Service Bubbles

Trevor Orsztynowicz

Lots of the discussion surrounding conversational interfaces is centered on text and the kinds of interactions that medium will enable. The idea is by starting with a system that enables organic behaviour, you allow your service to address generic needs and requirements. The behaviour that people exhibit in your UI allow you to learn, and that learning leads to augmentation. With text, that interaction is augmented by layering in some kind of domain specific language or if you’re lucky a system that understands natural language.

Today, those languages and commands are being interpreted using chat bots. Having a bot that can respond to certain types of commands or intercept words and trigger an action are becoming commonplace on platforms like Slack, but have existed for a really long time on IRC channels.

Underlying all of this is the need and desire to achieve some kind of outcome. Conversational interfaces provide a generalized way to achieve a goal. In this world, the UI allows you to accomplish something, but can also represent the outcome itself.

While text is an incredibly powerful tool for asking for information, it’s a very limiting tool for conveying results. In many of these instances we want to return images. But images are also limiting in their own way. While they can describe data that is very dense, they’re also fixed and non-interactive; it’s impossible to transform or interact with an image in the same way that even a rudimentary weather app would provide.

Instead of popping out to email to get your ticket, we want to bring the data forward. What we should be able to achieve is an element you can interact with, delivered in-line, as a response to our question, or a prompt to our user.

A new chat primitive

The solution to this problem is a new primitive for chat we call service bubbles. A service bubble is an interactive widget that appears in-line with traditional text, images, and video. By adding this 4th mode of interaction, we give conversational interfaces the flexibility of text and the density of images, all in a tidy package.

If we apply this to our earlier example, your flight details can be delivered as a ticket bubble in line, which you can scrub through for flight details and present to the airline.

At Bench our customers routinely connect businesses financial accounts. Adding a new account through a conversational interface using text would expose sensitive information. But with a service bubble we’re able to capture and keep this interaction self-contained to the widget, and then have that bubble represent the state of the connection after we’re done. In this way, our UI not only represents the tool designed to achieve an outcome, but it represents the outcome as well.

Today some modes of this exist, but they require you to leave the chat interface. You can send links to forms or directly into some state of an application where you can take these actions, but this type of behaviour limits the user experience. Another massive loss is the separation of history, by breaking up what you did into separate tools, when you really want the history of your chat to update in response to state.

The major benefit of chat is having a free flowing conversation which allow people and machines to respond where appropriate. By implementing the service bubble concept, we can provide users with the powerful organic behaviour that text provides, with rich interactions of specialized applications.
