Khaberni - A recent research study has uncovered an unusual aspect of smartphone usage, which involves the physical effort that fingers exert during daily interactions with screens, during which users spend long hours scrolling, pressing, and browsing.
Researchers from "Aalto" and "Leipzig" universities have utilized a new artificial intelligence model named “Log2Motion”, aimed at converting phone usage logs into precise kinetic simulations resembling human hand movements during app usage.
This model works by creating a digital structure that simulates finger movement on the screen, with the ability to actually operate applications via a software simulator, allowing for the tracking of kinetic effort for each swipe or tap.
Not All Movements are Equal
The results showed that some usage patterns require more effort than others, as it was found that vertically scrolling up and down is more strenuous compared to other movements.
Clicking on small icons or reaching the corners of the screen also requires extra effort from the finger.
According to the researchers, these differences may seem trivial each time, but they become more apparent when repeated hundreds of times daily with intensive use of short-content applications.
A Tool More Beneficial to Designers Than Users Currently
The researchers point out that the importance of this model currently lies in supporting app developers, by designing user interfaces that are less exhausting and more comfortable, instead of relying solely on click data without understanding the accompanying physical effort.
The model could also contribute to enhancing the experience for people with disabilities, through simulating different situations such as impaired mobility or the use of prosthetic limbs, helping to develop more inclusive applications.
Potential Broader Uses
This type of simulation can be extended to include daily usage scenarios, like browsing the phone while lying down or using it with one hand, which are common situations among users.
The study concludes that interacting with the phone isn't just a passive digital activity, but involves repetitive kinetic effort that may seem simple but accumulates over time to pose a real burden on users.
