UX Design: Pushing the Frontiers of Innovation

‍

What exactly is user experience (UX)?

Over the years, you must have come across several definitions of UX, some of which might have seemed cryptic. Simply put, UX or user experience is an umbrella term that considers a person’s interaction with a product or a service, encompassing the perceptions, feelings, and thoughts that arise from that interaction.

UX is shaped by factors like usability, efficiency, accessibility, desirability, and aesthetics. Its design theory crafts meaningful and effective user experiences by drawing from fields such as psychology, human-computer interface (HCI), and design thinking.

The UX design process is a systematic and iterative workflow, and designers and innovators rely on this process to create or refine products that enable users to achieve their goals in a seamless, enjoyable way.

At TG0, as experts in product design and touch and pressure-sensing technology, we have witnessed UX’s evolution and its impact through innovative products and services on diverse sectors, including healthcare and automotive. Our goal is to empower designers and engineers to rapidly innovate and create the next generation of smart, sustainable products  by integrating advanced technology with user-centric design principles.

In this blog we take a deep dive into how UX has streamlined the design process, revolutionised product development and design, and facilitated intuitive and seamless experiences for users. But before we do that, let’s talk a little history.

The evolution of UX: From ancient principles to modern design

The term ‘user experience’ or UX was coined by cognitive scientist and usability engineer Don Norman in 1993 during his time with Apple. Norman used the term to describe the entire spectrum of an end user’s interaction with a company’s product and services, encompassing “industrial design, graphics, the interface, the physical interaction, and the manual”.

However, the tradition of UX design – aiming to improve the quality of life – can be traced back to around 4000 BC, to the Chinese philosophy of Feng Shui. Feng Shui involves arranging one’s surroundings in the most optimal, user-friendly way to enhance the flow of energy.

Fast forward to 500 BC, where we have evidence that the ancient Greeks demonstrated remarkable skill in designing tools and workplaces with a human-centred and ergonomic approach.

Centuries later, in the early 1900s, entrepreneur Henry Ford’s Model T Assembly Line and mechanical engineer Frederick Winslow Taylor’s monograph The Principles of Scientific Management played important roles in  advancing UX principles by focusing on optimising workers’ interactions with their tools and workspace.

A few decades later, in the 1940s, another car company, Toyota, pursued workplace efficiency with the creation of the Toyota Production System, which emphasised that tools should be adapted to suit workers, not the other way around.

Between the 1950s and 1970s, ergonomics and human factors gained more prominence in UX with studies increasingly focused on optimising product design for physical comfort and usability. In 1955, American industrial engineer Henry Dreyfuss, a stalwart in UX design, wrote Designing for People, a book that emphasised the importance of creating user-friendly products.

The rise of personal computing in the 1980s gave a significant boost to UX as researchers began exploring how users interact with software. This led to the development of distinct research fields, including Human-Machine Interaction (HMI) and usability testing. Around this time, Apple gained prominence with the launch of the MacIntosh, whose built-in screen,  graphical user interface, and mouse made it a groundbreaking success.

How emerging technologies are shaping the UX landscape

Cut to the present: The advancement of UX is being significantly shaped by emerging technologies like Artificial Intelligence (AI), Virtual Reality (VR), and Augmented Reality (AR). The Internet of Things (IoT) is also bridging the gap between the physical and digital worlds, embedding sensors, connectivity, and computing power into everyday objects, transforming them into “smart” devices. UX plays a pivotal role in the success of IoT solutions, ensuring that these technologies are intuitive and user-centred.

Manufacturers of IoT devices must perform a balancing act in their pursuit of product excellence, profitability, and market share. They need to produce more while being  economical, create tailored products using standard processes, and reduce technical debt (meaning they must prioritise design and implementation decisions) while also accelerating product releases to the market.

Over the centuries, UX has not only evolved in its principles but has also grown into a significant industry. This growth is evidenced by the increasing demand for user-centred design in emerging technologies, particularly within the Internet of Things (IoT). Manufacturers are now recognizing the critical importance of effective UX in achieving product excellence and gaining a competitive edge. This demand is reflected in the market's expansion, with the global UX services market valued at USD 2.59 billion in 2022 and projected to grow from USD 3.50 billion in 2023 to USD 32.95 billion by 2030, at a compound annual growth rate (CAGR) of 37.8% during the forecast period.

Achieving effective UX

As the UX landscape continues to evolve, it becomes increasingly important to focus on strategies that ensure UX remains effective and user-centred at every stage. Here are key approaches to achieving this:

• Focus on end users’ pain points: UX aims to make the entire customer journey pleasant and productive. At the outset, it’s crucial to dig deep into the end users’ needs and pain points. UX designers conduct customer interviews and create user personas to understand what truly matters to users and how they perform essential tasks.
• Incorporate customer feedback: UX design is rarely linear and often involves a great deal of iteration. Designers continuously refine products by creating and testing prototypes based on customer feedback.
• Ensure accessibility: Delivering a wholesome UX requires clearly highlighting the solution’s capabilities and benefits with straightforward language and imagery, making it easy for existing and potential customers to understand the product’s value proposition. Accessibility is essential too as UX must also consider users with physical limitations.
• Catalyse engagement: UX plays a key role in driving engagement and usage of the product. A smooth initial experience and a clear navigational hierarchy helps users quickly understand the product’s value.
• Enhance customer satisfaction: Elements like packaging, branding, and product installation, which directly impact the product’s value proposition, are integral to the  user experience and customer satisfaction.

The evolution of a product from concept to commercialisation involves a series of steps that require close collaboration among multiple stakeholders, including UI/UX designers, product designers, product managers, and users.

While research, prototyping, testing and iteration fall under the purview of UX, User Interface or UI design – a specialised subset of UX – focuses specifically on usability. Usability is crucial for all products with a human-technology or human-machine interface whether they are mobile devices, medical equipment, apps, websites or complex machine control systems. A well-designed UI is intuitive and efficient, enabling users to complete  tasks easily, and UI design optimises the visual and interactive elements of a digital product, including colours, fonts, buttons, switches, and  controls.

Building better products: How UX drives successful product design

Product design involves creating a product with a focus on its functionality, aesthetics, usability, and ergonomics, while UX serves as the backbone of the product design and development process, with the power to make or break a product. A negative UX creates numerous pain points for users, who may struggle to navigate a device due to confusing structures or features. When combined with inefficiency, inaccessibility, or lack of visual appeal, the product won’t stand a chance in the market.

UX and product design share significant overlap in roles and functions, leading many experts to consider them two sides of the same coin. Key similarities include:

• Leveraging design thinking and user research to understand the user, challenge assumptions, and redefine problems.
• Engaging in quantifying and qualifying research.
• Using a similar set of tools to get the job done.

However, a key difference lies in the focus of each discipline. While UX examines a product from the perspective of usability and usefulness, prioritising customer satisfaction, product design must balance user needs with business goals. Product designers must consider economic, marketing and legal constraints, as well as industry trends and stakeholder needs, in their work.

UX drives successful product design by prioritising a human-first approach from the start of the development process. This approach is crucial for delivering meaningful and impactful experiences that resonate with users on a deeper level. UX offers product designers valuable insights into what their audiences need and want in the product they are developing, ensuring that designers stay aligned in creating a practical and usable product. Additionally, it fosters innovation in product design by challenging conventional paradigms and inspiring out-of-the-box thinking.

One of the easiest ways to integrate UX into product design is by incorporating user feedback. This collaborative approach  between users and designers, known as design thinking, includes the stages of empathise, define, ideate, prototype, and test. For product designers, it is essential to include users from the very first “empathise” stage.

At TG0, we believe that identifying and resolving usability issues early in the development process can mitigate the risks of failure and save innovators and entrepreneurs both time and resources. When users find a product to be intuitive, easy to use, and effective in addressing their problems, their relationship with the product becomes strong and enduring. A positive association can lead to increased sales, higher product adoption and stronger brand building.

In summary, the benefits of integrating UX early in the development process include:

1. Reduced development time and costs.
2. Significant improvement in sales and revenue.
3. Enhanced customer engagement and satisfaction.

The evolution of UX in the age of Industry 4.0 and IoT

UX has evolved significantly, keeping pace with changing user expectations and rapid technological advancements. The integration of IoT and Industry 4.0 has brought about a fundamental shift in manufacturing, enabling smart factory strategies where connected digital equipment communicates and shares data over high-speed networks.

The use of smart sensors in IoT has had a positive impact on the quality of products and services while reducing costs, increasing production output, and enhancing efficiency.

A McKinsey report has identified four key disruptive technologies of Industry 4.0

• Connectivity, data, and computational power: Cloud technology, the Internet, blockchain, sensors.
• Analytics and intelligence: Advanced analytics, machine learning (ML), AI
• Human–machine interaction: Virtual reality (VR) and augmented reality (AR), robotics and automation, autonomous guided vehicles
• Advanced engineering: Additive manufacturing (such as 3-D printing), renewable energy, nanoparticles

Owing to its ability to create satisfying, seamless, and intuitive user-product interactions, UX design has become the foundation of successful technological products and platforms. However, as a dynamic field, UX is constantly evolving. In the coming years, emerging technologies and climate change concerns will drive the continued adaptation of UX within smart industrial environments.

Here’s what the future of UX looks like

• Data-driven design: Big data and analytics will play an increasingly significant role in UX. Data-driven design, which relies on user behaviour and preferences, along with methods such as A/B testing (comparing two versions of the same product), heatmaps, and user feedback, will become even more critical for refining the user experience.
• AI-led ultra personalisation: Artificial Intelligence (AI) and machine learning (ML) have catalysed a radical change in UX and UI, delivering hyper-personalised, streamlined, and immersive user experiences. AI analyses historical data to predict user behaviour, making interfaces more intuitive and user-friendly. The integration of AI and ML enables UX designers to gain deeper insights into consumer mindsets, leading to improved decision-making.
  At TG0, our specialised software integrates touch-sensing hardware technology with AI/ML algorithms, resulting in reliable, cost-effective, and visually appealing products. Our expertise spans sensor fusion, AI/ML, data analytics, and capacitive sensing, allowing for the detection of X, Y, and Z movements for versatile applications. By leveraging ML and AI, our touch-sensing surfaces optimise their ability to detect interactions enhancing personalisation efforts. This approach enables signal processing that requires fewer I/O ports and electrode connections, resulting in better performance and reliability at a fraction of the cost.
• Haptics: Haptic and gesture interfaces have introduced a new dimension to UX. By utilising touch, force, vibration, and motion, these interfaces create tactile and gestural interactions with digital systems, enhancing the user’s sense of realism and feedback while enabling intuitive and expressive engagement. Haptics is driving accessibility and inclusivity, going beyond sight and sound in human interaction with devices. As the demand for a more intuitive user experience in human-machine communication systems intensifies, haptics will take centre stage.
• Voice User Interface (VUI): VUI utilises voice commands to enable users to interact with digital products and services. It is becoming an integral part of how users engage with smart devices (Alexa and Siri are already household names). Successful UX may integrate a combination of sensor interfaces and voice commands, giving users the freedom to choose the mode of interaction that is most convenient for their specific situation. However, VUI poses several challenges including:some text
  • Integration: Compatibility issues can arise when integrating with IoT devices,
  • Confidentiality: Users may be concerned that the device is eavesdropping, which can make their data vulnerable to privacy and security breaches.
  • Processing limitations: VUI systems may struggle to process accents and background noise,
  • Misuse: Children can use the technology to buy products online without parental approval.
    
    
• AR-VR-led immersive experiences: These technologies have expanded the realm of UX, creating new ways to design experiences and interactions while narrowing the gap between the physical and digital worlds. Augmented Reality (AR) has revolutionised the visualisation of complex designs by overlaying digital information onto the real world. Both AR and VR have inspired UX and product designers to explore new territories of spatial, multi-sensory, and movement-based interaction. Those working or playing in the virtual reality sector have long pursued a more immersive experience. At TG0, we have successfully developed the eteeController for VR, which allows users to feel fully present in virtual worlds. This represents a significant shift from existing market options, where traditional controllers tend to be large, heavy and complex to use. With TG0’s touch, pressure and finger sensing technology, users can navigate through virtual reality and metaverse environments as easily as they would in the physical world.
• Minimalist design: Sustainability is more than just a buzzword in the manufacturing world as we confront the devastating consequences of climate change. UX will increasingly emphasise simplicity, clarity, and functionality, resulting in clutter reduction, energy conservation, resource optimisation, performance enhancement, and a more timeless aesthetic.
• Seamless cross-platform experiences: As users switch between devices – such as desktop computers, smartphones, tablets, and wearables – as well as operating systems like iOS, Android, Windows, and macOS, they will expect a fluid experience. UX is moving towards platform-agnostic, seamless interactions, empowering users to complete a task regardless of the device or operating system.

Key challenges for UX designers in the IoT landscape

Every job comes with its own set of challenges, and for UX designers it’s far from a cakewalk, especially when dealing with IoT devices. These products are complex as they support both human-device interactions and device-device interactions.

In the coming days, the following areas will demand special attention:

• Reduction in size and energy consumption: Size does matter! With technological advancements, there will be growing demand for smaller and more compact devices. Users will increasingly prefer streamlined designs over traditional human-machine interfaces (HMIs) that are bulky and occupy excessive space. Additionally, traditional systems often consume substantial power due to architectural limitations, and sensors used in remote or portable systems often have limited power availability. Therefore developing energy-efficient sensors and their associated processing systems not only enhances performance but also addresses pressing environmental concerns.
• Budgetary constraints: High-performance sensors can be expensive, so balancing performance with cost-effectiveness is essential to make sensing technologies viable for widespread use.
• Enhancing user satisfaction without added complexities:  IoT devices are inherently complex and need to be designed accordingly. However, the user interface or UI –  the first point of contact between users and IoT devices – should be clean, simple, and intuitive. This allows users to easily navigate and interact with the device. By eliminating unnecessary features or functionalities, designers can reduce the cognitive load on users, enhancing overall satisfaction.
• Prioritising security: Security is a critical concern for IoT devices, and users must feel confident that their data won’t be misused. Implementing secure design practices, conducting regular system updates, and clearly communicating security features to users can help build trust and ensure user confidence in the product.
• Compatibility and connectivity: Connectivity is arguably the most important aspect of IoT products. Additionally, the UI/UX system must be compatible with various devices and platforms to ensure users have a seamless experience across different platforms.
