通过虚拟化身在虚拟环境中体验与朋友的对话。一项针对30名年长参与者的研究调查了在客厅与熟悉的人一起或没有熟悉的人一起吃饭的混合现实幻觉是否对用餐体验和增加能量摄入有积极的影响。结果并没有显示出能量摄入的任何显著变化，但强调了虚拟客厅有一个更有活力和愉快的氛围，与在真实实验室环境中吃的食物相比，在虚拟房间里吃的食物被认为质量更高。一边吃东西一边和三个远方的朋友进行虚拟社会互动，会降低孤独感，并产生积极的情绪变化。本文还讨论了能量摄入没有增加的原因。
The aim of this study was to investigate the potential of mixed-reality systems to virtually manipulate the eating experience and facilitate increased food intake among older participants. Social isolation is often associated with undernourishment among older adults receiving care services. Mixed-reality systems that blend real elements and a virtual world can conveniently allow older adults to eat a meal in their home while experiencing having a conversation with friends through virtual avatars in a virtual environment. A within-subjects study on thirty older participants investigated whether the mixed-reality illusion of eating in a living room with and without familiar others contributed positively to the meal experience and increased energy intake. The results did not display any significant changes in energy intake but highlighted that the virtual living room had a more energetic and pleasant atmosphere and that meals eaten in the virtual room were perceived to be of a higher quality compared to meals eaten in the real lab environment. Eating while engaging in avatar-based social interactions with three remotely located friends resulted in lower sensations of being alone and positive mood changes. A discussion of the reasons for the absence of increases in energy intake is included.
