Enhanced haptic feedback for handheld mobile computing devices

An article of manufacture comprising a computer-readable non-transitory storage medium having instructions stored thereon to cause a processor to perform operations including:

• detecting a user touch input on a touchscreen input/output (I/O) interface of a handheld mobile computing device;
• determining one or more characteristics of the user touch input, including one or more of a duration of the user touch input, a direction of the user touch input, a speed of the user touch input, or a force applied during the user touch input;
• and
• generating a control signal comprising one or more pulses to drive one or more actuators included in the handheld mobile computing device to generate an adjustable haptic effect, wherein the control signal is generated based, at least in part, on the determined one or more characteristics of the user touch input.

A device comprising:

• logic, the logic at least partially implemented in hardware, the logic to:
• detect a user touch input on a touchscreen input/output (I/O) interface of a handheld mobile computing device;
• determine one or more characteristics of the user touch input, including one or more of a duration of the user touch input, a direction of the user touch input, a speed of the user touch input, or a force applied during the user touch input;
• and
• generate a control signal comprising one or more pulses to drive one or more actuators included in the handheld mobile computing device to generate an adjustable haptic effect, wherein the control signal is generated based, at least in part, on the determined one or more characteristics of the user touch input.
