Children computer mouse use and anthropometry

Abstract

Studies have shown that increased computer use among adults in occupational settings is associated with the development of cumulative trauma disorders; however, the need to address how adult-sized mice and keyboards are affecting children is becoming increasingly important as both access to and use of computers is increasing among today's youth. To address the potential mismatch that exists between child stature and computer input device size and activation force, we have applied existing, age-specific, anthropometric data to elements of device design, including mouse size (length, width, height, switch location), and mouse-button activation forces. Trends supported the development of smaller computer input devices with lower activation forces for smaller statured individuals including children. Distinct and consistent trends in size delineations were seen across gender and age groups-trends that correlate well with grades and schooling in the United States education system . Three to four mouse sizes would be recommended: a mouse sized for adult and high school males; one for adult and high school females and junior high males; one for elementary school children, aged 6 to 10 years; and possibly a mouse for the smallest users who are less than six years old.

Optimal Sensor Position for a Computer Mouse

“…They found no practical performance differences among these. However, it was later discovered that the size of a regular mouse is not suitable for children [27]. Hand size must be considered in choosing a comfortable mouse.…”

Ergonomic Design of a Computer Mouse for Clients With Wrist Splints

“…We expected that a rear-hump mouse or volar-based splint might cause discomfort, but this hypothesis was not supported. First, both mice used in this study were relatively small (length 5 9.5 cm) compared with a standard mouse (12.6 cm; Hughes & Johnson, 2012). Participants could hold the mouse at its distal end without losing the clicking movements.…”

“…In contrast, other studies applied hand length as an anthropometric indicator to calculate the size of computer devices. Hughes and Johnson (2012) used hand length to calculate the length, width, height, and switch location of the mouse and suggested four different mouse sizes for users of different ages and genders. Similarly, Oude Hengel et al (2008) used hand length to categorize users with smaller or bigger hands and found that users with bigger hands had more wrist extension and muscle activation when using a smaller mouse.…”
