Project description: Falls are a major health risk for older adults and patients, as they diminish the quality of life and are a major cause of pain, disability, loss of independence, and premature death. Older adults tend to use different types of glasses for different activities (e.g., near vision glasses for reading, distance glasses for walking). Forgetting to change near vision glasses into distance glasses when switching to a different activity, or vice-versa, is a major cause of falls. We plan to address this problem by detecting when a user switches to a new activity and alerting them to change glasses when a relevant activity transition takes place. We plan to use inertial sensors (accelerometers and gyroscopes) to capture user movement data, to determine what activities users are engaged in, and to alert them when switching glasses is necessary.

Project goals:

• Develop a head-mounted inertial measurement unit (IMU) based system for detecting Activities of Daily Living (ADL)
• Recognize at least 10 ADLs through multiple supervised and unsupervised algorithms
• Detect relevant activity transitions and alert user
• Receive feedback and improve the system

Project description: We have created a dog model in our motion capture software. We attach reflective markers to joint landmarks on a dog (Dollie) and have her walk through our calibrated space where her motion is captured by 9 infrared cameras. Our motion capture software allows us to create an avatar of Dollie so we can see all of the displacements and velocities of the markers and the angles of Dollie’s joints.

Project goals:

• To learn enough about dog gait to allow us to make a prosthetic device to assist a dog who is missing a leg.

Project description: The development of a mask that is designed which helps stop the spread of Covid-19. This design is intended to help the spread of Covid-19 by adding an extra layer of protection from germs while one is drinking. This mask is intended to be worn with the hole closed until one is drinking. The hole can then be opened while drinking is occurring, creating only a small opening to reduce the amount of germs passing through during the drinking process.

Project goals:

• To ensure the mask performs effectively when being used during common activities
• To minimize the amount of germs passing through during the drinking process
• To provide ease of use and comfort for the user

Project description: We are adapting the software and AI technology within smart speakers, like google home, so that they may be more accessible to people who use sign language, especially the Deaf Community. The product will most likely be a software extension that can use sign language recognition in a similar way that it already uses voice recognition, and output text to the screen while it executes commands. We are dedicated to being respectful of the Deaf community, and our business and marketing plan will be considering their culture, frustrations, and how they receive information about new products.

Project goals:

• Develop a software extension that can utilize sign language input for smart speakers through image recognition.
• Effective communication between smart speakers and members Deaf community.
• Change smart speaker output to on-screen text.

Project description: We are designing a product that will automatically dispense the correct prescription at the right time for the elderly and patients with dementia. The idea is that when the patient wakes up in the morning, the first thing they will do is go to the restroom, walk up to the mirror and the mirror will tell them which pills that they will be taking and at what time they will be dispensed.

Project goals:

• Automate the dispensing of pills to remove the need of them being given out by a caretaker
• Alerting the patient, caretakers, and physicians when a prescription is running low and when a new prescription needs to be picked up by
• Sleek design, should look normal in the bathroom setting

Project description: The goal of this project is to create a system of one or more cameras, in conjunction with AI and mobile computing, to help prevent injury during home workouts. We plan to have a mobile application working on Android to begin with, but can be expanded to iPhone, which can be setup to record an exercise. This recording will calculate angles of joints and movement to determine if the user’s exercise is following good form. If not, a notification will be given to alert the user that a potential injury could occur due to their exercise form.

Project goals:

• Reduce injuries due to bad form
• Improve accessibility of personal training
• Help people get fit

Nonlinear dynamics is exhibited by electro-mechanical-structural systems under certain operating conditions. This nonlinear phenomenon, for harmonically excited systems, may include emergence of sub- harmonic and/or super harmonic response. Linear analysis tools inherently fail to capture the nonlinear phenomena in the design stage and hence are of little value when utilized for prediction of nonlinear dynamics of interest and the associated parametric analysis for trade-off studies. Many sources of nonlinearities are inherent in the ultrasonic cutting tool which include geometric, material, piezoelectric nonlinearities. This research is to investigate a design of controller for operating these cutting tools.

Through the use of a non-human analogue, human balance may be studied without the risks and costs associated with the use of human test subjects.One of the main goals of this robot would be to capture the differences in its center of pressure (CoP) by measuring its fluctuations about its upright equilibrium. Because of this, our device would act as an inverted pendulum in order to measure the change in stability. In addition, the robot would contain a ball and socket to imitate a human’s knee and hip joints so that tests and measurements may be more accurate. The research that may be done using this robot to will allow a better understanding of mechanisms in stability. This device would be able to benefit people with balance disorders and elderly people because of its potential to successfully contribute to postural stability research. Furthering research to better understand an upright stance will allow people who suffer from neuromuscular disorders (such as Parkinson’s disease and multiple sclerosis) as well as the effects of old age to prevent injuries, reduce medical costs, and aid their overall well-being.

This research serves to develop a virtual application which lets victims undergo immersive virtual therapy sessions under the choice of supervision from AI, in-person therapists, or online therapists. To address the issues of accessibility, sufferers of PTSD will now be able to have their own therapy stations in their own homes or nearest medical center. Another goal is to cut down the cost of treatment by consolidating many therapy services into one building in which therapists can connect to requested therapy sessions online and manage the supervision and walkthrough remotely. This will still allow therapists to physically travel to therapy site locations, personal homes, or veteran affairs centers but now permits victims to acquire the needed treatment discreetly without the previously mentioned worries. By incorporating machine-learning based AI in conjunction with heart-rate responsive scripts (in future versions) to control & supervise sessions, it also provides service to those far from therapy services or those without internet as they can now use a sort of ‘auto-mode’. This application is not only more effective, but more accessible. By cutting down costs, increasing accessibility, and increasing effectiveness this will increase the amount of sufferers to finally seek the treatment they greatly need.

Recent mathematical models of human posture have been explored to better understand the space of control parameters that result in stable upright balance. These models have demonstrated that there are two types of instabilities – a leaning instability and an instability leading to excessive oscillation. While these models provide insight into the stability of upright bipedal stance, they are not sufficient for individuals that require the aid of assistive technologies, such as a passive-cane or a walker. Without a valid model one is unable to understand the control parameters required for maintain upright posture or if similar instabilities even exist when assistive technologies are used. Therefore, in this study, we developed a mathematical model of human posture while using a passive-cane to examine the nonlinear dynamics of stance. This study will enable design of a better cane for use in balance and gait.
