Microsoft supremo Bill Gates wants to fit school students with mood bracelets to measure how interested they are in their lessons, the Daily Mail reported.

The Bill and Melinda Gates foundation is spending $1.1 million testing galvanic skin response bracelets to see if they can measure whether students find their teachers engaging.

The move is part of the billionaire's mission to evaluate and improve the quality of teachers.

The bracelets measure how well the skin conducts electricity, which varies with its moisture level.

Sweat glands are controlled by the nervous system so skin conductance can be used as an indication of emotional response. （点击英国《每日邮报》网站查看原文）

盖茨欲为学生配“情绪手镯”

       微软公司董事长比尔•盖茨计划为学生配备“情绪手镯”，以此来调查他们对课程有多大兴趣。

       据英国《每日邮报》报道，比尔和梅琳达•盖茨基金会将斥资110万美元购买皮肤电流反应测试手镯，希望通过手镯来衡量学生是否觉得老师的课有吸引力。

       这一行动是比尔•盖茨评估、提高学校师资计划的一部分。

       据悉，“情绪手镯”能测量皮肤的导电性，而皮肤导电性会随着水分含量的变化而变化。

       由于汗腺是由神经系统控制，因此皮肤导电性可以作为情绪反应的一种依据。
