Effective and usable user interface and interaction design is essential for desktop, web and mobile devices. And it's critical for a growing number of devices and platforms. In recent years, we have seen the rapid proliferation of products with integrated digital user interfaces. Led by consumer electronics, and quickly cascading to appliances and commercial, medical and industrial applications, a new product without an integrated touch screen seems behind the times. And the rapid emergence of gestural and other “natural” user interfaces that utilize the physical dynamics of the human body will depend on a solid understanding of ergonomics and physical human factors.
Our work for Pediavision is a good example of integrated product development. The new Spot vision screening system, shown above, lets untrained community volunteers easily and quickly detect several vision issues in children including near-sightedness (myopia) to eye misalignment (strabismus). With a scan time of one second or less, Spot delivers accurate results and allows for the screening of hundreds of kids within hours. In developing Spot, our integrated team worked together to ensure that Spot's sophisticated technology was made simple through familiar and ergonomic form factor and a user-friendly interface design. Our goal was to make the new system easier to use than a camcorder.
As product developers, we're very excited about the new opportunities to enhance the user experience. We've also learned by experience that there are unique challenges to creating a device that reflects effective and integrated interaction design. And that our processes and our core expertise need to grow. That's why we've built our team to include specially trained interaction designers working together with industrial design and engineering team members to optimize interactions between physical and digital interface elements. Bresslergroup's process of integrated interface and industrial design is based on an iterative methodology that is adopted from agile software development methods. Usability is the focus of this approach with the rapid and iterative design “sprints” result in multiple kinds of prototypes to evaluate interactions with hardware and software-based user touch points. Providing these integrated deliverables throughout the process leads to better user experiences through effective system level evaluation and decision making by the development team.
