EXPERIENCE
CONVERGYS CORP.
Human Factors – Consultant - Professional Services Group 2009
Designed new voice application features for telecommunications IVR system. Assisted in testing and evaluating usability of existing applications.
MOTOROLA, Schaumburg, IL 2002 to 2008
Distinguished Member of Technical Staff - Motorola Labs – Applications Research Ctr.
Technically managed and led a team of Human Factors (HF) / Human Computer Interaction (HCI) members on usability and user interface design projects.
· Designed and prototyped next generation user interfaces for future products with multimodal interfaces (voice and GUI) including:
° Developed prototype Linux hardware and software for a voice media search application running on set-top boxes.
° Developed multimodal (voice + GUI) applications for Motorola Java phone.
° Developed GUI interface (C/C++, QT) to simulate phone interactions on embedded Linux devices for technology demos and usability testing.
° Developed voice controlled Roomba vacuum cleaner robot demo (hardware/software).
· Led User Experience design and evaluation projects using heuristic/expert evaluations, task analysis, cognitive walkthroughs, etc. on numerous internal and external designs including:
° Conducted the iPhone User Experience study for the Motorola Labs technology organization and CTO.
° Performed extensive usability testing on a security application for mobile devices, which allowed remote video surveillance resulting in numerous usability and design improvements and very successful demonstration to external customers.
° Evaluated and contrasted different voice recognition activation methods, and studied VUI application usability issues on Motorola cell phones.
° Performed competitive analysis on competitor and internal VUI-based phones to monitor features and plot industry direction for embedded speech applications which was used to assist strategy and decision makers.
· Collaborated with researchers in other Motorola Labs and Motorola businesses to research and develop new user interfaces (GUIs & VUIs) for applications on mobile phones and set top boxes.
· Designed and created a custom usability lab which has been used for numerous internal and external studies and by other product group as well.
· Developed automated custom test fixture for end-to-end testing of speech recognition on mobile phones that led to identification and resolution of a significant problem in shipping products.
· Developed technical guidelines and training for business staff, developers and other lab members including:
° Voice User Interface Guidelines
° Task Analyses Guidelines
° Trained team members in UI design and testing procedures especially for Multimodal UIs
· Functioned as technical reviewer on several patent committees (Applications and Human Interaction) that helped the company focus on patenting the most promising inventions.
· One patent pending from work in this time period.
MOTOROLA, Downers Grove, IL 1999 to 2002
Distinguished Member of Technical Staff - Internet Software and Content Group
Responsible for Voice User Interface grammar development, performance and tuning, and usability analysis of applications on Mya voice portal platform.
· Created first ever distributed speech recognition demo system demonstrating multimodal capabilities on a custom Nextel data network delivered on time and within budget.
· Wrote TCP/IP analysis programs to identify packet latency and loss rates on Nextel network with potential to reduce packet loss improving multimodal system recognition rates.
· Developed programs to analyze speech recognition log files for system testing resulting in significant time saving for tuning and system testing cycles.
· Improved speech recognition rates on Motorola voice platforms by over 20% by tuning applications, grammars and acoustic model selections while under intense product schedules.
· Designed call usage tracking programs for customer system resulting in enhanced understanding of caller usage patterns and application problem areas – greatly exceeding customer’s expectations.
· Developed Text To Speech performance evaluation tools for Motorola Voice Platform for predicting system load resulting in normal and worst case scenarios.
· One patent granted from work on these projects.
