Experiments[rosenb (and intuition) indicate that adjusting a physical |
65 |
|
slider is much easier than adjusting a virtual slider on the |
66 |
|
screen with a mouse. Despite this, virtual sliders or scrollbars |
67 |
|
are far more common with computers than physical sliders, |
68 |
|
probably due to economics. Adding a new virtual slider to a program |
69 |
|
costs next to nothing, while adding a new physical slider for |
70 |
|
each user amounts to a considerable sum of money. |

Still, complicated devices such as computer mice and joysticks |
73 |
|
can be cheap due to commodity economics; the cost of user |
74 |
|
interface devices has little to do with manufacturing and |
75 |
|
much more to do with the number produced, as the development |
76 |
|
costs are amortized over the whole production. |
77 |
|
Thus, computer mice cost approximately $10-$30, joysticks |
78 |
|
some more, steering wheels even more, and specialized |
79 |
|
input devices such as Monkey Bones 2 REF can cost up to $22,000. |
