Aside from helping deaf people communicate more easily, the SLC also teaches people to learn the ASL. Our product, a sign language coach (SLC), has two modes of operation: Teach and Learn. The SLC uses a glove to recognize the hand positions and outputs the ASL onto an LCD. The glove detects the positions of each finger by monitoring the bending of the flex sensor. Below is a summary of what we did and why: <o:p></o:p></span></P> <SPAN NAME="Intro" A> <P class=MsoNormal style="LINE-HEIGHT: 10.5pt; MARGIN-RIGHT: -6.85pt"><SPAN style="FONT-SIZE: 10.5pt; COLOR: #666699; FONT-FAMILY: Arial"><BR> 1) Build flex sensor circuit for each finger. Sew flex sensors and accelerometer onto glove to more accurately detect the bending and movement of thecomponents.</SPAN></P> <P class=MsoNormal style="LINE-HEIGHT: 10.5pt; MARGIN-RIGHT: -6.85pt"><SPAN style="FONT-SIZE: 10.5pt; COLOR: #666699; FONT-FAMILY: Arial"><BR> 2) Send sensor circuit output to MCU A/D converter to parse the finger positions. <o:p></o:p></SPAN></P> <P class=MsoNormal style="LINE-HEIGHT: 10.5pt; MARGIN-RIGHT: -6.85pt"><SPAN style="FONT-SIZE: 10.5pt; COLOR: #666699; FONT-FAMILY: Arial"><BR> 3) Implement Teach mode. In Teach mode, the user “teaches” the MCU ASL using hand gestures. To prevent data corruption, A/D converter output and the associated user specified alphabet are saved to eeprom, which can only be reset by reprogramming the chip. <o:p></o:p></SPAN></P> <P class=MsoNormal style="LINE-HEIGHT: 10.5pt; MARGIN-RIGHT: -6.85pt"><SPAN style="FONT-SIZE: 10.5pt; COLOR: #666699; FONT-FAMILY: Arial"><BR> 4) Implement LEARN mode. In Learn mode, the MCU randomly chooses a letter it has been taught and teaches it to the user. The user ”learns” by matching his hand positions to that which the MCU associated with the letter. Using the LCD, he can adjust his finger positions appropriately. The finger positions are matched to the appropriate ASL using an efficient matching algorithm. <o:p></o:p></SPAN><o:p></o:p></P> </SPAN> <H2 style="MARGIN-RIGHT: -6.85pt; mso-line-height-alt: 10.5pt"><SPAN NAME="Intro" A><img src="line.jpg" width="550" height="30"></SPAN></H2> <H2 style="MARGIN-RIGHT: -6.85pt; mso-line-height-alt: 10.5pt"><a name="HD" id="HD"><img src="image006.jpg" width="366" height="37"></a></H2> </SPAN> <p class=MsoNormal style='margin-right:-6.85pt'><b style='mso-bidi-font-weight: normal'><span style='font-size:18.0pt;font-family:Arial;color:#666699'>Rationale and Sources of Our Project Idea<o:p></o:p></span></b><b style='mso-bidi-font-weight: normal'><span style='font-size:10.5pt;font-family:Arial;color:#666699'><o:p></o:p></span></b></p> <p class=MsoNormal style='margin-right:-6.85pt'><span style='font-size:10.5pt; font-family:Arial;color:#666699'>There is currently an abundance of software in the market that is used to help teach people sign language.<span style='mso-spacerun:yes'></span>This software is very effective; however, it is very hard to know if you are doing a sign correctly and the same way every time.<span style='mso-spacerun:yes'></span>Current products in the market are not very interactive.<span style='mso-spacerun:yes'></span>In order to check yourself, you have to look at a chart of hand positions on the computer screen to check if you have signed a letter correctly.<span style='mso-spacerun:yes'></span>We wanted to make a project that would help people practice and learn sign language without having to look at a screen every time to check the sign for precision.<span style='mso-spacerun:yes'> </span><o:p></o:p></span><span style='font-size:10.5pt; font-family:Arial;color:#666699'><o:p></o:p></span></p> <p class=MsoNormal style='margin-right:-6.85pt'><span style='font-size:10.5pt; font-family:Arial;color:#666699'>For our project, we decided to move away from such software and use a glove in order to implement an interactive sign language teaching program.<span style='mso-spacerun:yes'></span>Our project is called the 揝ign Language Coach<span style='mso-spacerun:yes'> </span>We believe that, with the use of a glove, signs can be made with more accuracy and better consistency.<span style='mso-spacerun:yes'> </span>Having a glove also would enable students to practice sign language without having to be next to a computer.<span style='mso-spacerun:yes'> </span>Our project would be portable to all those who wanted to practice sign language.<o:p></o:p></span><span style='font-size:10.5pt; font-family:Arial;color:#666699'><o:p></o:p></span></p> <p class=MsoNormal style='margin-right:-6.85pt'><span style='font-size:10.5pt; font-family:Arial;color:#666699'>The concept of a sign language glove began with a high school student who won the Intel Competition in 2001.<span style='mso-spacerun:yes'></span>His idea spurred so much interest that sign language gloves are still being researched and developed for the purpose of translation.<span style='mso-spacerun:yes'></span>The sign language glove seems to be a very useful tool to aid in communication with the deaf.<span style='mso-spacerun:yes'></span>A professor at <st1:place w:st="on"><st1:PlaceName w:st="on">George</st1:PlaceName> <st1:PlaceName w:st="on">Washington</st1:PlaceName> <st1:PlaceType w:st="on">University</st1:PlaceType></st1:place> has received a grant from the government in order to research the capabilities of the glove.<span style='mso-spacerun:yes'></span>We believed that such a promising translator could also be an effective teacher to those who want to learn sign language.<o:p></o:p></span><span style='font-size:10.5pt; font-family:Arial;color:#666699'><o:p></o:p></span></p> <p class=MsoNormal style='margin-right:-6.85pt'><b style='mso-bidi-font-weight: normal'><span style='font-size:18.0pt;font-family:Arial;color:#666699'>Logical Structure<o:p></o:p></span></b><span style='font-size:10.5pt; font-family:Arial;color:#666699'><o:p></o:p></span></p> <p class=MsoNormal style='margin-right:-6.85pt'><span style='font-size:10.5pt; font-family:Arial;color:#666699'>Our glove is similar to the other gloves that have been researched and developed.<span style='mso-spacerun:yes'> </span>We have created a glove that learns different signs and saves these⌨️ 快捷键说明
