Waving your hand to answer a call when your hands all occupied writing a code or making a cake might be reality for future windows phone. As reported by AllThingsD, a Korean Company, Pantech, has created gesture support for up coming Vega LTE line of phones in November.
What is interesting about this is its not for Windows Phone but rather uses the Israel’s eyeSight Mobile Technologies on Android Phones which allows anybody to answer a phone call by using a swipe action over the phone, shuffle songs when playing music and watching your albums. These make prefect sense even when you are driving.
What will be interesting to see is if Microsoft is happy about it or will Google Try to buy this and make it available only for Android Phone.
