Dot2Dot Communications integrated Scalable Display Technologies to deliver a permanent, headset-free immersive environment for Alzheimer's patients — using a 20-foot curved multi-projector display and Scalable's automatic warp and blend to create seamless 180-degree visual therapy spaces in healthcare facilities.
Alzheimer's Disease is the most common form of dementia — a progressive condition affecting memory, cognition, and the ability to carry out daily tasks. As the disease advances, patients often lose connection with familiar people, places, and experiences. One emerging therapeutic approach uses immersive visual environments to reconnect patients with those memories, presenting familiar content in a way that can trigger emotional responses and provide comfort.
Dot2Dot Communications, a creative technology firm, developed an immersive virtual reality application specifically designed for Alzheimer's care environments. Working in collaboration with WishPlay — a content studio specializing in patient-specific memory content — the system presents curated video experiences drawn from the patient's own history: familiar faces, places, and moments rendered in a fully surrounding visual environment.
"The project evolved from the concept of providing visual therapy to patients who have Alzheimer's," explained Shawn O'Brien, Creative Technology lead at Dot2Dot Communications. "A colleague was working on a project utilizing virtual reality technology for visual therapies. Therapy is delivered for individuals with Alzheimer's by showing familiar individuals, places and experiences. WishPlay is curating the content for these applications. The real magic is in their content creation specific to the patient."
The earliest iterations of this therapy used VR headsets — but the healthcare context introduced serious practical obstacles.
"Previously, the healthcare facilities were utilizing VR headsets to deliver the content to the patients," said O'Brien. "The headsets required a cloth application to provide comfort to the patient. The healthcare provider had to disinfect the device between each patient to eliminate the spread of any illness. This became increasingly challenging during COVID-19 restrictions. Additionally, the devices were large and unwieldy for the patient. The concept of VR was fantastic, but it created a few challenges specific to the healthcare environment."
The response was to design purpose-built, permanent immersive rooms — dedicated spaces acoustically treated and equipped with fixed projection systems, removing the need for any wearable device. With the headset constraint eliminated, the team turned to the display architecture question: what technology could deliver a large, immersive, soft-edged video environment appropriate for the sensory needs of Alzheimer's patients?
"We designed an environment dedicated to the purpose of immersive virtual reality for Alzheimer's patients," O'Brien explained. "The permanent space enabled us to acoustically treat the space and integrate a permanent display solution. We evaluated a few different display technologies. We considered direct view LED, LCD, front projection and rear projection. Ultimately, we selected front projection because of the subtle video display. It was softer for patient interaction in this specific environment. Additionally, front projection allowed us to build larger displays."
With front projection selected as the display medium, the team faced the challenge of blending multiple projectors into a single seamless image across a curved 20-foot peripheral screen — delivering 180-degree coverage without visible seams or brightness variations.
Dot2Dot integrated Scalable Display Manager to handle the automatic warp, edge blending, and calibration across the multi-projector array. Scalable's camera-based calibration system measured and corrected the projection geometry automatically, producing a unified display without the manual alignment that multi-projector curved installations would otherwise require.
"Scalable's technology is incredible because of the user experience," said O'Brien. "You don't have to be a professional projectionist to utilize their software. Their optical sensors and cameras provide intricate details into the projector's throw. Scalable automatically calibrates the projectors based on the details gathered. Scalable is easy to use but provides a high-quality edge-blending and warping solution. Scalable's software created a seamless solution that delivered video across a peripheral 180-space projection screen."
The result is a clinical-grade immersive environment that healthcare staff can operate without specialized AV knowledge — recalibrating automatically when needed, and delivering consistent, distortion-free video therapy sessions for patients.
