碩士 === 國立臺北科技大學 === 創新設計研究所 === 101 === The computer system evolution from the Desktop to replace notebook, every enterprise constant pursue of the ultimate, to development ultrabook and more efficient of ultraportable laptop products come out, pursuit of product of the ultimate, and develop more efficient thin ultraportable laptop products come out, however, in pursuit of the ultimate behind the notebook without making a breakthrough in ergonomics, the purposes are human factors research and design improvement ultrabook keyboards. Human factors experimental design with adjustable keyboard model experiment used five different sets of angle of the keyboard for input performance tests, testers completed of questionnaires subjective scale; for input performance, a positive inclination of 12 degrees maximum input performance, next is positive 8 degrees, negative rake angle -8 degrees, degrees -12 and 0 degree, the input performance should be change by the input angle; And a positive inclination subjective satisfaction than negative rake angle, angle of 8 degrees higher than the 12 degrees, of the input performance, enter the correct rate was not significantly different. The experimental results are 8 degrees of anteversion keyboard uplift, obvious in the subjective satisfaction highest satisfaction for men and women in all satisfaction slightly different sequence, Women satisfied sequence of positive inclination angle of 8 degrees, the level of 0 degrees, 12 degrees positive and negative inclination angle -8, -12 degrees, the male sequence of angle satisfaction of 8 degrees, 12 degrees and 0 degrees for normal notebook and -8, -12 degrees, Ultrabooks with the split keyboard is same inclination angle of 8 degrees, the proposed multi-segment can be designed according to size and angle for the end-user to adjust the input habits.
