We are creating a new methods of unlocking phones with touch input and sensory input.
Introduction
We are implementing a new way of unlocking phone with touch input and sensory input to prevent accidental unlocking. The methods that our group came up with are “Clock” method touch mechanism and “French word” method for sensory mechanism.
Clock method is when user have to set the virtual clock hands that appear in random position to current time. If the clock hands
French word method is when user have to say the word appear on the screen. If the phone recognize the word said corrently, the phone unlocks.

Conclusion
The unlock mechanism fits the design specification of preventing accidental unlocking because, with the “Clock” method, the user has to aim for the specific time shown in the clock. This prevents accidental unlock because it is hard for accidental unlock to match those two consecutive timing.
The “French word” prevents accidental unlock because it has to recognize the word said by the user which is a specific word on the screen which is in French. Since we are in living in English environment, it is rare for someone to say the exact word that is on the screen.
