Form ¡Factors ¡and ¡Input ¡Condi=ons 5

Form ¡Factors ¡and ¡Input ¡Condi=ons - input form factors (size and aspect ratio) 5

Form ¡Factors ¡and ¡Input ¡Condi=ons - input form factors (size and aspect ratio) - input conditions (ability to look at the device, ability to use both hands) 5

Form ¡Factors ¡and ¡Input ¡Condi=ons - input form factors (size and aspect ratio) - input conditions (ability to look at the device, ability to use both hands) - display form factors (device size and aspect ratio, target size) 5

EXPERIMENT ¡1: ¡ device ¡size ¡and ¡input ¡condi=ons 6

EXPERIMENT ¡1: ¡ device ¡size ¡and ¡input ¡condi=ons Hypothesis: 6

  EXPERIMENT ¡1: ¡ device ¡size ¡and ¡input ¡condi=ons Hypothesis: 1. Despite the lack of feedback, looking at the input surface would help position the index finger   6

  EXPERIMENT ¡1: ¡ device ¡size ¡and ¡input ¡condi=ons Hypothesis: 1. Despite the lack of feedback, looking at the input surface would help position the index finger   2. The non-dominant hand could act as a reference frame to position the finger if users were unable to look at the device 6
