Cen­tral Sta­tion

ABC (Australia) - - TECHNOLOGY -

When de­sign­ing a sign, route num­ber is para­mount. It needs to be large and bold, and should be placed on the kerb side of the bus, ac­cord­ing to Hen­nessy. Lay­out and fonts also need to be con­sis­tent. One of the tech­no­log­i­cal bar­ri­ers is mul­ti­plex­ing, where LEDs flash on and off rapidly to con­serve power and us­age. At Mo­bitec, Hen­nessy has made sure not to use that tech­nol­ogy as it ad­versely af­fects his vi­sion. “My dis­abil­ity en­tails, but is not lim­ited to, nys­tag­mus [in­vol­un­tary rapid move­ment of the eyes] and pho­to­pho­bia [sen­si­tiv­ity to light],” he says. “Whilst mul­ti­plex signs may ap­pear cheaper, they can of­ten ap­pear to me as a blur of danc­ing lines as a bus ap­proached due to my eye move­ments.” He has also been work­ing along­side op­er­a­tors in in­stalling in­for­ma­tion screens and au­dio an­nounce­ments at buses. “They can aid those who may not be able to see things nor­mally from buses or know their lo­ca­tion. The feed­back has been pos­i­tive.”
