If the current superb looking design doesn't work out,

Just had the following message from EduPro, in the Netherlands:



--- Quote ---I am not sure that the Funkey [track-ball] works on a Playstation 2, I think it does not, because on the page I mention the port it works on, and that is the PS/2-port and this one has nothing to do with the PS2..... Sorry, my mistake!, there is however a new device that is meant for children with physical dysabilities, that works with the Playstation 2. This week I got a mail about this one. I will look it up as soon as I am in my office and get back to you, o.k?

I'll keep you all posted...

Here is a basic list of items SeaMonkey should discuss with Sean regarding the CP from my perspective.  If anyone has any further suggestions, please quote this post and add your input.  Any other additions, please quote the last (most current) list and add more suggestions.  This way Sea Monkey can print the last applicable post for his visit with Sean.

-----------------------------------------------------------------------

Questions -

- Double check overall dimensions of the cp chassis. Currently it is approx. 20" long x 11" wide x 5" high (that is from the bottom of the beanbag to the wrist rests).

- Determine optimum height from bottom of the beanbag to the top of the cp and to the top of the wrist rests.

- Determine correct angle(s) at which Sean's arms will rest on the cp. Drawings to date show them straight on, my suspicion is that they will be angles inward.  Tracing his arms on the cp in the applicable positions would be helpful.

- Have Sean pretend to move sticks, contact buttons, etc. in order to determine if his range of movement will allow him to operate the cp as pictured.

- Ask Sean about how he would prefer the cp to mount meaning should we use the beanbag and have the cp sit on his lap or should we make "hangers" on the sides so it can rest on his wheelchair.

- If hangers are desired, take applicable measurments.

- Discuss the weight of the cp.  What are the implications of X amount of weight resting on his lap if the beanbag approach is desired?

- Survey how his PS2 is setup.  How does he play now?  How does he load disks?  How might he use and then stow the cp?  With assistance?  If there is anything we can do to make that easier let me know.

- I am unsure if Sean knows about MAME.  He mentioned that his all-time fav game is Dig-Dug.  There is a PS1 namco disk that has dig-dug but also school him on MAME and see if he would rather go in that direction.  Who knows the pelican controller may satisfy him for the PS2 usage, then we might build him a MAME cp.

- If possible, pictures of Sean's hands may be helpful, even better if he is holding a joystick so I can get an idea of how his hands might rest on the cp.  Would he have his hands on top of the joysticks or on the side with his hand resting on the cp?

I've been trying for some time to make an accessible universal controller. Finding out about this forum is really exciting. I'm keen to help if I can, and I'm also keen to find help too - ideally through finding a solution for Sean.

My current work so far on a PS2 / universal accessible controller:



The X-arcade controller has switchable analogue modes. The digital joystick can act as the D-pad, or the left analogue stick or the right analogue stick (on the press of two different buttons). It also has the option for full push - or half push. A good compromise I thought.

However - this unit has suffered from 'ghosting'. The controller operates by itself randomly when I connect external switches. I and others are looking to solve this problem, but so far no luck.

My X-arcade D.I.Y. page is here: www.oneswitch.org.uk/4/DIY/x-arcade.htm

I've also worked on a Dual-Shock 3rd party controller (easier to adapt) and a 4gamers arcade stick. The 4-gamers stick has a 3-way switch which assigns the D-pad / left stick / right stick to the digital joystick. The 4gamers stick is quite easily available on eBay.co.uk:



These are both fairly straight forward to adapt, but if you press left and right together or up and down together, the controller would short out, resetting the Playstation. A real problem for disabled gamers using switches, and one I'm still looking for a solution to. However - this might not be a problem for Sean if he uses three joysticks.

Best of luck all.

Arcadiac:
WOW great work all.  It seems as if we all just need to take a deep breath and wait for some input from Sean and seamonkey.  Hopefully the package I sent will arrive in time to take to Sean, I'm excited to see where this goes, the implications for adapting a controller for my son is very encouraging.
Keep up the good work all and as always Thank You!
ARCADIAC!
