# Work Done to click a mouse?

Is there any good research done to find out the work done in clicking a mouse button.

any link to that would be greatly appreciated.

P.S.

i am not too sure whether this question belongs here or not, so please let me know, if it doesnt, i will remove it,

I have already googled "work done to click a mouse" "mouse click research" and oher relevant queries on google and google scholar, but only in vain!

I think this may not be appropriate here, but we'll see what other people think. (Personally I imagine this sort of thing may be better handled by a web search.) – David Z Apr 27 '12 at 6:18
I did a google search before asking this question, but got no relevant results,and even on google scholar. anyways, i googled it again only to find the link to this question as the top result. ;-) – Tomarinator Apr 27 '12 at 6:27
OK, well that sort of thing you'd want to mention in the question. Show that you've done your background research. – David Z Apr 27 '12 at 6:29

To prove that experimental Physics is alive and well, I used my kitchen scales to measure the force needed to click the button on my mouse, and it turned out to be 100g i.e. 1 N plus or minus about 10%. The distance the button moves is about a millimeter i.e. 0.001m, plus or minus 20% (OK - you try measuring it without a micrometer to hand) so the work per click is 0.001J $\pm$ 22%.
...an approximation that my colleagues would question... Consider me one of your colleagues! A while ago I came across biophysics papers on the amount of energy (in the form of ATP -> ADP conversion) required by one of the myosin heads to produce a given force. (Or rather, they calculated or measured the force produced by a given ATP -> ADP cycle.) Given some reasonable force profile $F(t)$ exerted by your finger, an interested party could translate this to $P(t)$ and get a sense of the power required. – BMS Jan 28 '14 at 2:43
