In what content would my target audience be interested?

Hello,

I'm selling a product … similar to a mouse pad, but for the arms.
Now, after doing a lot of keyword research, I have a huge list with good keywords and probably 3 or 4 groups of clients that might be interested in my product:
1. Employees with a computer job.
2. Gamers
3. People with skin problems / allergies.
4. Private people who want more comfort in the computer.

What I lack, are good ideas for content / content strategy. Sure … things like ergonomics in the workplace, skin problems, etc., everything would work. But would people really read them?
What other ideas / options are there, in which my potential audience would be interested? (Maybe a little more exciting than the ergonomics of the workplace … ;) )

Thank you,
Chris
