Powershell - how do I.....

I'm using the following

$prompt = @"
***************************************************
*                                                 *
*    s = Search AD for deleted users              *
*    r = Restore user account                     *
*    x = exit                                     *
*                                                 *
***************************************************


"@
Clear-host
Do{
      $originalcolor = $host.UI.RawUI.ForegroundColor
      $host.UI.RawUI.ForegroundColor = "Yellow"
      $choice = Read-Host -Prompt $prompt
      $host.UI.RawUI.ForegroundColor = $originalcolor
      Switch($choice){
            s {Get-ADObject -Filter {displayName -eq "John Doe"} -IncludeDeletedObjects}
            r {Get-ADObject -Filter {displayName -eq "John Doe"} -IncludeDeletedObjects | Restore-ADObject}
            x {break}
            default {write-host "Invalid selection, please try again." -ForegroundColor Red}
      }
}Until($choice -eq "x")

To search for and restore deleted ADObjects, specifically user accounts.

However, as you can see I want to make this into a menu that can be used by others, and I don't want them playing with the code so I would like to make it ask them to enter the display name rather than it being hard coded in the script.

Does anyone have a way of doing this without making the user have to do more than select the option and type the name?
