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. （點擊英國《每日郵報》網(wǎng)站查看原文）

蓋茨欲為學生配“情緒手鐲”

?????? 微軟公司董事長比爾?蓋茨計劃為學生配備“情緒手鐲”，以此來調查他們對課程有多大興趣。

?????? 據(jù)英國《每日郵報》報道，比爾和梅琳達?蓋茨基金會將斥資110萬美元購買皮膚電流反應測試手鐲，希望通過手鐲來衡量學生是否覺得老師的課有吸引力。

?????? 這一行動是比爾?蓋茨評估、提高學校師資計劃的一部分。

?????? 據(jù)悉，“情緒手鐲”能測量皮膚的導電性，而皮膚導電性會隨著水分含量的變化而變化。

?????? 由于汗腺是由神經系統(tǒng)控制，因此皮膚導電性可以作為情緒反應的一種依據(jù)。
