Analysis of Laptops and Touchscreen Computers for Web Browsing Purposes
In a recent study, researchers compared the performance of participants using a laptop and a touch-screen PC in a web-based information search task. A total of 36 participants took part in a lab-based experiment, and the results suggest that traditional laptops generally perform better than touch-screen PCs.
The study found that participants using laptops retrieved more relevant elements than those using touch-screen PCs. Linear mixed-model analyses showed a significant difference in this regard (F = 6.302, p = .018). Additionally, participants using laptops bookmarked more relevant webpages than those using touch-screen PCs (F = 9.678, p = .004).
The researchers also observed significant differences across devices in pupil size variation (F = 3.692, p = .05) and EEG-based cognitive load index (F = 5.181, p = .028). Participants using touch-screen PCs spent more time on each webpage than those using laptops (F = 9.2141, p = .005), indicating a possible inefficiency in navigation and content consumption.
Interestingly, participants using laptops self-reported lower cognitive load than those using touch-screen PCs, although this was not mentioned earlier in the study. Furthermore, laptops users had smaller pupil sizes on average, which could suggest less mental effort.
However, the study did not find any significant difference in the number of webpages visited between participants using laptops and those using touch-screen PCs. It also did not investigate the impact of the computing task complexity on the performance difference between laptops and touch-screen PCs.
The study involved measuring cognitive load through self-reported scales, eye-related data, and cortical activity (EEG). While the search results do not directly compare laptops vs. touch-screen PCs on web-based search tasks, the information hints at the dynamics of user interface ergonomics and device input modalities.
In summary, laptops provide more efficient and accurate input methods for web search tasks, reducing mental effort compared to touch-screen PCs where direct finger input and gesture reliance can increase cognitive load during navigation and content input. The study raises questions about whether touch-screen computers are suitable for every computing need.

- For a more efficient and accurate web search, smart-home devices such as laptops are preferred over gadgets like touch-screen PCs, as they reduce mental effort and offer better navigation and content consumption.
- In the realms of technology, it seems that traditional laptops outshine touch-screen PCs in terms of web-based information searches, with studies suggesting lowered cognitive load and increased efficiency.
