Abstract
On mobile devices that provide alerts (ringtones, alarms, notifications) via vibrations, vibration parameters may in some cases be set to intensities unsuited to the user’s context. This can result in missed notifications in loud environments or disruptive notifications in quiet environments. This disclosure describes techniques to provide haptic notifications on mobile devices in an adaptive manner consistent with the user context. With user permission, readings from device sensors (such as but not limited to, microphone, ambient light sensor, proximity sensor, and accelerometer) are used to determine the user’s context/environment, e.g., the ambient noise and light levels, device motion, etc. The vibration intensity is adjusted based on the determined context/environment such that vibrations are noticeable but not disruptive. A user that is stationary in a quiet, indoor environment receives a low vibration intensity, while a user in a loud, outdoor environment with the device in their pocket receives a high vibration intensity. The techniques, referred to as adaptive haptics, can improve user experience by bringing calls/notifications to the user’s attention in a context-sensitive manner.
