Understand user and usability issues surrounding the development and deployment of kiosks and Interactive Voice Response (IVR) systems.
Experience from the Lake Tahoe Coordinated Transit System.
- Keep the kiosk user interface simple. The largest challenge with the kiosks was the user interface. The initial user interface required eight to nine steps to book a ride, and many passengers were not successfully completing all the required steps (though many of these thought they had successfully booked their trip). Just one month after the initial roll out, the stakeholders decided to shut down the operation of the kiosks. They redesigned the user interface so that booking a trip required only three steps. The kiosks were re-released about one month later with the updated interface. The stakeholders strongly recommended using focus groups comprised of riders of the system to assist in the design of the interface for the kiosks and the phone reservation system. Focus groups could have eliminated the need to reprogram the kiosks after the initial deployment.
- Understand who your users are. Lacking a sufficient understanding of the demographic characteristics of their transit riders, the CTS stakeholders overestimated the riders’ willingness to use a computer system to book rides. In particular, two demographic issues affected riders’ propensity to use the kiosks. First, a key factor was the age of riders and their related lack of exposure to computer systems. Secondly, since many of the riders are visitors to the area, they are unfamiliar with the system and may need some time to become acclimated to the new system. The fact that potential riders are on vacation poses another challenge, as tourists are less likely to want to spend time trying to figure out the system. Stakeholders noted that a demographic study of riders is an important step in understanding who will be using the system, and this information can be used to design a system that is best suited to their needs.
- Recognize the importance of the appearance of the kiosk. Based on feedback from riders, stakeholders indicated that some users were unsure of the specific function of the kiosks, and this affected their use of the technology. Some stakeholders felt that there was too much emphasis on restaurants and attractions on the screen, and this may have contributed to riders’ confusion about the primary purpose of the kiosks. Moreover, the appearance of the kiosk cabinet housing also added to their confusion about the purpose of the kiosk.
- Test technology systems prior to implementation. The CTS originally included an Interactive Voice Response (IVR) system to provide customers with access to trip scheduling and dispatching services by phone. However, shortly after roll-out, the system experienced technical problems, which resulted in a significant drop in ridership. The IVR system was removed from operation indefinitely until the problems could be resolved.
