Investigating Data Entry Task Performance on a Laptop Under the Impact of Vibration: The Effect of Color

Pavement performance levels causing human health risks

“…It has been reported that WBV has acute detrimental effects on visual acuity equilibrium and manual dexterity [24]. This situation leads to muscle fatigue and muscle fatigue is among the major causes of traffic accidents.…”

Application of colour combinations on visual search tasks under vibration environments

“…Exposure to long-term vibration has been reported to degrade HCI operators’ psychological and physiological outcomes (Graham, 1990; Suzuki, 1998; Mansfield, 2005; Newell and Mansfield, 2006; Dodd et al., 2014). Changes in search tasks and environment (e.g., static versus vibration) can also affect the amount of energy and effort that operators spend in performing cognitive tasks (e.g., visual search) (Lewis and Griffin, 1978; Ishitake et al., 1998; Mallick, 2007; Dodd et al., 2014; Coutts et al., 2019). Despite the benefits of proper use of colour in visual search, the effectiveness of colour in a vibration environment is still not clear.…”

“…They may also suffer from health problems (e.g., low back pain) and experience physiological disorders (e.g., dizziness, discomfort, and disturbance) (Suzuki, 1998; Rosen and Arcan, 2003; Mansfield, 2005; Newell and Mansfield, 2006; Sundström, 2006; Okunribido et al., 2008; Waters et al., 2008; Thamsuwan et al., 2013; Nastaran et al., 2016). Such adverse influence of vibration could further degrade the efficiency of cognitive performance (e.g., visual search) (Lewis and Griffin, 1978; Ishitake et al., 1998; Mallick, 2007; Dodd et al., 2014; Coutts et al., 2019). For example, Lewis and Griffin (1980) simulated five levels of sinusoidal whole-body vibration (i.e., for z -axis, vibration frequency between 2⋅8 and 63 Hz; for x - and y -axes, between 2⋅8 and 32 Hz), where a numeral reading task was conducted.…”

“…Although these studies proposed some strategies (e.g., increasing font size) to mitigate the effects of vibration on visual search performance (Hsieh et al., 2007; Lin et al., 2008; Tan et al., 2018), little research was found exploring the effects of colour combinations on visual search under vibration conditions. For example, Mallick (2007) examined the effect of colour combinations (i.e., white on black and black on white) on people's performance of data entry tasks when using a laptop computing system in moving automobiles along with three levels vibration (0 m/s 2 , 0⋅85 m/s 2 , and 1⋅65 m/s 2 ). Although the authors suggested using white on black to present data entry tasks, the findings were limited by the experimental design, with only two colour combinations tested for the data entry tasks.…”
