Tiivistelmä
Mobile devices are being used to benefit a variety of personal and working environments. One potential working environment is newspaper distribution, where mental tiredness during night-time working hours can result in loss of efficiency and motivation. Reading the addresses manually from the address book whilst simultaneously keeping track of the subscriber’s newspaper preferences and delivering them to the right door increases the cognitive load on the distributor and can lead to early exhaustion. Distributors could benefit from the automation of their manual home address book by having its electronic version on their mobile devices. However, merely automating the manual book keeping does not decrease the required visual attention during the work. Incorporating multimodality decreases the cognitive load on the distributors and makes the system more usable, allowing them to complete their job efficiently and accurately. A prototype system of the presented solution was developed and tested in a real working environment to prove its feasibility. A new interaction technique was introduced combining simple gesture recognition for accelerometer equipped mobile devices, as well as providing auditory and haptic feedback for the distributor. An intermediate comparative study between manual distribution and presented solution was made in order to measure the usefulness of the system in the context of time and efficiency. The feedback reveals that the system is more easily operable if the presented solution allows the distributors to add customizable gesture recognition.
