In my previous post, I discussed how technology can be a bane to a driver. In this post, I discuss how technology can help the distracted driver.
This articleResearch Scientist at the Virginia Tech Transportation Institute, applications that can be used to reduce driver distractions associated with cell phone use. These applications vary with respect to what they do.
Drivesafe.ly is a software application that reads out texts and emails to drivers, without drivers having to touch their cell phones. Dial2do is a similar software application that allows drivers to listen to and send texts and emails, tweets etc. The perceived advantage of these apps is that these are hands-free. This reminded me of Henry Thoreau’s quote “It’s not what you look at that matters, it’s what you see”. These applications certainly facilitate “looking” but may fail to promote “seeing” because drivers are still using their cognitive resources to think about the world outside of the driving environment via the texts and emails. Therefore, though these apps may not necessarily help with cognitive distractions (because drivers are still listening to and comprehending texts and emails while driving), it is one step in the right direction – which is, helping drivers keep their hands in the steering wheel and their eyes on the road.
Zoomsafer is an application that can be downloaded onto your phone and provides auto-replies to incoming texts and calls stating that the driver is driving and is unable to receive calls and texts. TrinityNoble’s Guardian Angel MP is another application that locks the cell phone when the car is traveling above a certain speed limit, thereby disallowing any cell phone usage.
These applications can be used by a conscientious driver to parents wanting to enforce ‘no-texting while driving’ on their children to companies wanting to avoid lawsuits that arise due to motor accidents involving use of cell phones.

Mr. Mouhamad Naboulsi’s recent post in the Cognitive Engineering and Decision Making group on Linkedin bought my attention to this article. Roximity and Ford have partnered to make an app that would be available in cars that bring location-based deal alerts to drivers. The information from the app in your smartphone will be displayed on Ford’s dashboard. You can find more information on this here.
So do we need any more distractions on the road?

A month back, I was travelling outside the United States and attempted to buy credit to place internet calls, to connect with my family. I entered my payment information and received a message stating that “We were unable to process your request. Try again later”. I repeated this 5 times (because I kept receiving this message) only to find out that I have been charged 5 items. However, I was able to chat with a live agent and get this issue resolved in no time.
Now, this is not the first time I have chatted with a live agent to help me with my queries. I have used this feature for shopping enquiries to billing enquiries.
Chatting is so much more hassle-free in comparison to waiting for an agent on the phone. Advantages of getting support from live agents over telephone support include:
- It is faster.
- It does not disrupt customers’ workflow. That is, chatting with a live agent can be easily done in conjunction with other tasks and do not require the extra step of placing a phone call. This really fits the model of today’s technology users who are trying to accomplish multiple things with their computer.
One of the enhancements that I would desire as a customer is more feedback as to what the live agent is doing. Though the live agents ask you to wait while they are investigating the issue or query, better indicators as to how long this process would take would be beneficial. These status indicators could be automated and can be easily integrated with the chat engine. This way, the customer knows how long the process would take and what the chat agent is doing.
I also wonder about the usage statistics on live chat agents and whether this appeals only to certain demographics of the user population. For example, older adults may prefer having a conversation on the phone versus chatting on the computer.

The BRIC nations (Brazil, Russia, India, and China) are projected to be the world’s largest and most influential countries by 2050. Undoubtedly, as these countries undergo advancements, several domains/industries would benefit from the application of human factors and ergonomics principles.
Agriculture has been the backbone of Indian economy and hence it was not surprising when I came across a paper written by Saran in 1968, which discussed the design of a grain harvester for agricultural work in India. Rather than imposing a design that required altering the working position and habits of the Indian farmer, a design that incorporated the habits and usage patterns of the Indian farmer are described in this paper.
Nearly four decades after Saran published his paper, Mukhopadhyay (2006) describes the state of ergonomics in India. He discusses how ergonomics can be applied to various industries such as:
- Crafts (e.g., pottery making, jewellery making)
- Agricultural tasks (e.g., harvesting, sowing)
- Non-motorized transportation (e.g., rickshaws)
Mukhopadhyay discusses how successful ergonomic interventions in India would require raising awareness about ergonomics to the rural people.
How can we forget India’s IT sector? The operators working long shifts in the call centers to the software developers working on projects outsourced from other countries, the Indian IT industry would benefit from various human factors and ergonomic interventions.
Last but not the least, increasing consumerism in India also offers a plethora of opportunities for human factors and ergonomics research, that would take into account the unique needs of this market.

Blogging on Division 21 talks from the American Psychological Association Annual Meeting – Use of Smart Phone Apps as Health Interventions
Dr. David Gustafson from the University of Wisconsin-Madison discussed how mobile phone apps can be used to help recovering alcoholics from relapsing by using virtual communities.
The advantages of the application include:
- Use of GPS to detect whether the user is near a high risk location such as a liquor store and allow the user to get support. Specifically, a screen with options to call or text a friend comes up when the user is near a high risk location.
- Capability to chat with individuals with addiction problems thereby gaining peer support.
- Distance counseling via video chat.
- Capability to complete weekly surveys: this information is used by the computer intelligence to detect relapses.

Blogging on Division 21 talks from the 2012 American Psychological Association Annual Meeting: Technology and healthcare
Dr. Daniel Morrow from the University of Illinois discussed how technology can be used to improve the collaboration between health care providers and diabetes patients as well as to improve patients’ adherence to medications. The highlights from his talk are described below:
- U.S. healthcare system assumes patients to be active, aware, and health literate.
- Older adults with diabetes take an average of 4-5 medications per day.
- Self-care imposes a lot of cognitive demands on the elderly. Think of the working memory demands associated with having to keep track of when each medication need to be taken.
- Non-adherence to medications and inadequate plan for taking medications are problems. Nearly 30% of hospitalizations are linked to non-adherence.
- Communication from health care providers is inadequate – often times, information provided to the elderly patients are poorly organized with no check as to whether the patients were able to accurately comprehend the information that was transmitted to them.
- It is therefore important to reduce the cognitive load on the elderly patients and help them collaborate easily with their providers to plan their medication routine.
Dr. Morrow discussed the design of an EMR-based system called the Medtable to aid the elderly population. This system has 3 interfaces: a set up interface that would allow clinicians to set up patients’ medication list, a collaboration interface that would allow clinicians to reconcile medication information with patients and educate patients on the times they need to take medications, and finally a print-out interface that allows clinicians to provide a printout of the medication scheduling information to patients to take home. This system is under clinical investigation currently and the expectation is that this would improve patient outcomes by improving the collaboration between patients and health care providers and reducing the cognitive demand on the patients.
