Integrating Advanced Technology, Additive Manufacturing for Better Accessibility

Equipment, software and product systems that are used to increase, maintain or improve the functional capabilities of persons with disabilities make up the umbrella term “assistive technology”. In this market, breakthroughs in 3D printing have streamlined workflows and changed time-sensitive processes into rapid solutions.

This progress in additive manufacturing has allowed for complex geometries to be produced on-demand, and in the case of one collaboration, is benefiting individuals with neurogenerative diseases or severe motor disabilities. JIB and Sculpteo are working together to provide a device that integrates an eye camera with a tablet and custom case for user interaction with technology.

The Companies Behind the Innovation

JIB, co-founded by Thomas Groell, focuses on bridging the gaps between technology and disabilities. With a mission to adapt mainstream technology for individuals who require specialized solutions, JIB has navigated the complexity of environmental control and communication for those with physical limitations. The company’s journey began more than six years ago with the goal of providing adaptive technologies and solutions to individuals who find themselves marginalized by conventional tech products.

Sculpteo, led by CEO Alexandre D’Orsetti, is a 3D printing service provider established in 2009. Sculpteo began with the aim of democratizing industrial additive manufacturing via an online platform, which subsequently expanded to focus on several verticals, including medical applications. By offering design support and advanced production capabilities, they play a role in the rapid development of new, user-centric assistive technologies.

The Device and Its Benefits

The collaborative output of JIB and Sculpteo is a tablet-based communication device that utilizes eye-tracking technology specifically designed for individuals who are unable to communicate verbally or utilize traditional input methods. The device functions by interpreting the user’s eye movements, allowing them to navigate interfaces and interact with their environment using pictograms or a virtual keyboard.

This not only empowers those with severe motor disabilities but actively enhances their quality of life by facilitating communication with caregivers and family members. Children, for instance, benefit from augmentative and alternative communication (ACC) systems, which assist in language learning and social interaction through intuitive pictograms.

Design and Development Challenges

One of the core challenges in developing this device was the integration of the eye-tracking system with varying tablet types. Because many users employ different tablets, it was necessary to design a flexible casing that could adapt to the dimensions and configurations unique to each model.

As Groell said, the design must account for the frequent updates and changes in tablet models, requiring continuous revisions to create a casing that fits perfectly and supports the eye-tracking technology’s functionality.

Each adaptation is made feasible through the capabilities of 3D printing, allowing Sculpteo to produce customized designs on-demand. This flexibility not only supports production but also addresses the specific needs of each user without necessitating large inventory stocks.

Tech Integration and User Experience

The hardware integration of the eye tracker and tablet effectively allows for real-time communication. The eye tracker, located beneath the tablet and enclosed within the casing, connects to the tablet through a hub that facilitates peripheral connections. This design ensures that user experience remains seamless, allowing individuals with disabilities to interact with the device intuitively.

The software is important to the success of this technology; the combination of firmware from the eye tracker supplier and additional communication software developed by JIB creates a cohesive interface tailored to users’ unique interaction patterns. This is especially significant for those who cannot utilize traditional input methods, as the gaze-based navigation system requires interfaces designed specifically for eye tracking.

The materials used to create the case needed to be adaptable and resilient, so the device shell is produced using thermoplastic polyurethane (TPU), which offers flexibility and durability. D’Orsetti says that TPU is resistant to abrasion, which is essential for devices used in environments like medical institutions, where robustness is vital.

Future Direction, Impact

Looking ahead, JIB and Sculpteo are committed to further refining their product offerings. Plans include developing new prototypes that integrate additional features such as enhanced battery life and audio outputs, which are particularly beneficial in educational settings where external noise may be a factor.

The partnership shows how innovation can create meaningful change in the lives of individuals with disabilities. Their focus on user-centric design and adaptability shows the potential of collaborative efforts in tackling barriers faced by underserved populations in today’s tech landscape. As the boundaries of what assistive technologies can achieve are pushed, technological advancements are impacting lives by enabling individuals to communicate, learn and interact more freely with the world around them.
