Module 7 Journal Entry

 

How many different sources provided corroborating evidence that supported the same facts? List the facts and sources.

I found several articles, reviews, and editorials about brain-computer interfaces.  I ended up pulling information from two main articles Shih et al., and Brumberg et al., plus a YouTube video (Mike Chi, 2015) because all the facts were pretty much the same.  The differences were what areas of focus their article expounded upon.  Shih et al.’s article was aimed for an audience in the medical field, while Brumberg et al. was an introduction to BCI systems. 

One difference was in how the different components of the BCI are labeled. Shih, Krusienski, and Wolpaw use the labels: signal acquisition, feature extraction, feature translation, and device output (Shih et al., 2012).  The article from NeurotechEdu, broke down BCIs into more components:  signal acquisition, preprocessing, feature extraction, classification, translation, and feedback device (Intro to Brain Computer Interface, n.d.).   Their article was where I pulled the information about where the signals were coming from, with the helpful brain diagram and the differentiation between the invasive vs. non-invasive signal sources.

Brumberg et al., focused on the facts surrounding the BCI components.  What kind of focus tool is used such as an eye gaze, stylus, or EEG reader. This article also provided facts and figures surrounding the selection rates of different BCI varieties (Brumberg et al., 2018).

Module 3 Progress Report

 With my focus leaning towards Augmentative and Alternative Communication (AAC) devices, I have collected roughly 6 articles that were related to my topic.  Of the six I was able to complete reading through 3 that were helpful and relevant to the subject area I am looking for.  An interesting tidbit I learned about Stephen Hawking this week was that with his AAC device using cheek muscles, he only produced one word per minute.  It dawned on me that the TV interviews I have seen on the news and documentaries were obviously staged and edited to eliminate the idea that it took a considerable amount of time for Hawking to answer in a complete sentence.  What I’m learning is that even though AAC devices to offer people an opportunity to share their thoughts and words, it takes a considerable amount of time and effort to do so when normal speech would have taken a fraction of that time. With that in mind, I'm leaning towards learning more about the challenges AAC devi...

Module 1 Journal Entry

 Journal Prompt: Consider possible topics for your research project in this course. What interests you about these topics and why do you think they would be a good fit for the course? Which research methodologies do you think will likely serve you well as you begin your research (experiments, literature review, surveys, etc.)? I am leaning towards Adaptive Technology devices that aid those with speech impairment. This area falls under the Augmentative and Alternative Communication (AAC), which means all the ways that someone communicates other than speech ( Augmentative and Alternative Communication (AAC) , n.d.) . I have a personal connection to this area that we briefly experienced years ago when my daughter was a toddler and was diagnosed with speech delay.   In the beginnings of her speech therapy, we used picture boards with Velcro attached icons as tools to help her communicate her thoughts and needs. This method is a very low-tech AAC to help with her speech and lan...
