I’ve been working on the page turner with @bphelps2521 and @joshua-8, and we wanted to give you a quick update on this project.
We tested using a rubber wheel or arm to turn a page by “swiping” or rolling across it like in the videos we found. It worked around 95% of the time on some newer books, but it had much lower reliability on others. We’re thinking the reliability of the page turning needs to be high for the device to be useful.
We found that we can much more reliably get a single page if we lift and “peel” the top page instead of sliding it against the other pages to separate it.
We prototyped “peeling” pages with a suction, and with a removable paper-safe adhesive.
Here’s a link to a paper on a page turner that uses an adhesive.
Unlike the suction, the adhesive would sometimes need to be replaced, but it’s quieter, simpler, and more reliable.
A couple questions:
- Would the client be okay with a paper-safe removable adhesive being used on her books? If no, we can try to build a suction-based system, however this was presenting design challenges that we’re not sure how to work around.
- Should we provide a chin switch, or does the client have her own? Either way, we will provide a 3.5mm jack so it can be easily switched out if her preference changes.
