Tablet Exterior

• Display size: The smaller the screen the more sacrifices may be required with regards to easy readability under all kind of lighting conditions; font sizes and questionnaire design. 7 inch tablets will do a good job for most interviewer-assisted surveys. For all situations were all or part of the questionnaire is self-administered, 10 inch to 12 inch tablets should be selected.
  

• Screen resolution: A minimum screen resolution of 1280 x 800 is recommended but not required

• Battery life: At minimum, the device should run a full work day work day without recharging.

• Weight of device: The lower the weight, the better. Always consider that the interviewers or other personnel have to carry the device around the full day.

• Overall quality of touch screen: Slow reaction to touch or insensitivity to light touch quickly gets cumbersome. Too much glare distracts and is hard on the eyes.

• Suitability for outdoor use: If outdoor usage and/or exposure to direct sunlight is required for all or some of your mobile surveys, check out the device in direct sunlight before you buy.

• Availability of accessories for the device: Look primarily for protective gear, e.g. to absorb shock in the event of a fall.
