Visuals
Welcoming page
When a user has visited the Start page and clicked on the Start button, your agent should start by greeting its user. But we would also like to show a webpage that welcomes the user and is shown while the greeting pattern c10 is active and ongoing. Additionally, the new page provides the user with the ability to start talking by clicking on the microphone icon.
As before, we need to introduce a rule for generating a webpage. The head of this rule should be page(c10, _, Html). We advise you to reuse the same overall structure for the Prolog rule as for the Start page you created in the html.pl file. Add your rule for the welcoming page also to the html.pl file.
The main requirement for this page is that it shows a microphone icon that the user can use to start talking to the agent. All you need to do for this is to create a page with a header. A second requirement is that your page should not have a button for moving on to the next page! Progress should be made by talking from now on! Ideas for this page could be to show a greeting and introduce your agent by showing its name. Next, we provide some suggestions on how you could proceed with creating the welcoming page for your agent:
...
As a start, consider the condition that needs to succeed when this page is generated. Hint: look at the rule for the Start page and check out how the first argument of the page/3 head of this rule is reused for defining the condition for showing the page.
...
Think about the design of your welcoming page. What should the page look like? You can show text that introduces your agent somewhere, using the agentName(Name) fact to retrieve its name, for example (if you do, also take into account what should happen if the agent has no name!). You can use https://www.w3schools.com/bootstrap4/bootstrap_jumbotron.asp, https://www.w3schools.com/bootstrap4/bootstrap_alerts.asp, or other Bootstrap components to display the text. You can add other visual elements using images, or add more advanced layouts for your page. Check out the [TBU]Visual Support Guide for more on how to use these components.

Whether you followed our suggestions above or not, make sure your welcoming page looks inviting!
