Touchless sensing technology: the next HMI paradigm

02 December 2014

According to Frost & Sullivan, touchless sensing technology is set to transform industries ranging from consumer electronics to gaming.

Touchless sensing technologies were initially used in applications such as bathroom dispensing units and automatic doors that required motion sensing in order to create response. 

With advanced touchless sensing technologies such as gesture sensing, voice commands, brain wave sensing and eye tracking, the application potential of these solutions has greatly expanded. In consumer application segments, gesture sensing can be expected to be the most promising touchless interface technology.
 
New analysis from Frost & Sullivan, ‘Touchless Sensors Technology - 9 Dimensional Assessment,’ expects next-generation interfaces enabled by cutting-edge touchless technologies to penetrate the consumer electronics, healthcare, automotive, security, military and gaming industries. 

Of the various segments and sub-segments, mobile electronic devices will offer the biggest opportunities to touchless sensing technology providers.
 
In recent years, haptics and touch technology have become dominant paradigms in human machine interface (HMI), which have become a prominent research area due to the proliferation of versatile digital devices. The physical keyboard is slowly retreating – although not obsolete – and giving way to touch-screening modes that allow users to not only move the screen, but also enlarge the screen and access virtual keyboards to interact with applications and the device itself. However, the status of the touch-based technology is being challenged by touchless HMI technologies.
 
“Various approaches and methodologies are being investigated to improve user interaction with digital devices,” explained Technical Insights research analyst, Jabez Mendelson. “Touchless sensing technology presents itself as one such approach offering numerous value-added benefits to users, which includes easy and natural interaction with digital devices.”
 
However the report states that efforts to encourage users to adopt touchless sensing systems are still needed. Touchless sensing technology providers also need to address the problems and challenges faced in practicability in implementing the solution and also the technical limitations faced by them.
