In a previous article, I talked about how notebook computer users don’t really care how long their notebook batteries last. This was because users will plug in the AC adaptor whenever possible, thereby making these notebook computers nothing more than portable desktops.
Here is another observation: many notebook computer users prefer to use an external mouse instead of the touchpad or pointing stick that comes built into their computer.
Why is that?
I asked one such person whom I have observed rolling an external laser mouse on a sofa. Her response was that it was easier to use an external mouse.
So the question is this:
Is there an inherent usability problem with the touchpad/pointing stick?
The question is interesting because its answer may indicate a business opportunity.
Here is a non-rigorous validation:
Every notebook computer comes with a mouse device. Yet, travel(small size) mice are popular items at computer stores.
I would assume that these travel mice would only be used with notebook computers.
I don’t know what new innovation can make notebook pointing devices (touchpads/pointing sticks) more usable. Apple’s multitouch is probably not a solution. I have it on my MacBook Pro and have trouble using it. One reason is that I don’t remember the gestures: think Palm Graffiti language.
So if you are reading this, start thinking. There is an entrepreneurship opportunity here somewhere…
