Summary

I am a proud tinkerer, inventor, nerd, student, and full-time software developer. From prosthetic arms, and educational learning platforms, to eye exams, it has been my goal to innovate for the future and create projects that will change the world. Learning is important and can be fun, which is why every year I put myself through circumstances that I would not normally be in, pushing the boundaries of my knowledge.

Research & Articles

WebODM allows users to generate point clouds, 3D models, and terrain from aerial images. With this Cesium ion integration, users can also fuse the data they’ve collected with other geospatial datasets, such as Cesium World Terrain, all placed in an accurate global context.

Add-on that makes it easier to publish and stream 3D models on the web via Cesium ion. Using the official Khronos glTF Blender exporter to convert the model to glTF before uploading to ion for tiling.

The future of navigation will be centralized around HD maps. While plenty of companies exist to provide this type of data, all are limited by paywalls and strict Terms-of-Service. A new map viewer, called “comma maps,” visualizes recorded paths driven, lane markings, and world features. Discussing the benefits of comma's approach to mapping, and the release of open source tool such as entium.

From games to complex traffic control systems, collision detection plays an important role in today’s modern computers. Currently there are two algorithms – Quad-Tree and Spatial Hashing – that are often used and at times it is based on personal preference. Spatial Hashing is a “bucket” based system where an objects relative area is increased and then inserted into surrounded buckets to be queried against. Quad-Trees are a recursive data structure that divide into quadrants as an object capacity is hit and a bounding box is identified for the selection of a quadrants.

An Intelligent Walker
Elderlyfexpand_more

An Intelligent Walker


Ask your Alexa to take you to a room in the house, and Elderlyf will automatically detect which room you're currently in, mapping out a path from your current room to your target room. With vibration disks strategically located underneath the hand rests, Elderlyf gives you haptic feedback to let you know when objects are in your way and in which direction you should turn. With an intelligent turning system, Elderlyf gently helps with turning corners and avoiding obstacles.

With a Jetson Nano and RealSense Cameras, front view obstacles are detected and a map of the possible routes are generated. SLAM localization was also achieved using those technologies. By using two servo motors that could independently apply a gentle brake to the wheels to aid users when turning and avoiding obstacles. Piezoelectric vibrating disks were also used to provide haptic feedback in which direction to turn and when obstacles are close.

Path Guidance for the Elderly


Utilizes open source hardware and API's to make the world more accessible for blind elderly people. Android Studio controls extrapolated 3D features using monocular vision. In addition, Android Studio provides a variety of packages and bluetooth solutions to alert the user of possible dangers in their path of travel. Arduino Uno and ESP 32 are used to enhance the connectivity of bluetooth to pass data from the user to the interface. The Arduino connects to two DC motors with home-made counter weights to generate vibrations that prevent the user from walking into unexpected objects.

Pairing Student Parents with Student Sitters


Ramily is a mobile app built on the mission of enriching the lives of student parents through reducing childcare concerns. Currently, an unmet need exists at West Chester University (WCU) for student parents, increasing the challenges of the already intense college process. Traditional daycare centers can cost on average $972 a month for toddlers and do not allow parents to pick and choose days of use. Using local West Chester babysitters allows for flexibility in being able to utilize the service only when needed. The app will function specifically for the West Chester University community as participants will be required to enroll with a WCU ID number.

Neurally Controlling A Prostetic Arm Through EEG's


Using the Emotive EPOC headset, a simple pattern recognition algorithm, and a Bluetooth interface a LEGO prosthetic arm can be controlled through thought. The headset takes in a raw EEG input then a program made in C using the emotive developer library correlates certain thought patterns to a calibrated action. The application then activates the Lego Mindstorms through a Bluetooth connection. Currently, the hand only has two groups of movable fingers and the thumb; however, in newer versions of the prosthetic more hydraulic arms could be added. The project was recognized by multiple fairs and has a broad range of applications.
