I'm currently working on the UI wireframing for a taxi booking and sharing app.
When a user requests a seat in a taxi you've booked, then you receive a notification.
Prior to making a decision of accepting or rejecting a request, you get to see the implications that it has on your existing journey. Now I am having difficulty showing this in the app. In the instance above, I've simply highlighted the changes in a different colour. The things that change include your journey details change, price, journey time and distance. Secondly if you had 4 seats available in your taxi, it gets reduced to 3.
Would there be a better way of showing a before/after snapshot (i.e. what the journey looks like now and what it would look like afterwards)?
I was advised to use stock tickers, and a combination of color and icons to represent the change, but how would this look like with my current interface?
