The Lusee solution implemented for Visana enhances the interaction between insurance advisors and clients. The process begins with the advisors capturing key data in a digital dossier during initial consultations. This dossier serves as the foundation for demonstrating relevant subject areas and insurance products.

The Lusee device which resembles a classic ceiling lamp, opens up an immersive space on the table where the customer and advisor engage, introducing a range of functions:

Lusee automatically identifies and stores handwritten notes, enabling playback during consultations.

Advisors can seamlessly reveal or conceal additional dossier information by touch, ensuring information availability without disrupting the natural flow of conversation.

Our engagement with Lusee started with our CTO conducting a thorough analysis of Lusee's framework and technology, and developing a proof of concept to determine the most effective implementation strategy.

The complexities of the user flow, involving token interactions, required a solid solution for event handling. When a user places a token on the table and interacts with the projected screen, specific states must be triggered. Introducing another token requires the system to react by overlaying a new page. Also, we needed to handle scenarios where a user removes a token or introduces written content on a piece of paper. These actions demanded meticulous event handling to ensure the application responded appropriately, navigating through diverse states and preserving the fluidity of the user experience.

Our collaboration with Lusee's engineering team helped us define the solution for event handling, laying the groundwork for a seamless and engaging user experience.

Following the proof of concept stage, we created a web app that seamlessly integrated with Lusee's backend. This phase involved a team of two software developers and a project manager from Modeso.

During the web app development process, our tech team collaborated closely with Lusee's implementation team, which was focused on building the algorithm for connecting the Kinect motion sensor with the Electron framework. The backend, linked to the motion sensor and projector, interprets signals and translates them into specific actions. For instance, placing a token on the table triggers the sensor, leading to the projection of a designated page.

After this project was finished, we continued working with Lusee on the development of a refined version of their application called Lusee Starlight. In this version, Lusee's team modified the backend implementation, allowing us to focus solely on developing the front end of the app.

Lusee operates on a robust foundation, employing Electron for the backend – a versatile framework designed to build cross-platform desktop apps with JavaScript, HTML, and CSS.

On the front end, we initially used Angular, but Lusee’s Electron implementation faced challenges, particularly in terms of responsiveness and the effectiveness of features like handwriting recognition.

Recognizing these limitations, Lusee’s tech team did a major refinement of their framework in Lusee Starlight, the subsequent version of the application. This refinement allowed us to use React to fully integrate with their new solution. While the functional aspects such as page content and user flows remained the same compared to the previous version, the migration to React significantly improved performance and responsiveness, providing a more efficient platform for Lusee’s interactive capabilities.

Testing posed a major challenge in the development process as we couldn’t solely depend on an emulator to assess the application’s interaction with the hardware.

The emulator, while serving its purpose in configuring starting positions and simulating key scenarios, fell short in replicating critical user actions such as touching the table, writing with a special Lusee pen, or accidental clicking. Also, since the emulator was built for Windows and our team worked on Linux, it didn’t provide a reliable solution for our development efforts.

To get a better understanding of the device’s behavior, we performed on-site testing sessions. Our technical project manager visited the customer’s location in Zurich to conduct testing with the actual hardware, identify bugs, and communicate them to the development team. Because our tech teams are in Egypt, where the bulk of development occurred, we used Team Viewer to facilitate remote access and find a compromise between physical presence and efficiency.

Our on-site testing sessions ensured prompt fixes and the deployment of updated versions, ultimately closing the gaps in the testing phase.
