The Liar’s Tool Bag is a set of  low-cost tools and materials which allow people to deceive the sensors in common devices such as smart phones. The contents could be customised for particular contexts, but can include:

• Camera Stickers can be placed over cameras, proximity sensors, or light sensors on devices to block visibility
• Microphone Disablers are designed for iPhones and Mac laptops. A headphone plug with only a resistor attached. Disables the internal microphone by making the device think it has an external microphone attached
• Phone Rockers are simple cardboard shapes which a phone can be inserted into. The device can then easily be rocked to simulate walking

• Magnets can be used to disable or disorientate the magnetometers, or compass, on devices

• Sealable Plastic Bag is used to contain the other tools. But it can also be used to deceive the barometer on phones, and give a false altitude reading, if the phone is sealed in with some air and squeezed gently.
