In a groundbreaking study that brings hope for the independence of individuals living with mild dementia, researchers from New Jersey Institute of Technology and Clemson University are embarking on a transformative project. Led by Alisha Pradhan and Emma Dixon, this initiative is backed by a three-year National Science Foundation grant amounting to $600,000. The essence of their research lies in the potential of assistive technologies to evolve alongside the cognitive and physical changes experienced by individuals as dementia progresses.
Pradhan emphasizes that dementia does not merely affect cognitive faculties; it can also alter physical abilities. For instance, a person might find it manageable to read a text in 12-point font during the day, but by evening, may require a larger font due to cognitive fatigue or shifts in vision. The researchers aim to develop technology that adapts to the fluctuating needs of users, thereby facilitating their independence as their conditions change over time. This focus on adaptability is crucial in ensuring the longevity of assistive technologies in the lives of those affected by dementia.
A significant part of the research involves understanding how people with cognitive impairments navigate their environments. Pradhan recounts an inspiring interview with an individual living with dementia who trained his dog to respond to commands from an Amazon Alexa device, which reminded the dog when to fetch medication. This illustrates the resourcefulness of affected individuals as they customize their living spaces and interactions with technology to enhance their quality of life.
The research project will be conducted in three distinct phases. During the initial phase, the team will engage in qualitative interviews to gain insights into the specific contexts wherein older adults with cognitive impairments require assistance. This foundational understanding will guide the subsequent phases of the project, ensuring that the development of assistive technologies is closely aligned with the actual needs and preferences of the target population.
Once the contexts have been established, researchers will enter the co-design phase, collaborating with users to create tools that modify everyday objects to provide the necessary assistance. An important aspect of this phase is the generation of training materials designed to empower users to effectively use and adapt the technologies. Pradhan’s team has already conceptualized various prototypes, such as a doormat designed to remind users of essential items to take when leaving the house and a plant holder that sends alerts when it’s time to water the plants. These prototypes will serve as examples to inspire creativity in users, encouraging them to think about how customizable assistive technology could further enhance their independence.
Pradhan expresses cautious optimism for the project, noting that many components necessary for creating adaptable assistive technologies are readily available today. Simple sensors and microcontrollers can be sourced easily from online retailers, making the potential for DIY solutions more accessible. The goal is to create training materials that can be disseminated widely, empowering anyone, including individuals affected by dementia, to develop their own assistive technologies suited to their personal needs.
The research is also noteworthy for its broader implications within the field of technology design. Pradhan highlights the need for developers and researchers to be cognizant of the diverse needs of consumers, particularly those who may experience different challenges based on age, cognitive ability, or physical limitations. For instance, she points out that most voice recognition systems are primarily designed using data from younger individuals, which might lead to inaccuracies for older users who exhibit distinct speech patterns. This underscores the necessity for inclusive design practices that consider the variances in user experience across different demographics.
Moreover, the mental health aspect of dementia presents another critical layer to the research. Pradhan notes that individuals with dementia often face heightened risks of depression, emphasizing the importance of assistive technologies that not only facilitate physical tasks but also support mental well-being. Customized technology that adapts to personal needs can enable users to engage in meaningful activities, fostering a sense of purpose and reducing feelings of isolation.
The collaboration extends beyond Pradhan and Dixon’s efforts, as other researchers at NJIT engage in various projects aimed at supporting senior citizens. For example, Michael Lee is promoting coding education for older residents of Newark, helping them acquire valuable skills that can enhance their technological literacy and empower them to take charge of their digital interactions. Additionally, David Lubliner is pioneering a course in geriatric engineering, emphasizing the importance of designing technology solutions that cater specifically to the aging population.
At NJIT’s Murray Center for Women in Technology, initiatives such as inviting industry leaders like Chitra Dorai to speak on the use of AI in addressing neurodegenerative disorders signify a growing awareness and responsiveness to the complexities of aging and cognitive decline within the tech community. These efforts collectively contribute to an evolving dialogue around how technology can be tailored to foster independence and enhance the quality of life for older adults and those grappling with cognitive challenges.
Ultimately, Pradhan reflects on the frequent disconnect between what researchers assume about the needs of people with dementia and actual user preferences. Past experiences have shown that even well-intentioned technologies may fail to gain traction due to a lack of consideration for the genuine interests and habits of users. The emphasis on involving users in the design process, giving them agency to shape their assistive systems, is essential to developing effective solutions tailored to their realities.
As research in this space evolves, it stands as a reminder of the importance of empathy and user-centric design in creating technologies that can profoundly impact lives. Every effort to understand the individual needs of those living with dementia, to involve them in the innovation process, and to adapt technologies to meet their varying circumstances plays a significant role in enhancing their autonomy and dignity.
Through the combination of innovative design, user engagement, and an understanding of the complexities of dementia, the future could hold promising advancements in assistive technologies that empower individuals to thrive in their everyday lives. The journey toward effective and adaptable assistive solutions is both a challenge and an opportunity, as researchers and developers alike reconceptualize how technology can serve the most vulnerable among us.
