- | He has many years of experience working for the York University | + | The domain our group has selected is virtual reality and its application in education. Our concept is to create an education space created via virtual reality that is experienced through the use of a head-mounted display such as the Oculus Rift. We will be using the Accolade West & Goldfarb building of York University, as our educational spaces for the 3D environment. With this as our foundation, we will further develop our idea to determine an appropriate experience we can create given the knowledge of our research from the literature and through the early phases of development and prototyping. We are leaving part of our project open to different options since researchers have found, that new technologies such as virtual reality |

+ | virtual world known as “Second Life” had as a distant learning tool compared to a traditional | ||
+ | classroom experience [Hargis 2014]. Marlo Steed also published a similar study using an actual virtual reality environment to understand the possibilities and rationale that these systems had to offer [Steed 2014]. These studies will help us to examine how we can either push or innovate the benefits a virtual space has to offer or overcome limitations | ||
- | [[http:// | + | Second, we imagine that this virtual space could be utilized as a teaching tool for new or prospective students, representing a simulated gateway to the University. It would serve as a virtual tour for prospective students that want to learn more about the school’s facility or are unable to attend a guided tour at the University. It could also assist first-year students by familiarizing the environment to them or even provide a guided simulation to find the |
- | |{{: | + | locations of their classes. Another study by Dunleavy and Dede, studied the effectiveness of |
+ | augmented realities utilized with interactions of digital information embedded within physical | ||
+ | environments benefitted learning and enjoyment [Dede and Dunleavy 2013]. In our virtual tour, we | ||
+ | would have added interactive content straight into the virtual environment with respect to the | ||
+ | user’s position in the building such as details about labs, classrooms and other facilities. We | ||
+ | hope that by modeling ACW plus a few other buildings we will be able to do multiple things | ||
+ | such as tours, virtual classrooms, and even a scavenger hunt of sorts. | ||

- | ===== Description of Project ===== | + | - Dunleavy, Matt , and Dede, Chris. |
- | One of the main obstacles for long duration space flight is the debilitating effect of microgravity on astronauts; specifically muscle atrophy. We address this problem and mitigate this threat by challenging products on the market today and designing a device that optimizes the effects of a technique that has already been tested and trusted in the rehabilitation industry: Functional Electrical Stimulation (FES). | + | |
- | + | ||
- | Research has shown that performing Neuromuscular Electrical Stimulation (NMES) along with exercise, otherwise known as FES, has the potential to significantly reduce muscle atrophy. However, FES devices currently on the market rely on the patient to sync their movement according to the stimulation provided by the NMES device. Our product, will allow appropriate stimulation according to the movement of the patient, providing an ideal environment to use FES for muscle atrophy prevention, and not solely for rehabilitation. It can be used with a variety of exercising equipment from dumbbells to tension machines through a convenient wristband. This wristband contains an Inertial Measurement Unit (IMU) that, through a microprocessor, | + | |
- | + | ||
- | This gives the product direct applications in the health and wellness market on Earth, as well as the potential to solve one of the most impactful problems in space travel to date; especially in light of space tourism. | + | |

- | ===== Discussion ===== | + | |
- | === Novelty of the project === | + | |
- | While there are numerous products on the market for the specific purpose of performing FES for rehabilitation, | + | |
- | === Marketability of the project === | + | |
- | Muscle atrophy in space is a tremendous obstacle. | + | |
- | === Engineering design techniques === | + | |
- | We used the Engineering Design methods we learned in ENG1000. | + | |
- | We spent a significant amount of time reviewing existing applicable literature of this topic as research is a fundamental point. | + | |
- | During the conceptualization phase we came up with many versions and used an iterative process design that was continuously upgraded as we made sufficient progress. | + | |
- | We clarified the design requirements based on literature in what we needed to provide as a functional product. We emphasized from time to time the rudimentary design requirements so that these were always kept in mind throughout the entire project. | + | |
- | We finalized a final design for which we then started manufacturing components and implementing necessary technologies. | + | |
- | We finally made a prototype based on these subcomponents and assembled each of the components to launch prototype. | + | |
- | === Design complexity === | + | |
- | We kept our goal to choose a challenging topic while breaking down the problem into simpler components. As we learned in Engineering Design, the best solution to a problem is a simple one. We solved our key concepts using basic fundamental theory but with a unique application. | + | |
- | We had to build a device that would interact with a user and provide stimulation based on the user’s movement. The stimulation needs to be in the correct phase of the exercise motion. We build major components separately to avoid failures and created redundancy checks. | + | |
- | === Future development === | + | |
- | Next steps for this project are to create a more compact CAD model. As part of this, the NMES signal could potentially be generated internally by the microprocessor. A crucial next step would then be to conduct clinical trials and eventually get the product approved by the FDA. | + | |
- | Additionally, | + | |
- | The device could also be made compatible with inertial training devices such as the Bodyblade. This device in particular uses Isometric contractions, | + | |

- | During early stages of the project, we used flex sensors, that are relatively cheaper, to obtain exercise motion data. However the sensors were not suitable for rigorous exercises as it broke off during testing phase. The flex sensor also does not support multi-dimensional data. Thus, we decided to move on to a more expensive and reliable IMU sensor which is both durable and supports multi-dimensional data. | + | |
- | + | ||

- | + | ||
- | The preliminary circuit shown here supports the Inertial Measurement Unit (IMU) and user interface integrated with processing unit: Arduino Uno. | + | |
- | + | ||
- | {{: | + | |
- | + | ||
- | The Computer Aided Design (CAD) model was developed based on the real dimensions of the electronic components that we expected to use. The design discussion included many aspects, notably user safety, ergonomics, failure point, etc. | + | |
- | + | ||
- | {{: | + | |
- | + | ||
- | The CAD design shown in the previous figure was 3D printed with the aid of Graphics and Media at York, GaMaY. The first printed version was noticed to have low dimension tolerance and did not pass our quality assurance requirements. The actual components did not fit perfectly in the printed case. This was fixed in the second iteration and all the components had a pre-determined home. Later on, a few modification were made inside the case to adapt to the switch to more powerful processing unit: Arduino Mega ADK. | + | |
- | + | ||
- | {{: | + | |
- | + | ||
- | The final circuit shown here includes all the components that are part of the final product. This stage of the project gave us great opportunity to apply our knowledge from courses. | + | |
- | + | ||
- | {{: | + | |
- | + | ||
- | Our design makes use of a 6 degree-of-freedom IMU connected to an Arduino microcontroller to detect the user's motion throughout the exercise and trigger the NMES whenever a concentric isotonic contraction occurs. The IMU is built into a wristband for user comfort and can therefore be used with any existing exercise equipment, both in space and on Earth. | + | |
- | Once the correct contracting motion is detected, the Arduino sends a voltage of 5V to the base of a transistor in the NMES control circuit which turns on the electrical stimulation. Once again, when the contracting motion has finished, the Arduino removes the base voltage and the stimulation is stopped. | + | |
- | + | ||
- | {{: | + | |
- | + | ||
- | The NMES settings are preliminarily set to an 85 Hz bi-phasic square wave, with a 400 microsecond pulse width. The amplitude of the signal needs to be set manually for each user as this setting needs to be maximized while still remaining comfortable. The higher them amplitude, the more intense the stimulated contraction. | + | |
- | + | ||
- | {{: | + | |
- | + | ||
- | The LCD user interface not only provides the user with a way to interact with the product but also helps to optimize the workout and make the stimulation as effective as possible. Ideally it should operate under a 1/2 duty cycle, meaning 1 second of stimulation for every 2 seconds of active rest. Therefore, the user interface will display warnings when the current workout is deviating from this optimal tempo. | + | |

- | ===== Achieved Results ===== | + | |
- | + | ||
- | Satisfied objectives: | + | |
- | + | ||
- | * Parsed raw data from exercise motion | + | |
- | * Determined the appropriate stimulation technique | + | |
- | * Implemented stimulation technique that adapts to individual exercise routines | + | |
- | * Demonstrated visual evidence of motion tracking and stimulation activation | + | |

- | + | ||
- | {{: | + | |
- | + | ||
- | After filtering the raw values via custom made phase-peak filter, the data is now useful. The sensor data for a session involving bicep curl is shown next where the stimulation is applied during concentric contraction of the muscle. This phase of exercise is the part under the red line in the graph shown at the top. The beauty of the device is that the stimulation is only initiated when the muscle is in the right state of concentric contraction. | + | |
- | + | ||
- | In the graph provided, the exercise motion is filtered and any inadvertent movements do not trigger the muscle stimulation. Only precise concentric muscle contraction motion can trigger the muscle stimulation while any inadequate motion is filtered to comply with medical professional and existing literature. | + | |
