Although touchscreens have been around for decades, their capabilities and prevalence are rapidly expanding. They’ve moved from huge, expensive, special-purpose business kiosks in airport terminals and banks to mobile devices that fit in our pockets and toddlers’ hands. They’re still used for business, but also for entertainment, games and phone calls.
As touchscreens move from niche markets to the mainstream, more testers will be testing software targeted at these devices. Test strategies based on physical buttons — on keyboards, mice and cellphones — need to be updated or replaced with new approaches that account for new interaction models and the variations in human hands.
This poster paper will highlight differences between traditional monitor/keyboard/mouse computers and mobile/touchscreen devices. Many of the issues discussed will be accompanied by hands-on examples. While the author provides examples based on her own experience Apple’s iPhone OS devices, the principles should be easily generalizable to mobile touchscreen devices.
