This week, I finished my CAD designing with Fusion 360. I installed an adjustable belt around the Rester 3000 so that it could be easier for users to wear them on their calf. Additionally, I attached the leather where users put their shin on top of the other leg, to give more comfortable experience.
This week I further worked on CAD model. I also made few changes compared to initial design, making few breathable holes on the product.
This week, our team mainly focused on the story line and statistical research of our final presentation. We also planned out our rendering concept of the CAD model, and the visual sources we would use for our presentation. I contributed on the personal usage story of our sleeping aid device “Insom-nomore” and conducting (rendering) CAD model.
For our final project, we once again switched our projects with team 3. We exchanged the concepts and started working on the concept “insomnia’. We initially chose to elaborate a temperature controllable sleeping mask with other provided concepts. However, while we were combining the concepts into a form of wearable device, we concluded the final product would be impractical and further disruptive for the people with sleeping conditions.I suggested my teammates to combine the concepts in the form of a non-wearable, independent product such as the lamp diffuser that one of the team 3 members presented.
We came up with a creation that has a diffuser spreading a pleasant aroma on one side, and a speaker emitting white noise on the other side. Above the speaker, it also has a blue light projector casting a calming blue light on the ceiling. The person dealing with insomnia can synchronize their breathing with the expanding and retracting light circle on the ceiling, guided by the blue light projector. It serves as a meditative practice to aid in falling asleep. The two parts of the product (Diffuser/ Speaker & Blue light projector) are detachable for users to clean or fill the water inside the diffuser while avoiding speaker and projector touching water. Essentially, we’ve consolidated tools like white noise, blue light, and aroma into one comprehensive idea.
The prototype below is a physical sample of our final product in advance of designing the CAD model. All three of our teammates participated in conducting the prototype while Kelly prepared the tools, Jasmin prepared the materials and I finalized a sample sketch of our changed prototype design.
During my sketching process, I drew inspiration from the “AI Pin” by Humane. Like the AI Pin, my sketch features a design meant to be attached near the chest area. It includes two cameras that facilitate a 3D detection system, with a GPS system to pinpoint the user’s location. This setup not only assists in navigation but also warns users of any obstacles in their path through audio device. On the right side of the device, there are two buttons: one for power and the other for Bluetooth connectivity. By holding down the Bluetooth button for three seconds, users can easily pair the device with their audio equipment. Finally, the device is attached to users by two magnet pins, providing stable and easy application.
This design is efficient due to its compact size, which makes it easy to wear and use without being obtrusive. This design effectively blends convenience and functionality, making it a practical choice for everyday use.
The concept of hidden interfaces closely aligns with Google’s “Little Signals” project. Both explore the application of technology into everyday environments in a way that is unobtrusive and harmoniously blended with the aesthetics of living spaces.
Google’s Little Signals project focuses on creating a series of non-screen-based notifications that communicate through movement, light, and sound. This approach provides information in a manner that is less demanding of our attention than the typical method of screen-based notifications. It’s a move towards a more gentle and integrated form of technology interaction, where the digital world can coexist more peacefully with our physical spaces.
Similarly, the hidden interfaces concept utilizes ambient computing, allowing digital displays and controls to appear on surfaces like wood, fabric, and mirrors only when needed. This idea furthers the goal of making technology less intrusive and more in tune with the user’s environment and lifestyle. Both concepts emphasize technology that is present when needed but invisible when not, reducing the constant visual presence of digital devices in our lives.
Reflecting on these innovations, I think that there has been a growing desire to move away from the traditional paradigm of always-visible, always-on screen signals. The future of technology in personal spaces seems to be leaning towards the importance of preserving the aesthetic and emotional quality of our environments.
My personal favorite among the Little Signals is the rhythm signal and motion of a tap. While contemporary technology poses efficient notification methods, like alarms and visual screens, I find the design and functionality of these two signals particularly interesting. Their approach is not only aesthetic but also embodies a minimalist ethos. The rhythm signal, with its subtle yet clear conveyance of information, and the tap motion, which mimics a gentle, tactile interaction, both represent a refined and understated way of communication. I think these signals exemplify a great balance between form and function, offering a refreshing alternative and more user friendly alert systems.
Rhythm – Rhythm generates ambient sounds. Quality of the melody conveys qualities of the information, like its importance, urgency, or tone. A way over the object, or simply turning it over, mutes it.
Tap – Tap makes use of surfaces to create the sounds that act as notifications. A stronger tap means more pressing news.
The concepts embodied in Little Signals offer possibilities for improving my project focused on tools for visual impairment. Applying these ideas could provide the way for less intrusive yet highly intuitive forms of communication. Instead of relying on audio signals, which can be time-consuming and potentially disruptive, especially when navigating familiar routes, we could integrate simple, physical signals. These concepts, inspired by the minimalist yet effective design of Little Signals, could provide essential information without overwhelming the user with repetitive audio instructions. This approach not only respects the user’s need for less auditory disturbance but also allows for a more convenient integration of our tool into their daily lives.
Audio Navigation Device
This week, our team started work on team 1’s disability theme, visual impairments. I thought the concept of an audio navigation device originated from a car’s navigation system, would specifically fit for this community. The device, worn by the user, utilizes advanced sensors to detect the surroundings. Furthermore, by synchronizing its real-time locating system with GPS or google street view system, it not only alerts the user to immediate obstacles but also provides guided navigation through audio instructions.
The proposed audio navigation device for individuals with visual impairments offers numerous benefits that significantly enhance their daily life and independence. This would provide real-time navigation assistance similar to a GPS system, allowing users to reach their destinations safely and efficiently. By using audio instructions to guide them, it helps in overcoming one of the major challenges faced by visually impaired people: navigating through unfamiliar or complex environments.
The device’s ability to detect and alert users to immediate obstacles in their path is also greatly increases their safety. This feature is particularly useful in busy urban areas or in situations where the environment is constantly changing, such as crowded streets or construction zones. It effectively reduces the risk of accidents and injuries, giving users confidence while moving around.
Moreover, the integration of the device with national GPS and potential smart city infrastructure ensures that the guidance provided is accurate and comprehensive. This integration not only aids in navigation but also keeps the user informed and updated about their surroundings, like notifying them of nearby facilities, public transport options, or changes in the urban landscape.
This week, our group had further discussions about the disability experience we aim to design for our “future selves challenge”, about the specific disability concerning hand tremor.
I contributed to the team by collecting materials needed for prototype, and providing research informations below regarding hand tremors:
The condition characterized by involuntary shaking or trembling of the hands (and sometimes other parts of the body) is commonly referred to as a “tremor.” There are several types of tremors, and they can be associated with different underlying conditions or causes:
The symptoms
Essential Tremor:
– Involuntary, rhythmic shaking of the hands and arms, especially while performing actions like eating or writing.
– Tremor may also affect the head, voice, or legs.
– May worsen with stress, fatigue, or consumption of caffeine.
– Typically does not occur at rest.
Parkinson’s Disease Tremor (Resting Tremor):
– Involuntary shaking that usually starts in one hand or finger when it is at rest.
– May also affect the chin, lips, legs, and other parts of the body as the disease progresses.
– Shaking usually decreases when using the affected limb.
– Other symptoms can include slow movement , muscle stiffness, and postural instability.
Intention Tremor:
– Trembling increases as the person tries to reach for an object or perform a task.
– May be associated with coordination issues and difficulty with fine motor tasks.
– Can be a symptom of multiple sclerosis, cerebellar stroke, or other conditions affecting the cerebellum.
Physiologic Tremor:
– Mild, usually imperceptible trembling of the hands or fingers.
– May be exacerbated by stress, caffeine, certain medications, or fatigue.
Our research involves various symptoms of hand tremors. We’ve chosen to highlight symptoms such as random tremors, stiff/ limited movement of joints, and overall numbness and weakness of the hands.
We conducted a prototype of oily gloves with several restraints around the finger joints for limited range/grip, smartwatch alarm for random shakings, and tight rubber/band for numbness. These conditions will enable participants to experience tremor disability.
For our project, participants will be tasked with playing Jenga, typing, and threading. Additionally, we plan to record the time it takes for participants to complete these tasks both before and after simulating the symptoms, to show the potential increase in duration for these activities under the influence of such symptoms.
Just like video of HYPER REALITY, Augmented Reality (AR) glasses may soon become as indispensable as many tools originally invented for people with disabilities but now used by everyone. These tools, like the text-to-speech technology and predictive text input, have originated from their initial purpose to offer convenience and enhanced functionality for a broader user base. AR glasses have the potential to significantly change how we interact with the world, much like how tools designed for individuals with disabilities often find broader applications.
As we could read from “turn on the lights” reading, the proliferation of smartphones and other screen-based technologies has led to a paradoxical state. While we are more connected than ever before to people and information across the globe, these devices often demand our isolated attention, pulling us away from direct engagement with the physical world and the people around us.
Potential Positive Impacts
Integrated Interaction: Unlike smartphones, which require users to look down at a screen, AR glasses could allow for information to be displayed within the user’s field of vision, allowing for more natural interaction with the environment and people.
Hands-Free Use: Smartphones require the use of hands to operate, which can be a barrier in many situations. AR glasses would allow users to engage with digital content hands-free, potentially reducing the need to “step away” from real-world interactions to use a device.
Social Presence: By overlaying digital interactions onto the real world, AR glasses could enable people to be more physically and socially present. For instance, while having a video call, instead of looking at a screen, the person you’re talking to could be projected into the space next to you.
Potential Negative Impacts
Constant Connectivity: While smartphones can be put away, AR glasses can potentially lead to an always-on state where interruptions and digital information are persistent, potentially occurring issues like digital distraction and information overload.
Social Disconnection: Even though AR allows for a more integrated experience, the constant flow of information could still create a barrier between individuals. People might be physically present but mentally engaged in a digital overlay, leading to a new form of social isolation.
Dependency and Overreliance: With the convenience of AR, there is a risk of overreliance on digital assistance for basic tasks, potentially atrophying our natural abilities to remember, navigate, and even recognize faces without technological aid.
AR glasses could result in a more integrated technological future, but they also carry the potential harms.
It’s essential to address potential issues that could arise, such as digital distraction, disconnection of personal interaction. AR glasses have the potential to become the next widely adopted technology that, while initially assisting individuals with disabilities, offers extensive benefits for the general population. They are likely to change how we interact with our environment, offering a more intuitive and integrated digital experience. Like the assistive tools before them, AR glasses could blur the lines between assistive technology and mainstream convenience.
