Human-centered design
CASIO employs human-centered design methods during product development. We produce prototypes based on data obtained from user interviews and behavior observation that mimics actual worksites and then perform testing and verification from the perspectives of usability specialists and users alike. The results are fed back to the design teams, and shapes and designs are perfected through repeated refinements.
A body shape designed to ensure a comfortable grip
We conducted tests on a series of actions involving holding the terminal, viewing the screen and scanning then designed the body shape, grip material, surface treatment, and other details on the basis of the test results. This process resulted in an ergonomically shaped grip that fits comfortably in the hand and permits operation for many hours without fatigue.
Downward scanner angle to facilitate easier scanning
We scanned barcodes placed at various heights, measuring work times and muscle load and also performed eye movement tracking. Analysis of the resulting data led to adoption of a downward scanning angle that places little strain on the eyes, arm, or hand and ensures reliable scanning even of barcodes in high and low locations while viewing the screen at the same time.
Key shape designed for ease of input
We performed actual input operation using design prototypes with different combinations of key shape, size and pitch then compared ease of input. By compiling data on the operating experiences of test subjects and making repeated improvements, we arrived at a key design that enables comfortable, accurate input.
Large 4.3″ touchscreen
The IT-G500 has a 4.3-inch transmissive TFT LCD screen that supports WVGA ?800 × 480 dots?. The LCD offers excellent visibility indoors or outdoors and displays even small text with high resolution.The enlarged screen area makes it possible to display more information to increase effectiveness when the IT-G500 is used to place orders or search product information. The resistive touch panel can be operated even while wearing gloves.
