We’ll discuss Consumer products such as home lighting and heating how technical architecture and business models shape controllers are growing in popularity. Across many UX, and how IoT blurs the line between product and industry verticals, sensing, tracking and actuation are service experiences. We’ll look at the need to give users enabling smarter use of resources, just in time processes transparency around how complex systems work and and predictive maintenance. share data, in particular in relation to GDPR. And we’ll set out the challenges of designing distributed user All of these have users, who want products and services experiences across multiple UIs, and show how some which are useful, usable and satisfying to use. Mass- companies are tackling the challenges of designing for market consumers may have quite different needs both hardware and software in parallel. from industry specialists. But there are many common challenges in designing the user experience of products NB: we interpret IoT loosely to refer to connected products which span both hardware and software. and services enabled by connected hardware in general, whether or not they communicate using open internet protocols or have a direct internet connection. Claire Rowland is a London-based product/UX strategy consultant specialising in IoT and hardware-enabled services. She is the lead author of Designing Connected Products: UX for the consumer internet of things (designingconnectedproducts.com) published by O’Reilly. She has a particular interest in taking connected products from an early adopter user base to the mass market. Before launching her own consultancy (clairerowland. com), she worked on energy management and home automation products as the service design manager for AlertMe.com, since acquired by British Gas Hive. Previously, she was head of research for design consultancy Fjord, where she led EU-funded R&D work investigating UX for interconnected embedded devices. She has worked in UX design and research for mobile, multiplatform and web services since 1997.

User experience design is concerned with creating products and services which are: Valuable/useful: they fulfil a genuine need for a particular group of users or customers; Usable: the target users can use the product effectively to achieve their objectives; and Engaging: satisfying or pleasurable to use People often assume UX refers to software UIs. But a user’s experience with a product or service is usually shaped by many factors, for example: The product’s fit for their needs How reliably it works How fair pricing is perceived to be Other offline or online interactions with the provider alongside the main applications, for example purchasing, order fulfilment, and customer support. Some of these factors are beyond the conventional Fig 1. The Elvie pelvic floor trainer from Chiaro Technology remit of UX designers. They illustrate that UX involves https://www.chiaro.co.uk collaboration between the entire product team.

This looks at the whole lifecycle of a user’s experience with a needs careful planning and development. service, and how all the different components of the UX function together to deliver the service.

So user experience is the whole thing, it is the product, the product should be the experience. And the better that is, the better the product feels like a real experience then the better it feels like one product and not multiple things stuck together.” Ben Levy, Chiaro Technology: makers of the Elvie pelvic floor trainer and another new product due for release in 2018.

For example, hubs in the home are often unplugged when someone needs a socket to plug in a vacuum cleaner, and doesn’t realise that this plain white box is keeping the heating or lighting working. Network connections introduce potential points of delay or failure. And the relationship between the customer and provider is not a one-off transaction but the ongoing delivery of a service.

  • Design Thinking and Beyond Strategies for Innovation
    Design Thinking and Beyond Strategies for Innovation Great design improves product quality, increases customer satisfaction, and creates more cost-effective processes. Great design can also drive outsized profitability and investor returns. As a result, the concept of “design” has evolved from initially addressing the visual aspects of a product—physical or digital— to revolutionizing companies in transformative and strategic ways. These dynamics are best articulated within Design Thinking, an approach codified by IDEO and further shared at the Stanford d.School, as well as at many other design-oriented schools. Human-centered design thinking has evolved into a broad set of problem-solving approaches that are having a positive impact on technology, retail, health care, education and virtually all sectors of our economy. Our view is that companies employing design thinking are likely to be leaders in their industry and are developing an ardent eco- system of customers, vendors and stakeholders. La Honda Advisors LLC is a registered broker-dealer | Member FINRA/SIPC | LaHondaAdvisors.com 1 At its core, design thinking starts with a focus on the user or customer; hence, “human-centered design.” Companies with a design focus develop solutions in a streamlined, expeditious and convenient manner—often incorporating stylish packaging and/or new types of product interfaces. While many early adopters of design-thinking strategies include companies in the consumer electronics, hardware and consumer banking areas; today, the new frontier of design thinking has expanded into enterprise software, cloud computing, health care, retail, telecommunications and other industries in need of improving product delivery, customer experience and supply chain logistics.
