Hi

Jamie can you resend document in word 2000 format

Are you expected to use LCD technology because this for a school project is extremely difficult especially if you have done no micro theory or programming and doesn’t sound quite right to me LCD Interfacing techniques etc is normally restricted to HNC, HND and Universities

Something doesent quite sound right here to me

This is undergraduate subjects that we are discussing here Id be happy to see your design but LCD technology and interfacing with commands etc nibble or byte orientated plus timing techniques This can take quite a considerable amount of time to get used too particularly with scrolling messages , You have to also understand write a considerable amount of topics in relation to the hardware this includes driver technology serial or parallel etc without getting to complicated for you

As a further thought regards this subject could you define what you mean by quadriplegic there are obviously different categories of analysis

this is important beacuse you need to know what part of thier body still functions and what they can and cant move or feel

A Complete no motor or sensory function is preserved in the sacral segments S4-S5.
B Incomplete sensory but not motor function is preserved below the neurological level and includes the sacral segments S4-S5.
C Incomplete Incomplete: motor function is preserved below the neurological level, and more than half of key muscles below the neurological level have a muscle grade less than 3.
D Incomplete Incomplete: motor function is preserved below the neurological level, and at least half of key muscles below the neurological level have a muscle grade of 3 or more.
E Normal motor and sensory function are normal.

Mark, I am also using an old version of Office, there is a freely available compatibility pack for the new formats like docx:

Hi Mark. Thanks for your time...
I am senior at the University of Mass Lowell.
I have completed a Microprocessor based systems course in school.

I have also included the file as a PDF.

Thanks again. any help will be appreciated!

Also I forgot to mention that the person can only move his head. To my understanding he also has an efficient cognitive ability.

Hello everyone,

I am doing a school project and i want to design a head switch for a quadriplegic person who can only move his head. I have provided a rough sketch of what I am planning to do; however, I have no idea (or any background really) of how to work with lcd screens. Any feedback on an online course/tutorial or reference on how to work with them will be appreciated..
Thanks!

You will have to excuse me Jamie my English possibly isn’t up to your standard can you explain what you mean by efficient cognitive ability Apologies for my lack of expertise in English at times

I will download the file and look now Thank you for putting this up in PDF format It makes life so much easier and less expensive I use a mobile phone to insert comments and answer questions here and it does get expensive when i have to download more often than not now this means you have to be connected with a connection 234 meg is approximately £40.00 If you are unemployed or have very little work plus updates etc It does become a real issue Its even more of an issue for people applying for work and even a bigger issue if they don’t answer emails sms or anything else I’m sure you as student are only to aware of this problem plus many people who are unemployed at present

Here is one quick page Ive found for you so far but what i could do with is what type of sensor you going to use I need a device name and datasheet for the Gyroscopic sensor

Here is the link in the meantime which adopts a different approach to sensing but never the less will help with ideas

No worries Mark. When I say his cognitive ability is efficient, I mean that he has NO disabilities in reading and understanding what people say to him. He simply cannot move his body or speak. he only moves his head.

As for the gyroscope and any other devices I have not chosen a specific one yet. I am mostly concerned in finding a course/tutorial (preferably free) that will guide me in working with graphic lcd interface.

Topic summary

The discussion centers on designing a head switch for a quadriplegic individual with only head movement capability, focusing on integrating an LCD screen for assistive technology. The project requires understanding LCD interfacing, which involves microprocessor programming, timing techniques, and driver technology for serial or parallel communication. The complexity of LCD interfacing is noted as typically covered in advanced technical courses (HNC, HND, university level). The quadriplegic condition is classified by motor and sensory function levels, emphasizing the need to tailor the design to the user's physical capabilities. The user seeks free online courses or tutorials on graphic LCD interfacing. Recommended resources include datasheets and tutorials from electronic-engineering.ch, ekenrooi.net, and harrington.force9.co.uk. Additional advice includes selecting appropriate sensors, such as gyroscopic sensors, with a request for specific device names and datasheets. A Microsoft Office compatibility pack is suggested for document format issues. The user confirms cognitive ability is intact, with only physical movement limited to the head.
