How to Design An Intuitive Conversational Interface Experience: 6 Useful Tips

How to Design An Intuitive Conversational Interface Experience: 6 Useful Tips

by Adriana Cacoveanu on Jan 16 2018

It's no longer a matter of “Why?”, but a matter of “How?”. The conversational interface trend isn't going anywhere but... UP.

So, if you want to keep up with the break-neck pace at which your competitors will be launching their own chat-based apps this year, you first need to:

put an end to your “to go or to go conversational?” dilemma. You only have one option...

Then, to start focusing on more pressing issues:

  1. what are the user experience challenges to expect when designing conversational user interfaces (CUIs)?
  2. what are the best practices to adopt for creating state of art conversational experiences?
  3. how do you design a... conversation, after all? One that's natural, seamless, quick and ideally convenient for the user?

And once you've pondered on these 3 questions, go ahead and turn the following “enlightening” answers into your trump cards for designing your own rival to Siri, Alexa and or OK Google.

1. Put Together An Exhaustive List of Hypothetical Use Cases 

In other words: leave no dead ends in your chat-based app's script. No weak links that could impact your conversation's fluidity.

And how do you get “unpredictability” down to zero? By getting knee-deep in user research work. 

Invest plenty of time and teamwork in identifying all the possible use cases that your chatbot's scrip should cover... impeccably!

How will users react to hypothetical scenario A? And what queries is he/she likely to input in scenario B? What “tricky” request will he/she make?

Once you have THE list at hand, filling in your script with copy will sure feel just like putting the puzzle pieces together. 

2. The Onboarding Experience: Be Sure to Give It Special Attention 

The more straightforward your chatbot's onboarding message is, the more chances there are for the user to interact with your conversational interface.

In other words: take no chances, don't try to play smart, resist the temptation to turn your app into a “guessing game”!

Let the user know which are your bot's functionality and key features and how precisely it may serve him/her via:

  • a speech bubble
  • an intro message
  • a suggestive animation

… from the very beginning.

3. Focus on User Convenience When Designing Your Conversational Interface

And convenience in conversational UX translates into minimal user input!

Now here are 2 best practices to consider for achieving the proper level of user convenience:

  1. keep your copy crystal-clear and straight to the point: avoid ambiguity at all costs, like giving more than one answer to the same question or answers completely out-of-the-conversational-context, irrelevant to the user's intent
  2. keep the user's input to a minimum: the less your customer will need to type in/interact with your chatbot, the better; aim for “yes/no “questions and avoid overburdening them with too many choices to scan through and to select from

Extra tip: make your content ideally easy to squeeze through; keep your sentences conveniently short, thus anticipating that the user might head straight to the call to action.

Why should you discourage him/her with an almost impenetrable block of text to keep on scrolling through?

4. Set Up Visual Cues-Based Replies to Your Users' Queries

How would you improve readability in “conventional”/non-conversational design? You'd instantly reach out to your not-so-secret trump card — the whitespace — right? 

Well, in case of a conversational design, your trump cards are the visual cues.

Here are 2 examples of how/when you can use them for boosting readability and turning your conversational interface into a truly intuitive AI experience:

  1. Use them to assist your customers when in need; for conveying bite-sized information and addressing your users' queries in a highly intuitive way. Maps, charts, infographics images, GIFs will be far easier to “digest” than chunks of text and far more efficient for relaying the message
  2. Use them to convey... emotions: whenever words are not enough to convey the feelings you need to convey (e.g. giving them a warm welcome into the app), go with... visual cues; and emoji make the handiest of them all

5. Empathy Is Key to Designing a Human-Like Chatbot

A natural conversational interface experience is a human-like one. And a “humanized” AI app is one that easily passes the empathy test. 

Now here are 2 suggestions on how to “inject” empathy into your chatbot:

  1. Read the script out loud: how does it sound? Would you say those lines to someone close to you? Do they sound natural enough? Or rather robot-like? Is the conversation fluid enough?
  2. Pay attention to context and adapt your script accordingly. Now you wouldn't want your app to give a robotic-like, impersonal reply such as “I hate to hear that” to a user writing: “I feel a bit dizzy”. It goes without saying that you should anticipate all use cases and user queries and have all the context-suitable replies ready (popping up a map showing the nearby hospitals in this case, for instance)

6. Embrace the “Less Typing on the User's Side” Principle

For the less they'll need to type, the more fluid the whole conversational UX is going to be.

And, in this case, by far the most popular example to inspire you is Linkedin messager's automated replies. See how it provides users with plenty of choices, right at hand (multiple buttons, “attach a file” option, automated replies etc.)? 

In other words: whenever suitable, automate... everything and aim for user convenience at its best!

These are the “tips and tricks” that you may want to consider if you're determined to create a highly intuitive conversational interface experience for your chatbot's users. Ponder on them and see how you can adapt them to your own app's and use cases' scenario.

5 Drupal Blog Posts That Have Made It to the Favorites Lists of All the OPTASY Team Members this Month
This month's "surreal" events have shaken the world as we had known it. They have "closed" us safely inside our homes, stopped us from doing many of what we had considered as "ordinary" activities, but it hasn't stopped us from... reading. And Drupal blog posts are always on our reading lists. We've recently compared our lists of favorites, put together OPTASY's monthly selection, which includes those Drupal articles that most of our team members found valuable, and... we're now ready to share it with you. Here they are: OPTASY's top 5 favorite Drupal tutorials, guides and insights in March.   1. Getting Started with the Gutenberg Editor in Drupal We, too, have recently shone some light on the Gutenberg module for Drupal 8, one of the latest layout tools added to Drupal's toolbox.  A tool aimed at improving the editing experience in Drupal. While doing our research, we “bumped into” this blog post. And it quickly became one of the team's favorite Drupal blog posts of the month since:   it's concise and to the point it's neatly structured it includes all the information that anyone interested in taking this Drupal page builder for a “spin” could possibly need From:   installation to configuration to the final step, where you use the Gutenberg Editor to publish content on your Drupal landing page   … the blog post takes you through all the steps you need to take to get yourself familiarized with using this site building tool. Source: Opensource.comNote: we loved that the Opensource team insisted on highlighting those Gutenberg features that are specific to the Drupal integration only (you won't find them in the WordPress plugin):   granular permission placeholder content the possibility to add Drupal blocks inline 2. Drupal Website Accessibility in Review: Key Features & Useful Modules “How to implement web accessibility?” “How do I make my website WCAG compliant?” Any responsible Drupal website owner asks himself this kind of questions these days. No one wants to risk getting sued for having underestimated the importance of color contrast. Or the importance of displaying web forms that can be easily filled in by all the website visitors. But what if your CMS helped you check off most of the recommendations on the W3C accessibility checklist by... default? This is what Drupal 8 helps you with.  And this is what the Wishdesk team's post, one of the best Drupal blog posts in March, is all about. It makes a useful inventory of Drupal's built-in accessibility features and contributed accessibility modules. “What makes Drupal 8 accessible out of the box and easily extendable, helping you reach even the “nice to have” accessibility levels on your website?” The post has all the answers to your question. Source: WishDesk.com It outlines all of Drupal's built-in features for accessibility:   the accessible inline form errors the shiny and new Olivero front-end theme the ALT text for images required by default in Drupal 8 ...   Then, it covers the key contributed modules that you could enable to further boost your website's level of accessibility: CKEditor Abbreviation, Siteimprove, Automatic Alternative Text, HTML Purifier, etc. A useful checklist to keep at hand whenever we add or improve accessibility on our clients' Drupal websites. 3. Using Drupal in a Pandemic, One of Our Top Favorite Drupal Blog Posts The Lullabot team stroke again. Just that this time it wasn't a valuable Drupal tutorial/technical guide that they put together, but a list of Drupal mindsets that we can all apply in the context of the COVID-19 pandemic. And the similes that they found and pinpointed are just fantastically... appropriate. Here are just some examples:   3.1. As Drupal contributors, we've come to learn that we can also help the community by stepping back and letting other contributors step forward. Likewise, we can still join the fight against COVID-19 by simply... staying home.Source: Lullabot.com   3.2. Over time, we've learned that by “getting off the Drupal island” and partnering with other communities we could help push Drupal forward. Likewise, these days we need to step out off our own circles of needs and put our skills and technical knowledge to work for others in need. Or for those who are directly involved in providing relief.   3.3. “Community” is the best term for defining Drupal. It's a community of contributors working together and not a community of individualistic “rock stars” contributing, each, merely for his/her own fame and gratification. Likewise, there's no way that we can fight this pandemic by being selfish and egocentric. We need to join forces. To join the global community of people who're applying the “social distancing” measures. It's something that we can all do and that we can all benefit from.   And these are but some of the Drupal-specific principles that the Lullabot team managed to turn into clear responses to the crisis that we're living. We invite you to discover their other Drupal lessons that you, too, can easily turn healthy mindsets these days.   4. Set Up Product Attributes in Drupal Easily & Boost Online Sales A useful step-by-step tutorial on how to set up product attributes on a Drupal Commerce website. Why has it made it to our list of favorite Drupal blog posts of the month?   because it tackles an all too common “To do” on the lists of our Drupal projects: setting up product attributes properly, in a way that's easy to manage by the site admins/editors and easy to scan through and to select from for the end-user because it's clearly written, with lots of helpful print screens and a logic structure    In short: it's an honest tutorial, written in a clear and accessible style, that shows you exactly how to set up product attributes in your online Drupal store. From the point where you add a new product attribute, all the way to the final step, where you connect that attribute to the specific product variation type on your e-commerce website. Source: Druedesk.com   5. Concurrent Editing in Drupal 8: Possible or Not?   “How do you implement concurrent editing in Drupal? Is there a solution for it already in Drupal core?” This is the question that the QED42 team asked themselves when they faced the challenge of setting up a system where multiple content creators could access and edit, simultaneously, yet independently, layouts and widgets in a Drupal app. Source: QED42.com And it's this problem, that they had to find an answer to while working on their project, that made them share their findings in the form of a useful blog post. A post that brings forward 3 modules that the team evaluated as possible solutions for concurrent editing in Drupal:   Paragraph Frontend UI Conflict Content Lock   What makes it set itself apart from other Drupal blog posts that we've read in March?   it's focused on a real Drupal limitation ... one that many Drupal teams struggle to find an answer to while working on their clients' projects: how to enable distributed editorial teams to edit content simultaneously, with zero conflicts that might arise from their concurrent actions it presents multiple possible Drupal solutions to it, each one with its strengths and weaknesses it shares their own custom solution to this Drupal shortcoming: turning the widget creation into a decoupled, separate node, and referring all those widget nodes into the Layouts   Useful, usable, relatable. In short, it's a Drupal blog post valuable enough to add it to our own resources list.   The END! Your turn now:  How does your own list of March favorites look like?

How Creating a Mind Map Helps You Make Your Website More User-Friendly
The line between useful and... useless (or pushy or simply annoying) is thinner than you think. That's why creating a mind map that aligns your site's content structure with the user intent is... critical. "Whether you’re a product owner or designer, you don’t want your website to be a maze with nothing but frustrating blind alleys.” (source: altexsoft.com) And there's no guessing work or discouragingly complex process in identifying the current user flow on each web page on your website: Just take a look at the behavior flow report in your Google Analytics. No rocket science here... Take it from there and:   identify the roadblocks restructure content on each page so that it matches user intent and is fluid and easy to read But let us give you a hand with that. With mind mapping your current customer journey and planning its improved version: In this respect, in today's post we'll:   give you the “anatomy” of a user-friendly website: what elements make a website, well, user-friendly? define mind mapping with respect to designing the user experience on a website teach you how to create a mind map: an easy step-by-step guide show you how to use a mind map to make UX improvements on your website   1. The Anatomy of a User-Friendly Website: 4 Essential Features “A vague objective leads to poor results.” There's no point in creating a mind map that would hopefully make your website more user-friendly if... you're not quite sure what key elements make a website user-friendly. So, here's the list of must-haves for any website aspiring to deliver a great user experience:   1.1. High Speed It's no news to anyone: the page loading time has a huge impact on the user experience. Unnecessary interactive elements, that don't match users' needs and don't play any role in the conversion process either, will only get you a clunky and... well... slow website.   1.2. Useful Features And “intuitive” I must add. Again, we go back to the “elements justified by the user's needs” principle: Is that slider useful and relevant for the user behavior on your website? It it too bulky, loaded with endless options that just ... discourage the visitor? You might want to re-evaluate all the features on your website: are they relevant and intuitive enough?   1.3. A Well-Structured Information Architecture Information that's:   easy to access easy to interpret   … is key for a wannabe user-friendly website.   1.4. Content that Matches User Intent If users are looking for online cooking classes, let's say — and that's precisely what you promise to deliver them — and you're only trying to sell them kitchen gadgets on your website, the only result that you'll get is them bouncing off in seconds.   2. What Is Mind Mapping with Respect to Designing the User Experience? An overly simplified definition would be: A way to brainstorm and present the generated information in a visual way. Now, since I've promised you a definition “with respect to” creating the user experience, here's a more... context-specific definition: Mind mapping is a vesatile technique where you put together a visual hierarchy of your site's present or future content. It lists out the key pages on your website (homepage, service pages, blog page, etc.),  the various relations between different web pages, the links and CTAs on each page... Source: altexosft.comIn short: mind mapping reveals how data is structured on your website. Of course, you'll then consider creating a mind map of the target version of your current website. The more user-friendly one...   3. Main Benefits of Using Mind Mapping: From Great Ideas to... Actionable Steps Finding new ideas is exciting. But jumping on every new great idea that someone in your team has, without first checking whether it aligns with the user intent, is just like... making shapes out of soap foam. Not only that they're not future-proofed, but that clutter of ideas might not work together either. By using one of the best mapping tools available online for structuring those ideas as they... pop out, you turn them into actionable steps in your strategy for improving the UX on your website. And the clear benefits to mind mapping are:   you define your ideas' roles: what role do they play in your UX strategy (if you can't assign them a role, they're just “Wow” ideas with no solid justification) you assess their value: how does implementing this new idea bubble up to the user experience? you identify the various relations between them: you might want to avoid “island-ideas”, with no connections to other ideas listed out in your mind map   4. Creating a Mind Map: 5 Simple Steps Now that you know what a mind map is and why on earth you'd bother making one, let's see how you can actually put one together:   4.1. Create a Mind-Map Template Just so you can have a basic idea of the current information architecture on your website. List out how data's being structured on your website now and how you plan to structure it for its more user-friendly future version...   4.2. Map Out Your Ideal User Flow How would you like your website visitors to engage with your content? What actions would you like them to perform? Source: mindmeister.com Once you've outlined the key pages on your website (homepage, services, features), start planning out the user flow.   4.3. Compare it to the Current Behavior Flow Available on Your Google Analytics Before you can properly map out the user flow, you need to know what's the standard customer journey on your website now. For that, just delve into your Google Analytics data and look for the user behavior report. It'll show you all you need to know about:   how users are engaging with your website's content  what paths they usually take when navigating through your current information architecture   4.4. Identify the Roadblocks The user behavior data might reveal to you some unwanted realities regarding the user experience on your website:   poorly structured content a bulky and tiresome collection of interactive elements irrelevant features (embedded videos, interactive elements, social sharing functionalities) too many tools that don't respond to users' needs   4.5. Make the Appropriate UX Decisions to Influence the User Behavior Now that you've identified the main roadblocks in delivering the best user experience, it's time to... remove them, one by one:   turn chaos into a logical content hierarchy trim irrelevant page elements, with zero value in the conversion process  adapt web pages' content structure to the needs of specific audience segments (make sure to include relevant information for those customer personas, redesign your CTAs if needed...)   5. How to Use a Mind Map to Make Powerful UX Improvements Creating a mind map is but the first step: Turning it into powerful UX decisions should be your main objective. So, the answer to the question “Are mind maps effective/useful?” is: They are if and only if you make them useful and... usable. You can turn your mind map into:   an effective sitemap a customer journey map   But let us take a real-life scenario and point out specific UX decisions that you could make with your mind map at hand. It's an example that I've run into reading Mindmaster team's great blog post: A Simple Way to Design UX, UI and CX Using Mind Maps: Say you're targeting 3 different customer personas on your website. You then need to plan 3 different user flows.  You start by grouping the web pages on your site into 3 categories, each of them corresponding to one audience segment. Then, you start doing some user behavior mapping: how do you want each customer persona to navigate to the corresponding web page so that he/she clicks the CTA placed there? Now, it's time to make some critical UX decisions:   what relations to set up between various pages on your website? You might have a user on a service page and you need him/her to visit your “get a quote” page, as well what's the best CTA design for each one of your 3 types of pages? what key information should you include on a page, depending on the customer persona accessing it? See? Not only that creating a mind map helps you put together an effective information architecture, but it's also a great technique for generating content ideas that match the user intent.   6. Final Word In the end, it all comes down to goal setting. Creating a mind map is a great way to:   understand your website goals: what type of conversion actions do you want users to perform? achieve those  website goals by delivering a user-friendly experience: content that's useful, accessible, easy to read and to interpret   The END! Do you usually create mind maps when building new websites, to ensure they'll deliver the best user experience? Or for existing ones, to improve their UX? Do you consider them critical or optional in designing the user experience? Image by Biljana Jovanovic from Pixabay   ... Read more
