Lumeen is an innovative medical device which uses virtual reality for social and therapeutic purposes for dependant elderly people. Our immersive mediation device enables the elderly to escape for a short moment by swimming with dolphins, contemplating the Northern Lights, crossing Provence, revisit a neighbourhood etc. Those privileged moments improve well-being and calm seniors. They create social link, fight against anxiety and facilitate reminiscence and cognitive stimulation. Virtual reality has proved its efficiency in a lot of clinical testing for more than 30 years. We adapt our technology to the needs and uses of the sector by making it simple and accessible. In one year, we have equiped more than 150 EADOP (Establishment of Accommodation for Dependant Old Persons), autonomy residences and NHCS (Nursing Home Care Services), located in France. We design and evaluate our programs with French UHC (University Hospital Center) such as Hospices Civils de Lyon and Paris hospitals. Today, we open to other publics and aim to become the leader of new immersive therapies on the market.
