This week, we moved away from our Gantt Chart in the sense of parallelization; we 'went our seperate ways,' with Max focusing on the physical generator and Allen focusing on the analysis of gait motion.
Max created a block diagram to plan the design of the generator. This diagram includes the components that are included in the generator and helps to display a visual plan for the eventual designing and physical construction of the generator. His next step will be to translate these diagrams into 3D models. This will be done using Google SketchUp and the nodes isolated by the block diagrams to render designs of the different components that comprise the generator.
Allen went into more depth on the "Human Walking Analysis, Evacuation and Classification Based on Motion Capture System," which highlighted some key variables that some classmates had mentioned in their review of our presentation last week. Everyone has a unique walk, and it differs from gender and age. Balance is also a vital piece of walking. In terms of previous gait analysis research, most tend to focus on the sagittal (profile view) plane and ignore the traversal plane and frontal view. The researchers created a fourteen-linkage walking model, consisting of nineteen points, fourteen segments and twelve joints. This paper used motion capture technology to take down data, ranging from velocity to in-depty cycle data. After all, a walk is really just a series of periodic movements (for the knee). The data points to highest velocity occurring at the knee, but Allen will be looking to find other papers to compare.
Additionally, this week he began narrowing down choices for a video analysis tool. The idea is for him to record himself walking on a treadmill with some sort of market attached to his knee. The two video analysis programs are Kinivea and Sports Motion, which he'll work with on the same video and evaluate which gives the most comprehensive data.
