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%.

The mouse does 0.001J work on me while the button is rising again, but I have not noticed any invigorating effects from this.

Note that I have ignored the work required to move my finger, i.e. I have assumed that I am 100% efficient (an approximation that my colleagues would question).

All suggestions for refinements to this calculation will be gratefully ignored.

wow, very helpful indeed, how come this never came to my mind? –  Tomarinator Apr 27 '12 at 7:20

Because you haven't spent a lifetime as an experimental scientist? :-) –  John Rennie Apr 27 '12 at 7:29
    
...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 at 2:43
