Logbook

Our team has reviewed all the project proposals and agreed to work on “Smart Health and well-being“. We brainstormed various concepts and set on our project – Healing Spaces. During our classes we developed our business concept and have identified our first idea of the target group (long-stay patients, especially children) as well as our core initial problem, which are the sterile, anxiety-inducing hospital environments. To make that happen the methods and materials from Marketing course were used and we created our value proposition chart.

We started looking for the already existing solutions, but we need to do more research on all possible solutions to make a more pleasant room/space, and improve the well being of people.

We want to focus on children that stay for a long time at the hospital. We searched about other solutions that could improve their well being.

We want to combine several sensory experiences into one device (or several devices if needed): visual projection, music/sounds, and potentially calming smells. The goal is that children can feel almost like they are at home, or to feel like they are outside the hospital, helping them mentally escape the clinical environment and reduce their anxiety.

We tried to develop the user journey map of our product (during the Design thinking workshop), to think about how our product could be used by the children.

We started to think about the ethical and safety contraints of our device: ensuring the projections do not trigger photosensitive epilepsy and figuring out how the device will work in shared rooms without distrubing other patients.

Another brainstorming about how can we make our idea stand out? We considered smart glasses: they could be connected to a device placed in the parents' house so that the child could call them and see them appear in front of them, as if the child was at home. This is different from a computer because the child could simply move their head to see the inside of their house, the pets, etc. Also, it could be a solution if two children are in the same room.

Some problems: the glasses are screens pretty close to the child's eyes: so the use of glasses must be supervised to avoid damage to children's eyes throughout their stay.

First try about the Black box diagram here : https://www.eps2026-wiki6.dee.isep.ipp.pt/doku.php?id=report#hardware1

And first creating the storytelling of our product during Design thinking workshop.

This week we further developed and partially redefined our original idea around the “cocoon” or a multi-sensory projector. We compared various approaches, including smart glasses, virtual reality applications and our Cocoon approach, to identify the most sensible and effective solution.

Another step was to revise our black box diagram. We have adapted this to show how our system works more clearly and to better structure the individual inputs and outputs. In addition, we looked more closely at the topic of fear and discomfort in waiting areas, for example in dental practices. The aim of this research was to better understand which factors trigger stress and anxiety and how these can be specifically counteracted. Building on our basic idea of ​​a multisensory device, we have also started to create an initial bill of materials (BOM). In the area of ​​sensory appeal, we particularly focus on the elements of sound and Scent busy:

• Sound: Studies show that music therapy can relieve pain, reduce anxiety, and improve overall well-being during treatments.
• Scent: The use of aromatherapy, especially with the scent of lavender, has been proven to reduce anxiety and pain - especially in children before treatment.

These findings form an important basis for the further development of ours multisensory concept.

This week we worked intensively on the design of our “Cocoon” project. We researched and compared various sensors and electronic components and finally made a selection that we would like to use for further implementation.

Another focus was on designing our logo. This shows a cocoon from which a butterfly flies out, symbolizing development and transformation. When choosing colors, we consciously chose blue, green and purple:

• Blue has a calming, relaxing effect
• Green has a balancing timing
• Purple also has a calming effect and is associated with what we use Lavender scent

We also designed a flyer. After joint coordination, we made adjustments to the background color and font size to improve readability and visual impact. Finally, we created a materials list that serves as the basis for the next steps in our project.

This working week focused on finalizing our presentation documents and technically refining the design. A key milestone was the completion of our product flyer. In this, the diverse functions surrounding the “Cocoon” were clearly arranged and supplemented by a new view that visualizes the option for wheelchair use. At the same time, we have refined the SWOT analysis in the area of ​​“opportunities” in order to highlight the market potential even more clearly.

Technical optimizations and accessibility In the area of ​​construction, decisive adjustments were made to increase the flexibility of the furniture:

• The chair's swivel castors are now height-adjustable, which enables optimal adaptation to different surfaces and user needs.
• Thanks to a newly integrated ramp, the standard chair can easily be replaced by a wheelchair if necessary.
• For additional ergonomic comfort, the chair has been supplemented with a back support for the feet.

Material vision and hygienic standards In order to make our vision tangible, detailed material sketches were created. For the external structure, we are planning a combination of copper arches and PVC, with an integrated air gap providing effective sound insulation from the outside world. In the interior, we rely on high-quality textiles from the “Health Care” collection, which were specially developed for well-being:

• Hygiene through innovation: The fibers used are equipped with firmly integrated silver ions. These inhibit the growth of microorganisms and bacteria, which not only improves hygiene but also reduces odor formation. Since the ions are firmly anchored in the material, they only work there and do not enter the environment. Care and safety: The textiles are flame-retardant, washable up to 60 °C and meet the highest standards such as the OEKO-TEX® standard and certified antimicrobial effectiveness according to ASTM tests.
• Healing-promoting design: In collaboration with experts, a color concept of positive, natural colors was chosen that can actively support the user's healing process.

Through this combination of technical sophistication and high-quality choice of materials, we have succeeded in creating a harmonious and functional overall image of the “Cocoon”.

In the last working week, our team (Team 6, EPS 2026) reached significant milestones in the development of the “Healing Cocoon” to realize the vision of transforming moments of fear in children's waiting rooms into positive experiences.

Conception and marketing strategy A key focus was on the strategic orientation. We finalized the SWOT analysis and particularly highlighted the strengths of our product - such as complete accessibility and high hygiene standards. Our product flyer was completed to clearly present core aspects such as multisensory relaxation (scents, sounds and 180° projections). In addition, the market positioning as a high-quality solution for pediatric facilities was sharpened.

Technical design and accessibility Significant advances have been made in the area of ​​construction:

• The structural drawings and technical schematics for the system are now fully developed.
• Particular attention was paid to wheelchair accessibility in order to guarantee inclusive use.
• The choice of materials was made with sustainability in mind. We rely on durable and recyclable materials such as aluminum and brass and prefer to work with local suppliers.

Sensor technology and multisensory experience In order to achieve the goal of reducing anxiety, we have specified the technical equipment of the cabin:

• The integration of a lavender scent system and music therapy elements was technically planned to create a calming atmosphere.
• The visual concept uses a palette of blue, green and purple to promote relaxation and balance.
• We have completed the selection of electronic components, such as the ESP32 DevKit, as well as sensors for humidity, temperature and CO2, to ensure a safe and smart environment.

Digital development: website and dashboard In addition to the physical components, we worked intensively on the website for the “Healing Cocoon”. The user interface for the “Smart System” was developed, which includes a login page for clinics and a clear dashboard (user page). This dashboard allows medical staff to easily manage sessions, check accessibility status, and select different relaxation environments (such as “Ocean” or “Forest”) for the children.

By combining technical precision, well-thought-out marketing and intuitive digital control, the project took a big step towards prototyping this week.

1. Presentation
2. Modus operandi
3. Project proposals
4. Electronic logbook (Wiki)

Supervisors presented the different topics of the project to us, along with the wiki we will use to keep track of everything related to the project. Then we stayed behind to choose and discard the topics that each of us considered most interesting. Finally, we brainstormed more specific ideas for the different topics.

1. Review of the Brainstorming
2. Project Selection
3. Communication with supervisors

In this second meeting, we focused on giving shape to the initial ideas for each topic. After doing this, we voted on the three topics that each person found most interesting, along with the ideas mentioned. Finally, we sent an email with the ranking of the topics.

1. Presentation of the idea powerpoint
2. Feedback from the supervisors.
3. Next steps.

We have presented our first idea, which is to try to improve hospitals by allowing patients to draw on a device and project it onto the walls, or to project directly a picture from a data base, to improve their stay and reduce patient stress and anxiety, improve emotional well-being and support mental recovery.

The feedback we have received on our idea is to make it more specific, as there are several points that still need to be defined. For example, we need to consider whether we also want to add music or other senses, what we are going to do with people who are unable to draw, how many projectors we are going to have, and what happens in rooms with many people.

For the next steps, we need to research competitors, benchmarking, and existing solutions. We also need to consider how to make it as sustainable, ethical, and inclusive as possible. Finally, we need to think about all the components we will need and use that to create the ‘black box diagram’.

1. Our idea and other possibilities.
2. Feedback from the supervisors.
3. Next steps.

We talked about our idea and new ideas and possibilities.

We showed our first draft of blackbox, the feedbacks we had: is the app from the user interface? Wi-fi? Bluetooth? All devices need to be powered (projector/scent sprayer/speaker). We need to put some sensors (to measure the brightness level, noise level, moisture level???).

Cristina talked about something we started to think about: we need to be sure that the kids will not be impacted/damaged by the light/sounds (for example the photosensitive children or other psychologic pathologies). Also, sharing the devices between children with diseases could be problematic.

We may try to find and focus on another type of public or solutions: children in stressful situtation (dentist, psychologist…) ; a kind of cocoon where the child can go inside, see, smell, and listen to what he wants without bothering the other in the shared space.

1. Feedback on renewed blackbox diagram
2. Feedback on updated user stories
3. Present our refined concept: the HealingSpaces Cocoon

We presented our refined concept, the HealingSpaces Cocoon, and shared our comparison of different technologies (VR, smart glasses) to explain why the cocoon is the best solution for shared waiting rooms. We also showed our BOM, and the concept visuals of the prototype. For the black box diagram, we received technical feedback: Wi-Fi is a medium, not a component, so it shouldn't be drawn as a block. Also, air, area and sound should not be listed as an output of the system, and we need to clearly show that actuators are part of the system. Regarding the physical design, the supervisors pointed out disabled children on the wheelchairs, and how to make sure our product is inclusive. We also need to analyze the specific materials used inside the cocoon (their structure and properties) and maybe consider adding a contact sensor to trigger the system, plus voice-to-text functionality for our interface to make it more accessible. For the future, we discussed that our actual physical prototype needs to be a scaled-down version of our overall vision. We also need to ensure our project includes functional, non-functional (technical), and usability test. Lastly, we need to work on updating our report weekly, so that our progress is clearly visible for the coordinators.

• Finishing the design of the cocoon
• Selecting sensors and electronics
• Making a logo
• Creating a flyer
• Materials

Feedback we received for chair design: Some of our designs don't match: sometimes a leg rest is included with the chair, and sometimes it isn't. Also, a solution to easily remove the armchair (and thus take it out of the cocoon to allow entry for a wheelchair) would be to include small wheels on the chair's base that could be attached once inside the cocoon and unlocked to allow movement. So we need to work on that.

Also, feedbacks about the materials: a thin layer of air can be used between the walls of the cocoon to “naturally” insulate the sound. Copper and copper brass could be of interest, particularly from a health and antibacterial perspective. Further research is needed to determine their compatibility with our project.

• Detailed Schematics Review
• SWOT
• Change of name because copyright
• Start of Life Cycle Analysis
• Interim Report Questions

/!\ in the swot: in strengths: “Inclusive and wheelchair access” (and not “accessible”)

Flyer: we just need to add the last design with the chair and small wheels

Speaker: how it will work? microcontroller? Wi-Fi? Blueutooth? MP3 shifts(?)

/!\ schematics need to be compatible with the new design: do we need to put the projector inside the schematics?? vibration/motion motor?

/!\ Design: scent diffuser put on the top OR bottom of the cocoon? Because naturally the smell might be able to move from bottom to the top?

ALSO: we need to detach the tablet from the big chair because how the child in wheelchair will control it?

Materials: antimicrobial textile: curtain of hospital ⇒ silver ions, Creation Baumann

The report is still very incomplete (introduction, products already existing that we need to compare with our idea, the researches done on this subject, the choice we did)
