Hi everyone,

My name is Fabio Andres and I study Industrial Design. I have chosen to develope a diving computer for my final project at school and have some questions for you!

I have created a short survey, which you are very welcome to answer (all the data will be used to gather information and explore areas, where the computers could be improved).

Please copy and paste this link in your browser to participate in the survey:

http://www.surveymonkey.com/s.asp?u=872811681205

You are also very welcome to post your ideas about how diving computers can be improved!

I appreciate your help and look forward to see, and discuss your answers!!

Thanks a lot!

Fabio.

HI there, please make a computer that has a small internal battery that can hold nitrogen info during a battery change. This is a very frustrating limitation of many dive computers. Thanks.

Excellent input so far. We will all be watching this forum closely to see what new ideas the end-user divers come up with.

somthing quite simple but I never saw it the back of the console be reflective to be doubled as a singlaing device. Like I said somthing silly but somthing that would be nice to have in a "pickle"

I don't know if this is even possible or not but if a computer can give u a read out about the current ur in ( speed direction ect..) would be kinda cool.

Never heard that one before. If it can read a current, how about putting a compass funtion into the brain and get it to measure direction and velicity and give the diver a corrected angle to swim at in order to correct for directional deviation. That would be cool!

Another good idea from Elec. Although, it seems to me as though we're starting to design the worlds coolest compass/navigation aid.
As far as comuters go, it would be cool to have a computer that could be linked to a PC or laptop that could then email/link to the home computer to download recent info while on a trip and also access archived log information from a remote site. This would be proof of experience without haveing to carry a paper logbook.
Or how about enabling the portable unit that the diver uses in the water with logbook program installation software that would enable the diver to use an external keyboard to add details to the dive profile such as location, site name, dive buddy name, notes of interest and a rating system for the site.

Hey guys! Thanks for your input so far. I will keep visiting the forum regularly!!

What do you actually think about a heart rate monitor? Could that help calculating the amount of nitrogen in the blood in a more precise way?..........

i like that idea brian0 maybe like a minni pc just for that instead of a big laptop carrying around , like these super cell phones now adays w the small keypad and 2x2 screen.
fabio the heart rate would be kool u can also check when ur buddy is panicking i like the heartrate too

Heart rate, if used might be helpful, but then you'd need to know more precise info on tissue density and the number of cubic feeet of air consumed at what depths for absorbtion rate. In that case, hydration would also be a useful factor.
The most commonly used method of gas absorbtion measurement is a doppler bubble counter. If this could be used after a dive, during the surface interval and before a repetitive dive, you'd have a great picture of what is going on in the the tissues. If this could be programmed to average over time, it would become intuitive for the conditions in real time.

Hi again!

I have heard very little about the Bubble Counter, do you know where I can find a bit more info about the way it works?.

Thanks!

The best resource that I know of for information on DCS data collection is Diver's Alert Network.
Take a look at the following link an go to "All Other Inquiries". These are the people that pioneered this technology.

All the things posted are great ideas and I don't down them a bit. However if you want more people to use computers...make them cheaper. I am not saying skim and make a nonfunctional device to kill people.I have 3 computers for 2 divers. I always carry a spare incase mine or my wifes dies. Has not happened yet but if it should the one with the failed puter could continue the dive and go on. I will go to add that my backups are bottom of the line stuff and I am going to buy another this season so we each have a backup, but they are expensive even for cheap ones. If you want to make me fork out some bucks for something though on the other hand. Give me a full decompression computer with a basic GPS screen on it. Nothing fancy full color stuff just the basic 1st gen GPS lat/long data and rough led picture of area. This would not be very usefull inland but when doing beach dives it would be sweet.

I have three dive computers. The best two, an Oceanic Pro Plus 2, and a Suunto Vytec, leave little to be desired while at depth, but there are a few items that would be pretty simple to do that I would like (I also happen to be a microprocessor controlled electronics design engineer.)

1. Logging. The Vytec and PP2 both have USB interfaces, and that's great, but it would be nice if they could remember more data. Most people don't log immediately before and after a dive, but rather much later after the trip. It would be nice if one could enter more log page info into the computer and have it remember it. Particularly air temp, dive type, and weight used.

It would be particularly cool if you could download a list of equipment from a PC via USB so you could check off which equipment you dove with and enter the lead weight you used and if it was OK. Weighting for different dive setups is one thing for which a log is great. Being able to download pick lists from a computer would be unique among dive computers as far as I know. As memory is so cheap now, and the USB interface is already a fact of life on higher end computers, it wouldn't take much more to make a lot more use of the feature. Such a feature could also be used to download a quick reference list displayable just before diving (last minute equip. check.), and while diving (like a wrist slate.)

Being able to record GPS coordinates before a dive, and compass directional info before/after & during would be fantastic. Don't need a GPS or compass built-in, just ability to enter and have it logged with the dive data. When you find something underwater, it's nice to remember how to get back to it.

The above would likely require a larger display like on the Pro Plus 2. It would be really cool if one could record a 10-30 second voice entry with each dive to enter reminders about whatever. That would download to the computer in an audio file identified with the date and dive number so it could be played back on the PC. Microphones and flash memory are cheap and durable.

2. A simple thing that would help me would be an adjustable minimum dive interval. When shallow diving with repeated surfacing for equipment change / stowage, the computers keep getting confused and logging multiple dives for what is really one extended foray. It would all be fixed if I could set the computer to "enter dive mode and stay there".

3. Another simple thing is to be able to review the last dive immediately on surfacing -- the Oceanic computers "lock out" the user for the pre-programmed 10 minute surface interval the computers use to decide a dive is "over".

How about being able to play Space Invaders while waiting at deco stops?

Ask and ye shall receive.
Sounds to as though MuckDiver and Fabio ought to collaborate on some of these ideas. I still think that, if a compass feature were integrated that recorded the headings and times, you could revisit an object/terrain feature fairly reliably. Looking forward to more ideas.

Like the idea of compass and recording your path, I also though having GPS may be good (for surface location). With the two combined, you could pin point your exact dive route!

It would also be awesome to integrate an interface to an electronic nav chart that would plot the approximate location underwater so that you could pull up on top of or right next to it on the surface. Depth readings might help unless in an area where tides are extreme.

Hi guys!

Last wednesday I presented a program describing the aspects of the computer I am going to work with:

- Use of "Bio-Feedback" to calculate times under water and decompressions based on the divers data (pulse, core temperature, age, body fat).

- Alarms: Better feedback from the computer.

- Display: How much info needs to be displayed? Possibility to customize ones display.

- Placement: Where should the computer be placed for easier access?

I will also try to work with some navigation aids, depending of the time avaliable. Safety is my priority by now.

I am going to start sketching and developing concepts in about two weeks. I will try to post them on the internet, so I can get your feedback.

I will keep you posted!!!

Thanks for your valuable help until now! and please, keep posting new ideas and some new/old technologies that can be applied!!!

Fabio.

Hi Guys,

I am building up some scenarios, which I would like to share with you. Is there any way I can upload them, so you can see them and tell me what you think?

Thanks,

Fabio.

Fabio... as for computer placement, how about on the wrist for the control tabs (as with the hoseless/air integrated systems), but with a heads-up display built into your mask using the new transparent ASICS, instead of the LCD version Oceanic just demonstrated?
I also like the idea of a GPS enabled "Trac-Bac" (ala Garmin), or a long-wave directional beacon to get you back to your boat if the drift was just a little too far.

The beacon sounds good. How about a two way system that can help the boat find the diver?
