With the gradual addition of gesture functions to the user interface (UI) of products such as smart phones and tablet PCs, the sensor market for tracking the hand's motion trajectory with the touch screen has exploded.

According to the latest IHS report, market revenue for proximity gesture sensors in 2013 will surge from $42,000 in 2012 to $123 million. Gesture sensor proximity applications were first used for wireless devices, followed by consumer electronics and automotive. As shown in the chart below, this market will grow significantly in the next five years, with a growth rate of 68% from 2014 to 2015. By 2017, its revenue will reach US$545 million.
There are two types of mobile phone-based gesture solutions on the market today—capacitance and infrared (IR) proximity. On devices that support gesture functions, dedicated proximity sensors detect the movement of the hand in both directions, up, down, left, and right in two or three dimensions. Current touch screen operations require the use of a finger or stylus to directly touch, while capacitive gesture control is further advanced, allowing the user to interact with the device as long as they are close to the screen.
Samsung "Waves Up" and Gestures Enter Smart Phones "The Galaxy S4 released by Samsung is the first smartphone to integrate gesture capabilities," said Marwan Boustany, senior analyst at IHS MEMS & Sensors. "Because of the increasing ability of suppliers to provide gesture solutions, such as U.S. Maxim, Sharp Corp. of Japan, and Lingyao Technology of Taiwan, handset manufacturers using gesture features may follow suit."
IHS believes that the gesture sensor cannot enter the low-end mobile phone within a short time, so the application of gesture function will be limited to mid-high-end mobile phones. Due to the limitation of the screen size of mobile phones, each mobile phone may use only one sensor. However, by 2017, mobile phones will still be the main source of revenue for gesture sensors.
At the same time, personal computers and media tablets will be the fastest growing category of gesture sensors. From 2014 to 2017, its compound revenue growth rate (CAGR) will be as high as 76%. Unlike a mobile phone, a tablet computer may have multiple gesture sensors distributed on the screen to provide corresponding functions.
Mobile phones and tablets are the main application categories for gesture sensors, and wireless communication will be the main application area for gesture functions. From 2013 to 2017, the annual growth rate of gesture sensor revenue in wireless devices will reach 44%.
Consumer electronics and automotive applications begin to embrace gestures In addition to mobile phones and tablets in the wireless space, PC tablets and laptops are also potential growth categories for gesture sensors.
Like the media tablet, the PC tablet can also use multiple gesture components. Because the Microsoft Windows 8 operating system has a very friendly touch design, the tablet equipped with this operating system will be very suitable for gesture interaction.
The automotive field has begun to embrace the gesture interface. Unlike consumer electronics, automotive applications may integrate multiple simple photoelectric sensors into one ASIC. Proximity/infrared gesture solutions can be used in conjunction with other solutions such as capacitive touch sensors on monitors to provide more powerful performance. Such a solution can support the detection of close fingers by a large-sized display in a car dashboard.
In fact, some automotive products have already adopted gesture solutions. For example, Volkswagen's Golf VII chose Halos integrated circuits from Elmos Semiconductor of Germany and Cadillac User Experience (CUE) from General Motors.
IHS noted that sensor vendors are working to provide more advanced infrared proximity gesture solutions, including 3D gesture capabilities - adding motion detection in the z-axis direction.
In the future, camera-based gesture recognition will enter the mobile phone and tablet market. This technology is currently mainly used in high-precision and high-resolution applications - such as Microsoft's introduction of Kinect.
