Besides its cosmetic and shape, users' evaluation will be affected directly and continuously by gripping it and pressing its keys. This study is to investigate the effect upon users' tactile preference for mouse key. Because the stroke and load of mouse key can be measured by means of digital values, they can help us find the users' favorite setting of different conditions. There are three purposes of this study: (1) To investigate users' favorite value of stroke and load of a mouse key. (2) To find out the relationship between their contrast, proportion and interaction by comparing stroke and load with each other. (3) By personal characteristics of all participants invited in this study, we can compare their differences to evaluate their influence of these individual groups. A total of 34 mouse samples were used in this study, and their settings of left key contain the load range from 45g to 105g and the stroke range from 0.2mm to 1.2mm. The experimental results show that: (1) In the stroke range between 0.2mm and 0.8mm, participants' favorite load value is 60g. However, when the stroke range is over 0.8mm, participants accept only the lightest load value of 45g. Therefore, ideal setting of mouse key is the load of 60g ± 5g and the stroke from 0.2mm to 0.8mm. (2) There are some rules of participants for the load and stroke of a mouse key. The heavier the load of mouse key, the more the tester does not like. Its critical load value is between 70g and 90g. In the short stroke range less than 0.8mm, the load value affects participants more than the stroke value. Most participants prefer the setting value of short stroke and light load based on observing the score distribution from every mouse sample. Besides, the experimental results show that the participants from different groups have a similar preference patterns from the interaction diagram. Therefore, it shows that most users have similar cognition and response when using a mouse. (3) The analysis of personal characteristics of participants (i.e., gender, age, hobby and usage time) shows that their characteristics may not have strong influence on their operation of a mouse. (4) Participants can clearly distinguish the key load increments of about 10g and the key stroke increments between 0.3mm and 0.4mm.
