Employment

2001-Present

Position: Advisory/Senior Human Factors Engineer
Employer: International Business Machines Corp.
Project(s): IBM Voice Products -- Customer Focus
Location: Boca Raton, FL

Scope and Influence
Jim has led the user interface design of products for numerous high-profile customers (including Nextel, AAA, Philips, Thomson, and Hertz), based on thorough user research and collaborations with those customers. He has used his deep understanding of customer needs to drive speech development activities, and has used his deep knowledge of speech technologies and user interface design to craft compelling solutions that delight our customers. Jim receives many requests every year to review SUI designs for customer applications, with those requests coming from both domestic and international sources, within and across IBM divisions. Jim’s work has spanned many industries, including telematics, entertainment, travel, financial services, energy, telco, road service, and consumer electronics. Designated three times as an IBM Master Inventor, he has had 83 patents issued by the US Patent Office to date. A prolific researcher and writer, he has published (to date) 6 book chapters, 26 refereed scientific articles, 46 professional conference papers, and three books: (1) Practical Speech User Interface Design, (2) Quantifying the User Experience: Practical Statistics for User Research (co-authored with Jeff Sauro), and (3) The Excel and R Companion to "Quantifying the User Experience: Practical Statistics for User Research (co-authored with Jeff Sauro).

Impact to IBM
Jim’s work has resulted in the delivery of voice applications that satisfy the complex, multiple objectives of IBM's customers, end users, and IBM. High customer satisfaction has resulted in significant repeat business from our clients. The Nextel applications received JD Powers Best Telco rating.

Key Activities
IBM’s strategy for integrating its speech technology into the enterprise space has been strongly influenced through the involvement of Voice Services engagements. Jim has been involved in this effort since its inception. He has been the lead HF designer of voice applications developed for high profile IBM customers, ensuring that designs reflect the unique business needs of each customer, are consistent with industry best practices, and result in high customer and end user satisfaction. Jim’s contribution to the services teams he works with include a very broad range of activities used to implement a user centered approach to application development, as well as the detailed design of every aspect of the user interface. The activities often start with educating IBM’s customers on the importance of a user centered approach to voice application development, gathering customer requirements and the design and presentation of vision clips. This is followed by the activities required to implement a high quality speech application – call flow design, script writing, early low-fidelity prototyping using paper methods or VoiceXML coding, complex grammar coding, voice talent coaching, audio post-production to ensure appropriate system timing, and usability testing. Note: In 2006, Jim joined IBM Services full time in the Conversational Speech Solutions department. He continues to advise IBM product development on the design of future products, but his primary focus is on customer engagements.

2000-2005

Position: Advisory/Senior Human Factors Engineer
Employer: International Business Machines Corp.
Project(s): IBM Voice Products -- End User Focus
Location: West Palm Beach and Boca Raton, FL

Scope and Influence
As the Human Factors (HF) lead for all Voice Middleware development and through his patenting and publishing activities, Jim became well known internationally as an expert in Speech User Interface (SUI) Design and core speech technologies. Through his writing, teaching, and development activities, his influence crosses site and divisional boundaries. Jim received an Execute Now! Division Award for his HF leadership on the first product release of WebSphere Voice Application Access (WVAA).

Impact to IBM
Through Jim’s efforts and within the constraints of conforming to the W3C standards, IBM has incorporated best SUI design practices into the fundamental architecture of speech browsers, and has validated the accuracy of our built-in data types. The continuously updated SUI design best practices plus training materials are assets available for immersing developers in good SUI design. Jim’s SUI design expertise has influenced the requirements for the voice application development tools (see section on Developer Focus below).

Impact to Field of Human Factors
Publication of the MOS-X (a psychometrically validated method for measuring user response to artificial text-to-speech (TTS) voices) in The Journal of Speech Technology. External conference publication of discoveries in the appropriate timing for the presentation of global commands.

Key Activities
Jim’s work in this area began with the first release of WebSphere Voice Server (WVS), and has included all WVS releases, WVAA, and Natural Language Understanding (NLU). He wrote the first chapter in IBM’s VoiceXML Programmer’s Guide in 2000, based on literature reviews and coordinating inputs across disciplines and divisions. The chapter has been updated for each subsequent release of WVS, based on the results of Jim’s empirical investigations of many specific UI component designs, and his SUI design and evaluation of many voice applications written and deployed for large IBM customers (see section on Customer Focus below).

Jim has contributed consistently to the improvement of IBM’s core speech technologies through the application of expertly designed Human Factors engineering experiments and methodologies. He conducted a large series of experiments to develop and tune IBM’s VoiceXML built-in grammar types, coordinating work between research and development, leading to improved speech recognition for applications written on our platform. Jim has also conducted numerous user listening studies (lab and web-based) to evaluate IBM and competitor’s Text-to-speech (TTS) technologies. In order to systematize this effort, he developed a new rating method (MOS-X) and continues to improve on that method as more information on the human interaction with synthetic speech is required. Jim is often asked to consult in the design of experiments and statistical analysis of core embedded speech technologies as well.

2001-2005

Position: Advisory/Senior Human Factors Engineer
Employer: International Business Machines Corp.
Project(s): IBM Voice Products -- Developer Focus
Location: West Palm Beach and Boca Raton, FL

Scope and Influence
Jim is well known throughout IBM as an expert in the voice application development process and the tools required for the rapid and efficient production of well designed applications. Jim has been the HF lead for all aspects and all releases of IBM's Voice Toolkit, including standard VoiceXML, WVAA, and Natural Language Understanding (NLU) tooling. Jim’s consistent focus on the application developer user experience contributed to the evolution of the voice tooling from a text based set of tools to graphical based tooling. Jim played a key role in moving the Graphical Call Flow Builder from a VoiceXML-centric design, to one that requires no knowledge of VoiceXML. This evolution began with the VoiceXML tools, and extended the application of graphical tooling concepts to grammar building and NLU call routing applications. These innovations have lowered the skills and experience required to develop speech applications, a primary marketing requirement. Jim developed a 5-day SUI design class that includes both lecture and labs. By invitation, he has taught the class to IBM and Business Partner developers in Japan, China, and England.

Impact to IBM
Jim’s efforts have produced highly usable tools to support rapid IBM and customer production of VoiceXML code and associated development activities (e.g., rapid production of placeholder audio, grammar testing, working with pronunciations). The graphical tools were favorably reviewed in Speech Technology Magazine. Favorable responses have been received from developers such as Karl Roberts (Digital Union, an IBM business partner): Regarding Voice Toolkit documentation and ease of use – “I've spent a lot of time looking [for VXML best practices info], and I've found the documentation that comes with the IBM VoiceServer SDK (free) really good. I'm not sure you can download it separate, but it's not just VXML tags in there. It goes into structure, timing, best practice, what to avoid etc. The IBM Voice Toolkit (separate prod and free) makes building voice apps really easy and with components your apps are really modularized and structured. The kit is really good, in 7 minutes you can be up and running with your first app.”

Key Activities
Each version of the toolkit has benefited from the results of usability evaluations designed and conducted by Jim, and market research activities he has participated in (surveys, focus groups, and competitive analysis). Jim consults with the programmers developing all voice tools with a user interface. Jim wrote the first version of the Getting Started Guide delivered to drive the end-to-end scenario based development with the toolkit. He keeps the guide current to reflect improvements and enhancements to the end-to-end scenario. He has also written tutorials teaching how to code VoiceXML prototypes that embody the Human Factors best practices developed through his work with the consumers (end users) of speech applications, and how to write a natural commands shell around a directed dialog application.

Jim’s externally published work on usability satisfaction measurement has been referenced and endorsed in national and international usability standards. His position on the UCD/UX council has allowed him to extend his influence to an even greater extent within and outside of IBM. Jim is the current chair of the workgroup on usability metrics run under the auspices of the US National Institute of Standards and Technology. He has played a key role in past council activities to work out UCD/UX development processes, and led the development of website training materials for the estimation of sample size requirements for all types of usability studies. In 2001, Jim received one of the first UCD Team Awards for this effort. He is currently the SWG representative on the integration of UCD/UX into OID processes, and was recently invited to lead the work on IBM’s corporate user guidelines for web application design. Jim receives many invitations every year from external groups to publish papers, join editorial review boards, participate in conference program committees, chair conference sessions, review book proposals, and to review draft standards. Most recently, he has co-written a chapter on sample size estimation for the International Encyclopedia of Ergonomics and Human Factors with Carl Turner (State Farm) and the internationally renowned usability guru, Jakob Nielsen (Nielsen-Norman Group).

Although never released as a commercial product, the Human Center project (including HC Markup) provided the developer experience needed to successfully commercialize IBM's speech technologies in later products such as dictation systems and voice servers.

1993-1994

Position: Advisory Human Factors Engineer
Employer: International Business Machines Corp.
Project(s): Simon Personal Communicator
Location: Boca Raton and West Palm Beach, FL

Scope and Influence
Based on Jim’s company-wide reputation as an expert in UI designs for touchscreens and design for usability, he was invited to join the development of Simon – the first cellular-phone based personal communicator. IBM and BellSouth collaborated on Simon (designed by IBM with a BellSouth logo). As the lead HF designer in a small IBM development group led by Frank Canova, Jim had total control over the external design of resident software PIM applications and significant influence on the hardware design.

Impact to IBM
IBM received industry acclaim for this visionary, award-winning, highly usable product. Industry awards included Best of Show at Comdex 1993, 1994 Popular Science Best of What's New award, Grand Winner of the 1994 MAX award, and the 1995 Byte Magazine Award of Distinction. Journalists had high praise for the product’s ease of use, such as: Impact to Field of HF Engineering
Iterative design and evaluation of the first personal communicator, a product now recognized in the industry to have been years ahead of its time. Presented paper at Human-Computer Interaction International '93.

Strong application of up-front usability methods, including literature reviews; scenario based design and test; and comprehensive task analysis and low-fidelity application prototyping.

1990-1992

Position: Advisory Human Factors Engineer
Employer: International Business Machines Corp.
Project(s): PS/2 Models 90/95, PS/2 Model 57, ThinkPad 700 and 750
Location: Boca Raton, FL

Responsibilities
Consulted with engineers and programmers regarding IBM PS/2 computer product designs - designed, conducted, and analyzed experiments to resolve product design issues - presented results to upper management - made significant contributions to body of human factors knowledge - wrote computer programs as required for data collection and analysis - continued to conduct research in the measurement of product usability - technical lead for six-member usability team.

Scope and Influence
For the ThinkPad 700C, Jim brought together the IBM Research team developing the pointing stick (i.e., TrackPoint) and the Personal Systems team developing the ThinkPad 700C laptop computer. He overcame strong Development opposition to the TrackPoint at the eleventh hour (primarily due to concerns about its impact on keyboard manufacturing cost, but also concerns from the Yamato HF lab regarding its immediate usability) to bring the device to market.

Jim led the HF activities for IBM's first multimedia computer (PS/2 Model 57 Ultimedia). He conducted early customer interviewing as the HF leader for IBM’s first attempt to gather Quality Functional Deployment measurements, used to focus customer requirements. Findings from usability testing influenced manufacturing line processes regarding treatment of external multimedia controls. Received usability leadership award.

Jim also led the hardware HF evaluation activities for IBM’s first tablet computer, the ThinkPad 750C, and a similar special-bid tablet computer designed for long-haul truck drivers.

Upon his return to Boca from Research, Jim led the HF activities in the development of the PS/2 Models 90 and 95. He received an ESD Division Award for usability leadership in this project.

Impact to IBM
The TrackPoint is widely considered one of the most important IBM innovations in the ThinkPad product line, contributing to the hundreds of design awards received by the ThinkPad from its first release in 1992 to the present, including the PC Magazine Technical Excellence award in 1993. The experience gained with the tablet computers paved the way to later design success with the development of the Simon and ThinkScribe products.

The PS/2 Models 90/95 had superior HF engineering of components (display, keyboard, and mouse) and documentation. Information Development adopted the strategy Jim recommended of reducing the cloudiness count (an automated readability measure), which resulted in a Model 95 cloudiness of 5.6 and Model 90 cloudiness of 4.3 – a substantial drop from the Model 55 cloudiness of 9.5. This contributed to (1) an Infoworld rating of excellent for the new publications, a 4-point jump from previous ratings of poor, (2) a 1992 Society for Technical Communications award, and (3) the IBM Atlanta HelpCenter reported an 80% drop in customer calls about publications.

Impact to Field of Human Factors
Iterative design and validation of the TrackPoint -- a completely new pointing device. Publication of innovative soft keyboard layouts for stylus-based user interfaces. Discovery and validation of the utility of the cloudiness count for the competitive evaluation of user documentation. Made presentations at 1990-1992 Human Factors Society Annual Meetings and 1990-1991 CHI conferences. Received Society for Technical Communications awards in 1991 (Distinguished) and 1992 (Merit).

Scope and Influence
Based on Jim’s growing reputation as an expert in usability methods and metrics, he received a one-year temporary assignment to work in the Human-Computer Interaction lab at the TJ Watson Research Center in Hawthorne. While there, he conducted seminal research that advanced the techniques of usability engineering (a Research Division activity) and, at the same time, had a major effect on the OS/2 office application development effort in the Application Systems Division (for which he received an Application Systems Division award).

Impact to IBM
Competitive information about strengths and weaknesses of the current IBM solution (PROFS), the Mac solution, and the Windows solution provided significant input to the design of the OS/2 solution.

Impact to Field of Human Factors Engineering
The basic work on usability measurement and problem discovery that Jim conducted during this temporary assignment led to papers published in the early 1990s that continue to be frequently cited -- specifically, Lewis (1994) -- a paper problem discovery sample size estimation and Lewis (1995) -- a paper on the psychometric qualification of various user satisfaction instruments developed during this project. Note that the questionnaires from Lewis (1995) developed during this project (the PSSUQ, CSUQ, and ASQ) have been endorsed for use in the applicable ANSI and ISO usability standards. These are the papers that established Jim’s international reputation as an expert in quantitative usability methods. During this time period, Jim presented research papers at Interface '89, HFES '89, and at the Hawaii International Conference on System Sciences.
