Is Horse the New Mouse?

· Score: 3, Informative
Europhysics News (2004) Vol. 35 No. 6 A new computer mouse called Horse C.J. Snijders and P.C. Helder, Erasmus MC, University Medical Center Rotterdam, the Netherlands. In the early 60's Doug Engelbart, a scientist at the Stanford Research Institute in California, invented the computer mouse. This may certainly be seen as one of those brilliant tools we hardly can do without. However excellent the functionality of the mouse--we all use it with great ease--its recent form can also be a significant source of discomfort.
Repetitive movements cause physical complaints. This is one of the causative factors of Repetitive Strain Injury (RSI) or Occupational Overuse Syndrome (OOS) [1]. Rigid work patterns and prolonged periods of heavy work load can result in physical stress. Personality aspects are also considered to play a role in the development of RSI [2]. About 20% of the working population has complaints related to the neck-shoulder-arm region and overuse complaints can be the result of using the mouse. This is why a biomechanical research program was started by Erasmus MC,University Medical Center Rotterdam, the Netherlands.
Biomechanical model The present study has identified one cause for several physical problems in the neck-shoulder-arm region. Based on a pilot study a hypothesis was introduced that forceful gripping or pinching goes with tension in the deep neck muscles. To investigate this, blood flow velocity was measured in the region indicated in Fig. 1 (with permission from Sobotta,Atlas of Human Anatomy). The drawing shows the costoclavicular gate between clavicular bone and first rib (see circle). Neck muscle tension results in a narrowing of this gate and thus impingement of the subclavian artery and vein. This conclusion is supported by a biomechanical model of the aetiology of tennis elbow [3]. It describes the role of extensor muscles in the hand and lower limb and substantiates the finding that restriction of blood flow is caused by forceful pinching. Therefore we conclude that certain force application by the hand is related to tension in the deep neck muscles which explains a variety of shoulder- and arm complaints.
Design of a computer mouse called "Horse" The use of a conventional computer mouse requires continuous lifting of the fingers. This results in excessive use of extensor muscles to avoid unwanted switching which can be seen as a possible cause of tension in the deep neck muscles. It was therefore decided to design a mouse that does not provoke extensor muscle activity. This new concept is called Horse in view of its functional design: the palm of the hand as well as the middle three fingers "sit" on the main body while thumb and little finger rest at a lower level at the side as if supported by stirrups (Fig. 2). Thumb and little finger work together to realize optimal control in the horizontal (X-Y) plane. The design of the Horse allows for the three middle fingers to adopt a flexed position to relax the tendons. A major part of these fingers rests in a more or less vertical position.

In view of this supported position of the hand and fingers, extensor muscles can relax. Extensor action is no longer required with the palm of the hand and fingers resting on the Horse. A light flexing action of the top of the fingers is sufficient to switch. This action results in a force on the touch switches situated at the lower end near the tips of the fingers. These switches react on touch force only which reduces or virtually eliminates the movement of the tendons when switching. Moreover, complete support of the fingers will reduce the necessity of co-contraction of the intrinsic muscles of the hand [4]. Other features as a result of the design of the Horse are: * a better stability control in the X-Y plane * the possibility to reduce friction of the Horse on the table Fig 2 Thumb at the side, major part of the three
In Chinese, there is no generic aunt or uncle label. There are specific names for my mother's older sister, mother's younger sister, and mother's brother. There are also corresponding names for their spouses.
Unforutunately, I can never rememeber which name is which.
no, QUEEN Amidala was never mentioned by name in ep. 4, but jesus christ, who do you think gave birth to the PRINCESS?
I totally agree with the fact that any slashdotter should know what happens next, but I thought that Princess Leia was adopted by some other royal family?
Yeah.. found it. She's raised on Alderan by this dude.
My burglar alarm went off while I was on a business trip, and the police felt I was irresponsible for going out of town and leaving my wife alone to watch all three babies.
I don't understand, how did the police manage to not notice that your wife was home with the kids?
Right, I totally agree with you. I was under the understanding that patents on medicine lasted 7 years or something. I guess if a doctor discovers some procedure and there is a way of patenting it, the same type of rules should apply
Can you imagine if the doctor who developed organ transplant surgery patented all his findings and demanded huge royalties each time a transplant was carried out?
Wait, isn't that one of the reasons we have patents? What if you discovered a better way of doing organ transplants? Wouldn't you deserve to be compensated for your work?
Right, but they're not just offering a plug-in. It's an officially sponsored plug-in. I presume they'll have their technical support trained to help customers with Firefox.
Imagine this. A troubled customer calls tech support about a spyware issue. Support offers an alternative browser. Customer (hopefully) enjoys the new experience and tells their friends. Isn't this what Firefox needs? Exposure to the public? Well, it's already started to happen and offical promotion by technical support shows that Firefox is getting more and more exposure.
I (and many other/.ers) can only hope that the Mozilla foundation can handle the accelerating exposure.

Apparently he IS your uncle.

Which result you get is still uncertain.
Everybody else: "My motherboard is Dell."
Seriously though. When was the last time you typed slashdot.com into your browser? I mean, it shows up as the first thing when I type s.

Better yet, no more need to worry about that pesky sex drive. =/

Who is ESR??
You are right. They use a sliding scale percentage.
The percentage goes down as the sale price goes up.
Wait, isn't that one of the reasons we have patents? What if you discovered a better way of doing organ transplants? Wouldn't you deserve to be compensated for your work?
You mean Bookmarks right? =P
The logical answer is yes. Assuming they do so, Speakeasy is doing two important things for the Firefox devs.
From what I understand, this is good for the Mozilla foundation.

I, for one, welcome our new Management overlords.
It's funny because, judging by the first paragraph in the article, Sony is aplogising not to the consumers, but to their shareholders.
God didn't give us birth control, but hopefully by the time we achieve immortality, we'll figure it out.
Does Wikipedia have a system in place to remove the tag on good links? Is there a moderation type system to determine which links are good?
Just curious
I believe the author of Shareaza was an Australian. It is now open source.
I live in Ontario and use Telus Mobility. I can add unlimited SMS for $10 a month.. $3 per month sounds nice.
BTW I don't really use textmessaging. I'm just curious. for $3 maybe I would.

Check the commercials against Ikea. Funny stuff.
The thing is Y2K compliant! Look there's a statement in the top-left corner of the page.
And check out the FAQ someone decided to include pictures. hehehe
and BTW, this is not worksafe =\
