Complex data input form on mobile device

Question

I need to create an Input form that allows a user with a mobile device, to insert informations with this structure:

output = {
  context: ‘Context Title’,
  products : [
       {
           name : ‘product1’,
           subProducts : [
                { name : ‘subproduct1’, rating : 2 },
                { name : ‘subproduct2’, rating : 5 },
                ...others dinamyc subprodutcs...
           ]
       },
        ...others dinamyc products...
  ]
}

The user has to insert those informations in the easiest and fastest possible way. My idea was to design the form like the picture below:

The first screen shows the "context" value. The user can change it by tapping on it. Under the context value, there is a panel where the user can pick some products. The products will be listed according to a recommendation engine, but the user will be able to search something else using a search bar.

Once the user pick a product up (action 1), a new screen takes place. In this new screen there is the name of the product as title. Under the title there is a new panel where the user can choose some Subproducts. Like the previous screen, the sub-products will be suggested by a recommendation engine but the user can use the search bar.

The user will be able to pick one or more Subproducts and he can rate them. So, everytime he choose a subproduct (action 2a, 2b), the subproduct is removed from the list and a "card" is shown at the top of the panel. The user can rate the subproduct or he can remove it by sliding the card away.

By tapping on the confirm button at the bottom of the page (action 3) we get back at the first screen. A "card" will give the user a summary information about the products he picked.

I created a little demo according on this UI. It works, but i'm afraid that is quite dispersive for the user.

Do you have any idea?

Thanks

Answer 1

As a mobile user, I don't think it is a good idea to have many new windows open when I am going through a process. What if I want to go back and change something, right? I would suggest you make it like a "slide show" form without opening new screens. Apple setting is a good example.

On the first form, you can show all the products. You can make it select-able and have a "next" button going to the next page. Since the second and third step is to select subproducts and rate them, I would suggest that you combine two of them and make it like the third step above, showing the subproduct name on the left and empty stars on the right. User can directly click the stars to rate. Then a "next" button to proceed. The final step is to show the summary that the user chose. Hope it helps.
