I'm designing a mobile web form where a user will fill in various personal information and finally add a signature, where users with touch capable devices will be presented with a full screen view where the user writes their signature. However, we need a fallback solution for the users who don't have a touch capable device, a checkbox is what's being considered now. So basically a user taps the checkbox instead of entering their signature for these scenarios.
Question is now how I should lay it out, and what copy I should use to communicate it thoroughly to the user.
The problems I see are either
- That the checkbox label could quite easy be quite long to communicate its functionality, that is for eg. "If you can't enter a signature check the box to confirm the entered details".
- That I need to break up the fallback in two steps: "Can't add signature?"-link --> "I confirm the entered details are correct"-checkbox.
- That I formulate it in a way which makes all users tap it, eg "I confirm that the entered details are correct"-checkbox. But then the non-touch enabled device users could be a bit unsure to whether they've entered all mandatory input or not (which the signature isn't) without trying to continue.
Does anyone have an idea for how to structure this? Or have an insight which would go in favor for one or the other of my listed options?
Here's a WF of my idea for the form:
