3. • Advancement of computational power into small and
small packages
e.g (Portable, wearability, comfortable, aesthetics)
• Sophisticated display of small devices despite their
diminutive dimensions
• Standard of touch screen interaction technique do not
scale down so well
Novel Solution
• Front mounted screen with side edges touch sensor
5. • Baudisich and Chu present a highly effective system
that incorporates touch input on the rear of a device
• Butler optical system and Harrison and Hudson’s use
pysical controller to an adjacent area of device’s screen
• Feiner and Ashbrook et al. present how a physical bevel
can support pointing activity around the front facing
perimeter of watch like devices.
• Spelmezan system, pressure sensors are mounted
around a mobile phone to detect squeeze-based input.
8. • Edge interaction is a rapid, accurate and effective way to
conduct targeting tasks
• User heavily relied on edge based touches
• User focus on finger taps and touches
•
