Hi There, I was just wondering if either of the three loadstoners might consider answering a few questions posed by this list on the product? The report by Ronan was excellent, but wouldn't it be good to have a little follow-up? I wonder how you would listen taking note of your immediate surroundings; I suppose that you wouldn't use a full headset but possibly an earpiece. Looking forward to further info. All the best, Tony Sweeney. ----- Original Message ----- From: "Sandberg, Robert" <robert.sandberg@xxxxxxx> To: <vicsireland@xxxxxxxxxxxxx> Sent: Monday, January 22, 2007 10:15 AM Subject: [vicsireland] Re: Well positioned in Dublin and Cork with GPS Hi folks! Yes, I will add my congratulations to the previous ones. It's a very thorough report and you've obviously put a lot of pioneer work into boosting it in Ireland. Just a couple of thoughts on the receiver and downloading Loadstone. I'm using the Globosat receiver, which is slightly larger than the Holux, maybe the size of a fat matchbox, but it doesn't give me any problems with reception or linking to the phone. In fact, I didn't even have to set up a Bluetooth pairing, which I did with my headset. Loadstone recognized it right away. It comes with a Velcro cover which I usually attach to a strap of my back pack. I'd say the easiest way of putting Loadstone on your phone is to download it strait on to it from the website. However I'm not sure which Talks version is required to access the web with your phone. I managed it with Talks Premium. And here's a question for the 3 Loadstoneers. According to the report only one of you used a headset. How did that work for you and how did the other two go about it. Personally I've a bit of a problem with using the headset. Of course it's the only alternative to constantly holding the phone up to your ear, but I find that my hearing is slightly impaired when I wear it. Although it doesn't even fill out the ear like a walkman earphone does, it affects my directional hearing. Say I have someone walking in front of me, I can't tell where exactly they are in order to overtake them. Also I walk very slowly because it's harder to tell upcoming obstacles. That's really put me off using it a lot. It would be interesting to know if any of the 3 testers are GDO's and if cane users and GDO's make different experiences. I would assume that a GDO might have less of a problem with using a headset.

Januar 2007 22:46 To: vics Subject: [vicsireland] Re: Well positioned in Dublin and Cork with GPS Hi Ronan This is a very interesting report on Loadstone and it seems to be of huge benefit to blind people especially since Loadstone users can gather points of interest and share them with other users. I have been using loadstone and a Holux GPs receiver since last week and so, I'm still familiarizing myself with the program but, so far, I have been very impressed with its capabilities. If you know of any settings within loadstone that I should change for use in Ireland or have any useful tips, they would be great.
