Overview
Mobile users often multitask while traveling, but their fragmented attention can lead to issues like missing their stop. To address this, we conducted qualitative research to understand how people multitask while on public transit in Taiwan.
I will cover three key insights with two significant challenges, and provided design recommendations for public transit agencies and mobile service providers in this case study.
Overview
Mobile users often multitask while traveling, but their fragmented attention can lead to issues like missing their stop. However, HCI researchers have put relatively little attention on developing technology to help with travel multitasking.
To address this, we conducted field observations and interviews to understand how people multitask while on public transit and what challenges they face.
We uncovered four key insights, identified two significant challenges, and provided design recommendations for public transit agencies and mobile service providers.

People today can multitask almost anywhere and anytime due to advanced technology.
Travel-based multitasking behavior is defined as when “individuals endeavor to do multiple things concurrently while on the way to destinations.”

However, travel multitaskers’ fragmented attention will likely negatively impact their travel tasks, e.g., by causing them to miss their stop, lose belongings due to packing them up in a rush, or even hurt themselves due to hurriedly disembarking.
While public transit has become a space where people use a wide variety of information technologies, the infrastructure and services that support this ubiquitous behavior have lagged far behind.

Understanding travel-multitaskers
To answer these questions, we conducted a qualitative study consisting of shadowing and semi-structured interviews with travel-multitaskers to observe their behaviors and experience when taking public transports.

Understand public transports environment
Different transportation modes and environments will lead to prevalent travel-based multitasking practices and activities. For example, while car users must actively participate in driving and navigation, public transit allows passengers to undertake productivity tasks while traveling.

Participant recruitment for this study was divided into two stages, based on our goals and approaches to data collection and analysis.
For the recruitment, we distributed recruiting ads via four main channels: Facebook groups with themes related to public transit, Facebook pages intended for recruiting research participants in our country, the researchers’ personal networks, and word of mouth.
Questions include
● Demographic information
● Travel behavior in the past six months (i.e., types of public transit they frequently took, and their journey purposes, frequencies, and timings);
● Frequent choices of tasks on public transit
● Tendency to multitask

The main objective of the shadowing study was to observe people’s multitasking behaviors, including their attention-switching, task choices, technology choices, and responses to the dynamic environments within public-transit vehicles. These observations allowed us to investigate their in situ behaviors that would have been difficult to obtain through retrospection, such as autonomous responses to environmental stimuli.

Semi-Structured Interview
After each shadowing session, we invited each participant to a semi-structured interview lasting between 90 minutes and two hours to capture their multitasking experiences on public transit over the preceding six months.
The goal of the semi-structured interview was to explore their experiences, rationales behind choices when multitasking, feelings toward incidents, and any challenges they had.

We used ATLAS.ti to code our shadowing and interview scripts.
We would assign the quote with a related 'code,' like using a thematic tag to describe the quote. After we analyzed the data of our first three interviewees, all researchers would discuss and group each code. Therefore, we could use a bottom-up method to find their behavioral patterns and challenges.

Participants sharing this pattern habitually performed such tasks while traveling with little regard for whether they would be completed.
One of our participants (P5) said, "I probably have checked some stock stuff at that time. It just occurred to me that I haven’t done this today and so I did it.”

Participants who shared this multitasking pattern expressed their motivations negatively (e.g., avoidance of idleness) and positively (e.g., seeking a feeling of being productive). Their main goal was to fill dead time, and they were open to switching to other tasks, as long as doing them helped them fill the time.
As P10 said, "I am a person who can’t tolerate being idle, I feel that I just had to find something to do, even including playing games."

This pattern of travel multitasking was motivated by the participants' heavy workloads and desire to complete them during the travel.
P15 reported squatting down among a crowd of passengers in a moving train to use her computer: "There happened to be some urgent business to deal with at that time. I had to turn on the computer to send a document to a client because there was no way to use my phone to do this. "

The loud environment, unreliable stop-announcement systems, and malfunctioning auditory systems can make it difficult for participants to receive the cues to disembark. This situation worsens when participants are multitasking.
For example, P02 shared that, "I had to look out the windows. Some buses don’t broadcast [stop announcements], don’t know why, maybe it’s broken, so I can’t focus on listening to the radio."
From the original assumption, Pet owners have difficulty in tracking pets’ medical records and manage their documents.
From the interview insights, I got specific pain points that users share, such as pet owners having difficulty keeping pets' physical records and transferring documents with different vets.

Concerns about Privacy
Some participants expressed concerns about their privacy and personal image when they were aware of other people on public transit.
For example, P26 said, "If I need to pay with a credit card for online shopping, I will try to use it at home because I have no way to ensure my privacy on public transportation fully."

Interestingly, however, some participants took other people on public transit as positive pressure to perform tasks such as reading or studying to present a positive image to other passengers.
P14, for example, mentioned one occasion on which she wanted to project a diligent attitude toward learning: "I have some strange insistence, that is to be perfect in front of strangers, so that people next to me will think, 'Oh, this young lady is so hard- working, she is not looking at the people around her but at her books.' Anyway, I forgot to get out of the train at that time."

Show real-time updates about a vehicle’s current location, speed, and upcoming destinations that passengers can access, for example, with browsers, official transit-service apps, third-party apps, and vehicle-mounted physical displays of existing and new types, which would allow passengers flexibility in accessing the required information across channels, and reduce the unnecessary attentional cost of switching between devices.

Future technology can consider implementing customized reminders.
For example, a countdown feature could be included to give passengers a sense of urgency about wrapping up their tasks and packing their belongings.

After conducting observation research with travelers, I became more interested in field studies.
I took courses at UT Austin to conduct a parent-child field study to understand their interactions with mobile phone usage, regulations, and each other. This experience deepened my fascination with the dynamics of user behavior and technology.

With 30 participants generating a vast amount of interview data, it was crucial to collaborate with other researchers to define categories, codes, and quotes for grouping our final findings. Through multiple meetings with UX researchers and professors, we identified behavioral patterns and their challenges.
